Found 10 records similar to Intertidal Invasive Species - Terra Nova
Terra Nova National Park monitors intertidal invertebrate communities using a line transect and quadrat sampling method. The survey focusses on invertebrate community composition and diversity, and should detect presence of invasive marine species.
The European Green crab is a pan-global invasive exotic species. Its detrimental effects are well documented, including effects on eelgrass and soft-shelled clams and have defined the species of crab as an 'ecosystem engineer'. A population control program was initiated in 2009 whereby modified shrimp traps are used to remove as many green crabs from Kejimkujik's estuaries as possible. These management efforts are evaluated through standardized monitoring whereby 14 traps are deployed for the same period of time in the same place annually.
Terra Nova National Park censuses tern nests on 23 small islands in Newman Sound, to monitor species productivity and population dynamics.
Tow, catch, and biological information for crab caught during the annual snow crab research vessel trawl survey in the southern Gulf of St. Lawrence.
Terra Nova National Park conducts weekly shorebird surveys during August and early September in order to monitor the abundance of Greater Yellowlegs and other shorebird species.
Aquatic invasive species pose economic and ecological threats to Canada's coastal waters. In response, Fisheries and Oceans Canada (DFO) has established monitoring programs to detect and track the spread of aquatic invasive species, including European Green Crab, in Canadian waters. Fukui traps have been deployed annually at both new and long-term monitoring locations throughout coastal British Columbia.
Each summer, environmental community groups collect important data to determine if groupings of fish, shrimp and crab – what is called a community- can be used as an indicator of the health status of bays and estuaries. Sampling was conducted from May through September for the first years then from June through August. In 2018 and 2019, the sampling was conducted just once in each estuary. Community group members and staff sample six stations once a month in their designated estuary.Fish, shrimps and crabs are collected with a beach seine net and later released live back to the water once identified and counted.
Shellfish monitoring has been accepted by the Pacific Bioregion of Parks Canada as a measure of ecosystem health in soft substrates in the intertidal zone. Surveys are used to capture the status of selected bivalves within the national park reserve to determine long-term population numbers and trends in response to natural and/or human disturbance. Shellfish surveys are completed annually in May at selected sites in the Broken Group Islands Unit of Pacific Rim National Park Reserve. Clam and oyster datasets are presented separately, as surveys follow different field protocols, but both use variations of a method of randomly selected quadrat sampling along a transect.
