Potomac Highlands Cooperative Weed and Pest Management Area.
Smithsonian Environmental Research Center.
Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.
Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.
Potomac Highlands Cooperative Weed and Pest Management Area (West Virginia).
Maryland Department of Natural Resources.
Do you hike, ride, bird, camp, fish, or otherwise recreate in state parks, forests or wildlands? Lend YOUR eyes to help Maryland's biodiversity! The Maryland Natural Heritage Program designed Statewide Eyes to allow volunteers and researchers alike to collect more information about invasive plants on state lands quickly. Volunteers (like you!) use a free mobile application called the Mid-Atlantic Early Detection Network (MAEDN) to identify, photograph and map the location of invasive plants, focusing on ecologically significant sites.

The Asian citrus psyllid and citrus greening (Huanglongbing) could be a death sentence for California citrus trees - but with support from California residents, we can save the citrus trees that we all know and love.
