What Is a CISMA?

CISMA stands for “cooperative invasive species management area.” It’s a broad-scale approach to managing invasive species across the landscape, waterbodies, and high-risk pathways (e.g., roads and trails) of a large geographic area.

Kenai Peninsula CISMA

Invasive plants and animals don’t recognize human boundaries like public and private lands. They hitch a ride wherever people travel.

The KP-CISMA, coordinated by the Homer Soil & Water Conservation District, is a volunteer partnership dedicated to preventing and managing invasive species across the Kenai Peninsula.

Our geographic area includes the six-million-acre Kenai Peninsula, the 10-mile Kenai Isthmus at Portage, Turnagain Arm, and communities across Kachemak Bay: Seldovia, Port Graham, and Nanwalek.
