Spot an invasive species? Let us know.

Report sightings

 

CRISP reports invasive species observations to iMapInvasives, where scientists and land managers from around the world can view the distribution of invasive species throughout New York and other states.

You need an account to report sightings in iMapInvasives. You can sign up for one here. If you want to report an invasive species without an iMapInvasives account, you can always let us know about it here.

iMapInvasives is an on-line, GIS-based data management system used to assist citizen scientists and natural resource professionals working to protect our natural resources from the threat of invasive species. In New York, it is sponsored by the New York Natural Heritage Program.

Hemlock
Woolly Adelgid

Hemlock woolly adelgid (Adelges tsugae) (HWA) is an invasive forest pest native native to Japan. Since its introduction in Virginia in the 1950’s, this insect has spread all throughout the East Coast, from Canada to Southern Appalachia, decimating Eastern (Tsuga canadensis) and Carolina (Tsuga caroliniana) hemlocks. The adelgids’ egg sacs- which look like small woolly white balls, similar to the tip of a Q-tip- can be found on the underside of hemlock branches, at the base of the needles, where the insect feeds. They feed off the tree’s parenchyma cells, taking resources from the tree. This eventually causes a lack of new growth, and typically tree mortality. This destructive intruder has been spreading through the Hudson Valley and the Catskills since the late 1980’s and is now widespread.
