RE: 2026 Stormwater Facility Native Planting Maintenance
Dear Ms. Deckert:
NES Ecological Services (NES) is pleased to submit this proposal for the maintenance of native plantings
within and around 25 stormwater facilities located in the City of Oshkosh, Winnebago County, WI. The
proposed scope of services for the maintenance, cost and schedule are outlined below.
SCOPE OF WORK
Tasks referenced below will be found in the 2025 City of Oshkosh Stormwater Facility Assessment
Report.
9th and Washburn Basin
The native communities will require continued management over a period of time if healthy communities
are to be restored and maintained. The primary concern within the wetland is the elimination of purple
loosestrife and cattail, while crown vetch and birdsfoot trefoil removal need to be addressed in the prairie.
Recommendations are as follows:
• A spring prescribed burn within the prairie and wet meadow is recommended (Tasks 4 & 5). The
burn will eliminate thatch, set-back cool season species, assist with woody species control and
blacken the earth which will spur the growth of native species and rejuvenate the planting.
• In the wet meadow and prairie communities, timely herbicide applications (Task 6) and selective
hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species
should be conducted. Species to be addressed during these site visits include but are not limited
to Canada thistle, bull thistle, hybrid cattail, Queen Anne’s lace (Daucus carota), crown vetch,
birdsfoot trefoil, purple loosestrife, reed canary grass, sweet clover, Phragmites, common teasel
and Kentucky bluegrass.
• NES recommends continued herbicide treatments of cattail to fully eliminate the populations in
the emergent community. Spot treatments and hand wicking will be the most applicable as the
population has been depleted to the point where broadcast applications won’t be necessary. If
follow-up treatments are not conducted, the species can easily re-occupy the previously infested
area. As these populations are eradicated, seeding and/or planting of native vegetation may be

City of Oshkosh Native Planting Maintenance Proposal
December 2025 2
recommended to help reduce future invasions by non-native species and establish a native
community. Follow-up woody vegetation control around the pond’s perimeter should be
conducted (Task 14). If left unchecked, woody vegetation could populate the entire shoreline and
wet meadow community making future pond maintenance activities more difficult. Trees could
compromise berms and extensive willow thickets could eliminate desirable herbaceous
vegetation.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress at this site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Anchorage Channel – South & North Segments
This basin/channel will require intensive work addressed over a period of time if a healthy native
community is to be established. Recommendations are as follows:
• In the wet meadow and prairie communities, timely herbicide applications (Task 6) and selective
hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species
should be conducted. Species to be addressed during these site visits include but are not limited
to Canada thistle, bull thistle, burdock, cattail, Queen Anne’s lace, crown vetch, purple
loosestrife, Phragmites, reed canary grass, sweet clover, teasel, and Kentucky bluegrass. Special
attention should be given to newly opened areas following largescale woody vegetation removal
in late 2025.
• Continued and follow-up woody vegetation control in the channel should be conducted (Task 14).
If left unchecked, woody vegetation could re-populate the wet meadow and prairie communities
making future facility maintenance activities more difficult.
• To achieve “Good” and “Basic” rankings for this basin, cattail and Phragmites will need to be
eliminated, and native species established in the wet meadow zone in the north segment and
portions of the southern segment. Based on the current condition of the wet meadow zone,
continued herbicide applications (Task 6) will be required in the north segment and spot
applications in the southern segment.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).

Armory Basin
This basin will require intensive work to be addressed over a period of time if a healthy native community
is to be established. Recommendations are as follows:
• To achieve a “Good” ranking for this basin, cattail will need to be eliminated from the emergent
zone. Based on the current condition of the emergent zone, broadcast herbicide applications
(Task 6) will be required in 2026. Supplemental planting will then be required and should be
conducted in 2027 and 2028, provided cattail has been sufficiently suppressed. Conducting a
prescribed burn within the prairie would help suppress invasive species within the community
and spur native species growth.
• The City did not originally wish to pursue further vegetative maintenance at this site. However,
while meeting with City Staff in 2022, NES recommended mowing applications to continue
reducing teasel populations. Mowing activities (Task 8) should continue.
• Woody vegetation control around the pond’s perimeter should be conducted (Task 14).
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
The 2022 RFP did not include maintenance activities around this basin; however, mowing activities were
later added and should continue in 2026. Continued discussions with City staff will be required to
determine the extent of additional, future work desired within and around this particular stormwater
facility.
Aviation Basin
The site’s overall “Best” condition reduces maintenance activities and the time it takes to cover the site;
however, the fencing structure over the basin offsets that by increasing implementation time due to
reduced access and maneuverability for staff and equipment. Recommendations are as follows:
• NES recommends selective herbicide applications (Task 6) and hand pulling/cutting/mowing
(Task 8) be conducted to target cool season grasses and invasive forb species. Species to be
addressed during these site visits include but are not limited to thistle spp., burdock, Queen
Anne’s lace, reed canary grass, and sweet clover.
• Monitoring for cattail and purple loosestrife should continue in the emergent zone. Due to the
low density, control should be performed by hand wicking plants (Task 6).

• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may

and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Baldwin Basin
This is a high priority basin for the City due to its high visibility. To achieve the City’s desired goal,
continued effort will be required to control cattail, purple loosestrife, and woody species, while the area
previously planted as prairie would need to be re-planted as continued mowing has degraded it to a point
where it can no longer be salvaged. Recommendations are as follows; however, as City staff knows, an
adjacent neighbor is unfortunately making it difficult to complete maintenance activities:
• Patches of hybrid cattail should be mowed (Task 7) in late winter/early spring to reduce thatch
and allow for easier follow-up herbicide treatments.
• In the higher quality wet meadow segments, timely herbicide applications (Task 6) and selective
hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species
should be conducted. Species to be addressed during these site visits include but are not limited
to thistle spp., Queen Anne’s lace, purple loosestrife, reed canary grass, hybrid cattail and sweet
clover.
• Mowed areas along the inside of the retention walls contain a mix of species, primarily invasives
such as Queen Anne’s lace and thistle. Continued mowing has destroyed the planting; therefore,
City staff must determine if these activities are to continue. Whether or not mowing continues
within select areas, signs should be posted around the basin’s perimeter to discourage mowing in
higher quality habitats. Management activities can then be planned accordingly within the areas.
• Any remaining dense cattail populations should be broadcast sprayed while scattered plants and
Phragmites should be hand wicked (Task 6) to reduce impacts to the native species. Due to the
high-quality wet meadow adjacent to these stands, it is likely native species will continue to re-
populate the sites. The treated areas will be monitored to determine follow-up activities.
• Follow-up woody vegetation control throughout the basin should be conducted (Task 14). This
control may also be implemented via mowing (Task 8) as has been the case in the past few years.
If left unchecked, woody vegetation could populate the entire wet meadow community making
future pond maintenance activities more difficult. Extensive willow thickets could also eliminate
desirable herbaceous vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to

achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Fair Acres Basin
The wetland area has endured intensive herbicide treatments to control hybrid cattail. Monitoring of the
wetland area will need to be done in order to determine the need for planting within the zone. The upland
area will also require continued maintenance to control invasive species and improve habitat quality.
Recommendations are as follows:
• In the prairie community, timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species should be
conducted. Species to be addressed during these site visits include but are not limited to thistle
spp., burdock, Queen Anne’s lace, crown vetch, purple loosestrife, reed canary grass, sweet
clover and Kentucky bluegrass.
• To achieve a better ranking in the emergent zone, native species will need to begin re-populating
the zone and any remaining cattail will need to be addressed via spot treatments or hand wicking
in order to prevent the species from re-populating.
• If necessary, emergent plants and herbivore fencing will need to be installed in previously treated
cattail stands unless native species are successful in re-populating the zone. Vegetation growth
within the emergent zone should be monitored during the 2025 growing season to determine the
need, if any, for planting in 2026.
• Follow-up woody vegetation control around the pond’s perimeter should be conducted (Task 14).
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Fernau Basin
Routine maintenance, including mowing and spot herbicide treatments should continue to help maintain
and improve the condition of the basin. Recommendations are as follows:
• In the prairie community, timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species should be
conducted. Species to be addressed during these site visits include but are not limited to thistle

spp., burdock, Queen Anne’s lace, crown vetch, purple loosestrife, reed canary grass, sweet
clover, common teasel and Kentucky bluegrass. Mowing activities along the perimeter of the
community should cease to prevent further damage to the planting and achieve the City’s goal of
80-90% native vegetative cover.
• Cattail is the only invasive species within the emergent zone that is of concern. The population
has been reduced to little coverage of scattered plants interspersed throughout the emergent zone,
but control should continue to be performed through spot foliar treatments and/or hand wicking
(Task 6).
• Follow-up woody vegetation control around the pond’s perimeter should be conducted (Task 14).
• Although not part of the planting, invasive species such as buckthorn, cottonwood and teasel
located along the southern and eastern property boundaries should be controlled to prevent their
spread into the planting.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
James Road Basin
This rather large basin has the potential to provide good native species diversity and cover; however,
maintenance activities should be conducted to fully control invasive species on the site and improve the
overall quality of the facility. Recommendations are as follows:
• A spring prescribed burn within the wet meadow & emergent community is recommended (Tasks
4 & 5). The burn will eliminate thatch, set-back cool season species, assist with woody species
control and blacken the earth which will spur the growth of native species and rejuvenate the
planting.
• Spot herbicide applications (Task 6) and selective hand pulling/cutting/mowing (Task 8) should
be conducted to target cool season grasses and invasive forb species in the emergent and wet
meadow communities currently containing >60% native species coverage. Species to be
addressed during these site visits include but are not limited to thistle spp., sweet clover,
Kentucky bluegrass, reed canary grass, hybrid cattail, common reed, birdsfoot trefoil, willow and
Queen Anne’s lace. The two species that require the greatest effort to control are reed canary
grass and cattail.
• To achieve a “Good” ranking for the emergent zone of this basin, cattail will need to be
eliminated. Based on the current condition of the emergent zone, broadcast herbicide
applications (Task 6) will be required. Additional treatments will likely be required following
Docusign Envelope ID: 05CEEB5F-2759-4528-ABAC-491EAB70208D
City of Oshkosh Native Planting Maintenance Proposal
December 2025 7
largescale woody vegetation removal with improved access to cattail populations. Treated cattail
will need to be mowed or burned to allow this community to be planted with emergent plugs and
herbivore fencing installed in the year following complete treatment. If mowing or burning
treated cattail is not an option, planting this community will have to wait a year to allow cattail
thatch to break down.
• Woody vegetation control throughout the site should be conducted in conjunction with the above
invasive species control activities. If left unchecked, woody vegetation could populate the entire
emergent and wet meadow communities making future pond maintenance activities more
difficult. Trees could compromise berms and extensive willow thickets could eliminate desirable
herbaceous vegetation. As discussed in a meeting with City staff in August of 2024, the City will
conduct this woody vegetation removal.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Libbey North Basin
Routine maintenance, including mowing and spot herbicide treatments should continue to help maintain
and improve the condition of the basin. Recommendations are as follows:
• In the emergent and prairie communities, timely herbicide applications (Task 6) and selective
hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species
should be conducted. Species to be addressed during these site visits include but are not limited
to Canada thistle, bull thistle, burdock, cattail, Queen Anne’s lace, reed canary grass, and sweet
clover.
• Selective treatments following the emergent planting that target cattail, purple loosestrife and
Phragmites are recommended to prevent planting degradation.
• Woody vegetation control around the pond’s perimeter should be conducted (Task 14). If left
unchecked, woody vegetation could populate the entire shoreline making future pond
maintenance activities more difficult. Trees could compromise berms and extensive willow
thickets could eliminate desirable herbaceous vegetation.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur

(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Libbey South Basin
This basin will require intensive work, particularly within the prairie, over a period of time if a healthy
native community is to be established. Recommendations are as follows:
• In the emergent and prairie communities, timely herbicide applications (Task 6) and selective
hand pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species
should be conducted. Species to be addressed during these site visits include but are not limited
to Canada thistle, bull thistle, burdock, cattail, Queen Anne’s lace, Teasel, reed canary grass, and
sweet clover.
• Selective treatments targeting cattail, purple loosestrife and Phragmites are recommended to
prevent planting degradation.
• To achieve a “Good” ranking for this basin, the prairie will need to be managed and rehabilitated
from its current state. The prairie planting can still likely be salvaged, based on the species
present. Emergent plantings will need to become established and expand from their planting
areas into the remainder of the pond’s safety shelf.
• Woody vegetation control around the pond’s perimeter should be conducted (Task 14). If left
unchecked, woody vegetation could populate the entire shoreline making future pond
maintenance activities more difficult. Trees could compromise berms and extensive willow
thickets could eliminate desirable herbaceous vegetation.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to

budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Northwest Industrial Park
To ensure invasive species do not hinder the native plantings installed in 2023 and 2024, maintenance
activities should be conducted which includes:
• In the prairie and wet meadow segments, timely herbicide applications (Task 6), broadcast
mowing (Task 7) and selective hand pulling/cutting/mowing (Task 8) to target cool season
grasses and invasive forb species should be conducted. Species to be addressed during these site
visits include but are not limited to thistle spp., Queen Anne’s lace, purple loosestrife, reed canary
grass, hybrid cattail, wild parsnip, cutleaf teasel, crown vetch, and birdsfoot trefoil.

Oshkosh Corporation Basin
Routine maintenance, including mowing and spot herbicide treatments should continue to help ensure a
healthy native community is established. Recommendations are as follows:
• The emergent community was planted in 2022. Selective herbicide treatments (Task 6) targeting
cattail, purple loosestrife and Phragmites are recommended to achieve a “Good” ranking for this
basin.
• If necessary, woody vegetation control around the pond’s perimeter should be conducted (Task

Oshkosh North High School Basin
The site’s great overall condition minimizes maintenance requirements and the amount of effort to
accomplish them. Continued routine maintenance activities will ensure the communities remain in great
shape. Recommendations are as follows:
• Spot herbicide applications (Task 6) and selective hand pulling/cutting/mowing (Task 8) should
be conducted to target cool season grasses and invasive forb species in the prairie community.
Species to be addressed during these site visits include but are not limited to thistle spp., burdock,
garlic mustard, Queen Anne’s lace, reed canary grass and sweet clover.
• Purple loosestrife is the only invasive species within the emergent zone of concern. Control
should be performed by cutting and bagging seed heads and spot treating or hand wicking the
plants (Task 6).
• Follow-up woody vegetation control around the pond’s perimeter should be conducted (Task 14).
• Although not part of the planting, buckthorn located in the adjacent woodlot should be controlled
to prevent its spread into the planting.
• It is recommended that muskrats be trapped to prevent burrows, shoreline erosion, and herbivory
of native vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to

Parkway Basin
This basin will require intensive work, particularly within the prairie, over a period of time if a healthy
native community is to be established. Continued routine maintenance activities will ensure the wet
meadow community remains in great shape. Recommendations are as follows:
• Spot herbicide applications (Task 6) and selective hand pulling/cutting/mowing (Task 8) should
be conducted to target cool season grasses and invasive forb species in the prairie community.
Species to be addressed during these site visits include but are not limited to thistle spp., wild
parsnip, Queen Anne’s lace, reed canary grass and sweet clover.
• Cattail and reed canary grass are the invasive species of greatest concern within the wet meadow.
Due to the low density, control should be performed carefully by hand wicking or spot treating
(Task 6).
• Woody vegetation control around the basin’s perimeter should be conducted (Task 14).

• It is recommended that muskrats be trapped to prevent burrows, shoreline erosion, and herbivory
of native vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Sawyer Creek Rural II Basin
This basin will require routine maintenance activities over a period if healthy native communities are to
be established. Recommendations are as follows:
• Spot herbicide applications (Task 6), broadcast mowing (Task 7), and selective hand
pulling/cutting/mowing (Task 8) should be conducted to target cool season grasses and invasive
forb species in the prairie community. Species to be addressed during these site visits include but
are not limited to thistle spp., wild parsnip, Queen Anne’s lace, reed canary grass and sweet
clover.
• Cattail and reed canary grass are the invasive species of greatest concern within the wet meadow
and emergent communities. Due to the density, control should be performed carefully via foliar
spot treatment (Task 6).
• A late summer/early fall, broadcast herbicide treatment targeting broadleaf invasive species,
particularly thistle and wild parsnip should be conducted in the No-Mow areas adjacent to the
native plantings (Task 6).
• It is recommended that muskrats be trapped to prevent burrows, shoreline erosion, and herbivory
of native vegetation.
• The last recommendation is that all work be documented and tracked over time to determine

• In the prairie community, timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species should be
conducted. Species to be addressed during these site visits include but are not limited to thistle
spp., burdock, Queen Anne’s lace, crown vetch, purple loosestrife, reed canary grass, sweet
clover, common teasel and Kentucky bluegrass.
• Cattail is the greatest invasive species of concern within the emergent zone. The population has
been reduced to a coverage of scattered plants interspersed throughout the emergent zone, but
control should continue to be performed through spot foliar treatments and/or hand wicking (Task
6).
• Follow-up woody vegetation control around the pond’s perimeter should be conducted (Task 14).
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.

South Park Basin
To ensure invasive species do not hinder the native plantings installed in 2020, 2023 and 2024,
maintenance activities, similar to what was conducted in 2025, should be conducted which includes:
• In the wet meadow community, timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species should be
conducted. Species to be addressed during these site visits include but are not limited to thistle
spp., burdock, purple loosestrife and reed canary grass.
• Cattail and purple loosestrife should be removed from within the emergent zone via herbicide
applications (Task 6) and selective hand pulling/cutting/mowing (Task 8).
• Follow-up woody vegetation control should be conducted (Task 14).
• The last recommendation is that all work be documented and tracked over time to determine

Southwest Industrial Park Basin A
To ensure invasive species do not hinder the native plantings installed in both the emergent zone and
prairie, timely herbicide and mowing activities will be required to ensure a healthy native community is
established. Recommendations are as follows:
• To achieve a “Good” ranking for this basin, the prairie community was re-seeded in the fall of
2023. Management activities including herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) during the 2025 growing season should be conducted to remove
invasive species. Species to be addressed during these site visits include but are not limited to
thistle, birdsfoot trefoil, burdock, Queen Anne’s lace, sweet clover, reed canary grass and wild
parsnip.
• If necessary, woody vegetation control should be conducted (Task 14).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Southwest Industrial Park Basin B
Improvements in the emergent zone have been noticeable and should only require limited efforts moving
forward. Timely herbicide and mowing activities will need to continue to ensure a healthy, prairie
community is established. Recommendations are as follows:
• To achieve a “Good” ranking for this basin, the prairie community was re-seeded in 2022.
Management activities including herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) should be conducted to remove invasive species. Species to be
addressed during these site visits include but are not limited to thistle, burdock, Queen Anne’s
lace, sweet clover, reed canary grass and wild parsnip.
• Due to the success of previous cattail treatments, limited efforts of hand-wicking and or spot
treating (Task 6) should be conducted to keep the species at bay.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to

achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Southwest Industrial Park Basin C
Timely herbicide and mowing activities will need to continue to ensure a healthy, prairie community is
established. The positive trend in native species re-establishment in previously treated cattail areas is
encouraging. Recommendations are as follows:
• To achieve a “Good” ranking for this basin, the prairie community was re-seeded in 2022.
Management activities including spot mowing (Task 8) and herbicide applications (Task 6)
should be conducted to remove invasive species. Species to be addressed during these site visits
include but are not limited to thistle, burdock, Queen Anne’s lace, sweet clover, Kentucky
bluegrass, reed canary grass and wild parsnip.
• The emergent zone has responded well to previous cattail treatments at this basin, as native
species have become well established within those areas. As long as this trend continues in the
areas that were treated for cattail in 2025, the zone should continue filling in with native species
and will not need supplemental planting in the future. Any remaining or newly sprouted cattail
should be treated carefully via spot treatment or hand wicking (Task 6).
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments
and maintenance will be prepared and submitted to the City of Oshkosh each year activities occur
(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Southwest Industrial Park East Basin
This basin will require intensive work and needs to be addressed over a period of time if a healthy native
community is to be established. Recommendations are as follows:
• Due to the density of invasive species present, the site likely has a significant seedbank that may
need to be depleted prior to re-establishing native vegetation. If redoing the prairie and wet
meadow is a priority, the process should begin by mowing the site in spring and then conducting
three herbicide applications (Tasks 6 & 7) throughout the growing season to remove all
vegetation. Depending on the results of those applications, the process may need to be repeated
for an additional year or two. Native prairie and wet meadow seed mixes can then be dormant
seeded in the fall.
• To achieve a “Good” ranking for the emergent zone of this basin, cattail will need to be
eliminated. Based on the current condition of the emergent zone, broadcast herbicide
applications (Task 6) will be required. Additional treatments will likely be required following
largescale woody vegetation removal with improved access to cattail populations. Treated cattail
Docusign Envelope ID: 05CEEB5F-2759-4528-ABAC-491EAB70208D
City of Oshkosh Native Planting Maintenance Proposal
December 2025 15
will need to be mowed or burned to allow this community to be planted with emergent plugs and
herbivore fencing in the year following complete treatment. If mowing or burning the treated
cattail is not an option, planting this community will have to wait a year to allow cattail thatch to
break down.
• Woody vegetation control around the pond’s perimeter should be conducted (Task 14) in
conjunction with the above seedbed preparation activities. If left unchecked, woody vegetation
could populate the entire shoreline and wet meadow community making future pond maintenance
activities more difficult. Extensive willow thickets could eliminate desirable herbaceous
vegetation.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it should
not be continually repeated. Sometimes adaptive management needs to be implemented to
achieve the ultimate goal. On the other hand, if something works very well at this site, it may
work well at one or all of the other basins being managed. A report summarizing the assessments

(Task 13). A meeting to discuss the results and determine future maintenance needs based on
budgetary constraints will be conducted upon completion of report review by City staff (Task 1).
Southwest Industrial Park Middle Basin
This basin will require intensive work and needs to be addressed over a period of time if a healthy native
community is to be established. Recommendations are as follows:
• Due to the density of invasive species present in the “Poor” ranked portions of the prairie and wet
meadow communities, the site likely has a significant seedbank that may need to be depleted
prior to re-establishing native vegetation. If redoing the prairie and wet meadow is a priority, the
process should begin by mowing the site in spring and then conducting three herbicide
applications (Tasks 6 & 7) throughout the growing season to remove all vegetation. Depending
on the results of those applications, the process may need to be repeated for an additional year or
two. Native prairie and wet meadow seed mixes can then be dormant seeded in the fall. If the
prairie is to be re-seeded, mowing within the community must cease to achieve the City’s goal of
80-90% native vegetative cover. This mowing has inhibited the establishment of the prairie
originally installed.
• Timely herbicide applications (Task 6) and selective hand pulling/cutting/mowing (Task 8) to
target invasive forb species should be conducted in the remaining portions of the prairie and wet
meadow. In addition, 6-8” mowing (Task 7) of dense flowering wild parsnip populations may be
necessary to prevent these plants from going to seed. Species to be addressed during these site
visits include but are not limited to wild parsnip, Canada thistle, bull thistle, burdock, Queen
Anne’s lace, crown vetch, purple loosestrife, reed canary grass, sweet clover, common teasel and
birdsfoot trefoil.
• To achieve a “Good” ranking for the emergent zone of this basin, cattail will need to be
eliminated. Based on the current condition of the emergent zone, broadcast herbicide
applications (Task 6) will be required. Additional treatments will likely be required following
largescale woody vegetation removal with improved access to cattail populations. Treated cattail
will need to be mowed or burned to allow this community to be planted with emergent plugs and

herbivore fencing in the year following complete treatment. If mowing or burning treated cattail
is not an option, planting this community will have to wait a year to allow cattail thatch to break

• Woody vegetation control around the pond’s perimeter should be conducted (Task 14) in
conjunction with the above seedbed preparation activities. If left unchecked, woody vegetation
could populate the entire shoreline and wet meadow community making future pond maintenance
activities more difficult. Trees could compromise berms and extensive willow thickets could
eliminate desirable herbaceous vegetation.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
vegetation.

Southwest Industrial Park West Basin
This basin will require intensive work and needs to be addressed over a period of time if a healthy native
community is to be established. Recommendations are as follows:

Westhaven Clubhouse Basin
Routine maintenance, including mowing and spot herbicide treatments should continue to help maintain
and improve the condition of the basin. Recommendations are as follows:
• In the prairie community, timely herbicide applications (Task 6) and selective hand
pulling/cutting/mowing (Task 8) to target cool season grasses and invasive forb species should be
conducted. Species to be addressed during these site visits include but are not limited to thistle,
Kentucky bluegrass, wild parsnip and reed canary grass. If necessary, the “Basic” area located in
the northwest corner of the facility should be overseeded (Task 9) in the spring to increase native
species diversity, similar to 2024.
• The emergent zone has responded positively to previous cattail treatments at this basin, as native
species have become partially established within those areas. As long as this trend continues in
the areas that were treated for cattail in 2024 and 2025, the zone should continue filling in with
native species and will not need supplemental planting in the future. Remaining or newly
sprouted cattail should be treated carefully via spot treatment or hand wicking (Task 6).
• Monitoring and treatment of nuisance algae/vegetation in the submergent zone of the pond are
recommended. The use of natural bacteria enzymes and/or phosphorus reduction agents when
possible will maximize pond health. Monthly visits will reduce time between visits, keep algae
blooms to a minimum, and allow management tools to focus on nutrients and organic
matter/muck.
• It is recommended that muskrats be trapped to prevent burrows, shoreline erosion, and herbivory
of native vegetation.
• The last recommendation is that all work be documented and tracked over time to determine
progress of the site. Quick assessments should be made by the individual conducting work on the
site each time they are at the basin. If something is not working on this particular site, it

Westowne
This basin will require intensive work and needs to be addressed over a period of time if a healthy native
community is to be established. Recommendations are as follows:
• Timely herbicide applications and spot mowings (Task 6 & 8) should be conducted to control
invasive species such as but not limited to hybrid cattail, purple loosestrife, Canada thistle, yellow
rocket and curly dock. The “Poor” areas located in the prairie and wet meadow communities
should be overseeded in the spring to increase native species diversity, similar to 2024.
• To achieve a “Good” ranking for the emergent zone in this basin, the installed native species in
this community will need to successfully establish. Selective herbicide applications (Task 6) to
hybrid cattail and purple loosestrife are recommended in this community.
• Woody vegetation control throughout the basin should be conducted (Task 14). If left unchecked,
woody vegetation could further populate the entire wet meadow and emergent communities
making future pond maintenance activities more difficult. Trees could compromise berms and
extensive willow thickets could eliminate desirable herbaceous vegetation.
• Muskrats should be trapped to prevent burrows, shoreline erosion, and herbivory of native
