King County Department of Natural Resources (Washington). Water and Land Resources Division.
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.
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.
Coastal Conservation Association Maryland.
An angling-based effort to provide important data to the Maryland Department of Natural Resources, USFWS, and other management agencies on what you're seeing on the water. Information related to the number of fish you catch during a given time, as well as the length and weight of the fish you catch is important to fishery managers. It is also vital to investigate the feeding habits of invasive fish to help understand the short and long-term impacts that their existence may cause on native species. It is important that the public recognizes the impacts that these species can have on our natural ecosystems, and does not continue the spread of these fish. Species tracked include: snakehead, blue catfish, and flathead catfish.
Event was held April-October 2021. Monthly drawings for prizes are based on your catches reported. Every invasive you catch-photo-enter (via the iAngler app) earns you a chance of winning.
Washington State Recreation and Conservation Office. Washington Invasive Species Council.
Washington Pest Watch is a citizen science initiative led by agencies and universities at the front line in protecting our state’s natural resources and economy from invasive species. You don't have to be an entomologist or biologist to participate in the network; the majority of network members are everyday people who keep their eyes peeled for the signs and symptoms of high priority invasive species and report them to agencies to aid in detections and rapid response. Just keep an eye out in your yard, your neighborhood, or when enjoying outdoor activities. Be aware and report what you spot—it’s simple and easy.
