What is a CISMA?

A CISMA is a Cooperative Invasive Species Management Area. The SW x SW CISMA is a cooperative effort between Cass, Berrien, and Van Buren Counties’ Conservation Districts as well as different partner organizations across the tri-county area. This project was funded in part with funds from the Michigan Invasive Species Grant Program through the Departments of Natural Resources, Environmental Quality, and Agriculture and Rural Development.

 What is an invasive species?

An invasive species is a plant or animal that is nonnative to Michigan and is likely to cause harm Michigan’s economy, environment, or human health. The SW x SW CISMA has identified the following species as species of interest in Cass, Berrien, and Van Buren Counties:

Asian Long Horned Beetle

Chinese Yam

European Frog-bit

Flowering Rush

Black & Pale Swallow-wort

Hemlock Woolly Adelgid

Japanese Knotweed


How to control invasives once found? 

Be sure to check in with our office as you begin control methods so we can assist, document the project and ensure proper control methods are used (mowing knotweed will just encourage more growth).  More detailed info for each species follow these links.
