About ORV CISMA
The Ohio River Valley Cooperative Invasive Species Management Area (ORV CISMA) is a coalition of nonprofits, agencies and businesses working to control and remove invasive species in a 22-county area in the Ohio River Valley. The ORV CISMA is made up of stakeholder groups including Boone, Campbell and Kenton County Conservation Districts, Boone National Forest, Natorp’s Nursery, Great Parks of Hamilton County, Cincinnati Parks, Clermont County Park District, Ohio Department of Agriculture, Ohio Invasive Plant Council, Little Miami Conservancy, Oxbow Inc., Kentucky Nature Preserves Commission, and Cincinnati Nature Center, Great Parks of Hamilton County and Cincinnati Parks.
The data below is provided by land owners and land managers within the ORV CISMA Coalition.
Primary Concern Invasive Plants Species
Primary Concern species have been identified by property managers to include: Honeysuckle, Callery Pear, Winter Creeper, and Lesser Celandine.
Interact with the map below to view each site's primary concern species and severity.
ORV CISMA Stakeholder Sites
In the following maps, explore the severity of primary concern invasive species across highlighted stakeholder sites.
Navigate maps using the arrow(s) on the left and right of the screen.
Honeysuckle Severity
This map shows the severity of Amur Honeysuckle across ORV CISMA stakeholder sites; represented in a color ramp from yellow to red for increasing species presence.
Amur Honeysuckle is a noxious woody shrub, introduced to southern Ohio in the late 1950s intended for erosion control and is now rampant across Ohio and much of the Eastern United States. Honeysuckle is a dominant invasive and crowds out native plants, harming native flora, fauna, and local waterways. It is successful in most environments and thrives in disturbed soils, along roadways, and in urban and suburban areas.
For more information and to learn how to ID Honeysuckle in your area, see the Ohio Department of Natural Resources (DNR) Identification Guide below.
Callery Pear Severity
This map shows the severity of Callery pear across ORV CISMA stakeholder sites; represented in a color ramp from yellow to red for increasing species presence, grey indicates data is not available.
Callery Pear is a noxious woody tree introduced to the United States in the early 1900s for ornamental purposes and to improve disease resistance in fruit-bearing pear varieties. It was initially planted widely in urban and suburban areas but has now become rampant across Ohio and much of the Eastern United States. Callery Pear is a dominant invasive species that crowds out native plants, harming native flora, fauna, and local ecosystems. It is successful in most environments and thrives in disturbed soils, along roadways, and in urban and suburban areas.
For more information and to learn how to ID Callery pears in your area, see the Ohio Department of Natural Resources (DNR) Identification Guide below.
Winter Creeper Severity
This map shows the severity of Winter Creeper across ORV CISMA stakeholder sites; represented in a color ramp from yellow to red for increasing species presence, grey indicates data is not available.
Winter Creeper is a noxious evergreen vine introduced to the United States in the early 1900s as an ornamental ground cover and erosion control plant. Initially planted widely in urban and suburban areas for its fast growth and year-round greenery, it has now become rampant across Ohio and much of the Eastern United States. Winter Creeper is a dominant invasive species that smothers native plants, disrupting native flora, fauna, and local ecosystems. It thrives in most environments, particularly in disturbed soils, forest understories, and along roadways, where it can climb and overwhelm trees and shrubs.
For more information and to learn how to ID Winter Creeper in your area, see the Invasive Plant Atlas Identification Guide below.
Lesser Celandine Severity
This map shows the severity of Lesser Celandine across ORV CISMA stakeholder sites; represented in a color ramp from yellow to red for increasing species presence, grey indicates data is not available.
Lesser Celandine is a noxious perennial plant introduced to the United States in the late 1800s as an ornamental ground cover due to its bright yellow flowers and early spring bloom. Initially planted in gardens and urban landscapes, it has now become rampant across Ohio and much of the Eastern United States. Lesser Celandine is a dominant invasive species that forms dense mats, outcompeting native spring ephemerals and disrupting local ecosystems. It thrives in moist environments, such as floodplains, streambanks, and wetlands, where its rapid growth and extensive root systems prevent the establishment of native plants.
For more information and to learn how to ID Lesser Celandine in your area see the Ohio Department of Natural Resources (DNR) Identification Guide below.
Additional Invasive Plant Species
While the species above are the most common invasive species found at our stakeholder sites, other species are prevalent and require continuous monitoring and maintenance.
