What We Do at CRISP


CRISP's resources are geared towards dealing with Early Detection Rapid Response invasive species, as well as certain forest pests (e.g. Hemlock Woolly Adelgid).  At this time, CRISP rarely assists in the eradication of some highly abundant invasives--such as multiflora rose--but our staff is more than happy to consult with individuals regarding identification of and control methods available for these species.  Send any questions regarding invasive species that threaten the Catskills region to:

CRISP Engagement Policy is here jthompson@catskillcenter.org or (845) 586-2611.

Regional Vision for Hemlock on the Landscape:

Hemlock cathedral forests distributed across the landscape that provide quality habitat, important natural benefits, and provide an essential cultural resource.

Current situation and project overview:

Within the Catskill Regional Invasive Species Partnership region hemlock dominated stands comprised ~ 10% of forest and have unique ecosystem functions. . Hemlock Woolly Adelgid (Adelgis tsugae), a small aphidlike insect native to Asia, threatens the persistence of hemlock in the Catskills and was originally detected in the Catskills in the late 1980s and has since spread through many hemlock stands across the region. Hemlock Woolly Adelgid feeding damages the canopy of the host tree and causes eventual mortality. Hemlock Woolly Adelgid is regarded as the greatest threat to hemlock forests in the region, and has been found to infest most surveyed hemlock stands in the Catskill Mountains. Another important hemlock pest, Elongate Hemlock Scale (Fiorinia externa), has been documented as widespread in the eastern Catskills. To date, half of 35 surveyed hemlock stands were in “moderately severe to severe decline.”


1. Protect and maintain genetic diversity of hemlocks across the landscape over the long-term.

2. Protect hemlock forests that provide important cultural and economic value, including historical, recreational, educational, and environmental benefits.

3. Preserve and protect hemlock stands in locations with cold water streams and brook trout habitat.

Early Detection Network and Outreach

In partnership with Cornell Cooperative Extension of Green County, CRISP has developed an early detection network of trained Master Gardener volunteers and Cornell Cooperative Extension staff in each county in our region to act as the first line of defense for early detections of new invasive species.

Asian Longhorned Beetle Public Outreach

CRISP is working with Vibrant Creative to develop a multi-media campaign to reach a broad audience with the message “Don’t Move Firewood” and information on how to identify the beetle and its symptoms.
