Stop the Spread.

Seneca Lake Watershed Hemlock Initiative

The purpose of this project is to retain a healthy eastern hemlock (Tsuga canadensis) population in the Seneca Lake Watershed to protect water quality, stabilize landscapes, and maintain essential environmental systems. The immediate hope is to control Hemlock Woolly Adelgid (HWA) infestations to a level where biological control agents, currently under development, can sustain long-term management.
