Definition
Partnership across jurisdictional boundaries to manage invasive
species in a defined area
![Page 3: CWMA/CISMA - BugwoodCloud](https://reader030.fdocuments.in/reader030/viewer/2022020622/61ee6ab69d2d470ab4435ce1/html5/thumbnails/3.jpg)
Why?
• Communication
• Strategic plan
• Prioritize species
• Inventory, map, monitor
• Coordinate management
• $
• Landscape approach to protecting LWR

Cooperative Weed Management Areas
USFWS
TNC
TNC
1. Defined geographical area distinguished by a common geography, invasive species problem, community, climate, political boundary, or land use.
2. Involvement or representation of the majority of landowners and natural resource managers in the defined area.
3. Establishment of a steering committee.
4. Commitment to cooperation.
5. Development of a comprehensive plan that addresses the management or prevention of one or more invasive species.
What are the five basic characteristics?

Comparison
among 3 years of
survey points
within a convex
hull polygon of
overlapping
surveyed area

What we would hope to see over time (given
treatment)
Fewer points
Smaller acreage infestations
Fewer “dense” infestations

What does this mean?
Spread but reduced cover suggests treatment works
Treat and re-treat
We’re not out of the woods on the Lake Wales Ridge
