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.
Arizona-Sonora Desert Museum.
The rapid spread of buffelgrass through the Sonoran Desert rivals climate change and water scarcity as our region's most pressing environmental issue. Buffelgrass is one of many plants that were brought here from other parts of the world. Lacking the insects, diseases, and other organisms that helped keep them in check back home, some have spread like wildfire, much to the detriment of our native plants and animals. Buffelgrass is the worst of these invasive plants because it is not only invading our desert, but transforming our formerly fire-proof desert into a fire-prone grassland. The fight to control buffelgrass is the fight to save an ecosystem and some of the most magnificent stands of saguaros in the world. Volunteer for a buffelgrass pull, register your own buffelgrass pull, or request a presentation or ID guide.
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.
