Coastal Species at Risk - Prince Edward Island
The sustainability of species at risk is an important assessment of ecosystem biodiversity. The status of each threatened species can infer how well an ecosystem is functioning to maintain species diversity. Assessing the status of coastal species at risk, including piping plover (Charadrius melodus), Gulf of St. Lawrence aster (Symphyotrichum laurentianum), and beach pinweed (Lechea maritima), is valuable as an indicator of ecological integrity in the coastal ecosystem in PEI National Park. The population abundance of both Gulf of St. Lawrence aster and beach pinweed is assessed against the historical abundance levels and whether or not it has an increasing or decreasing trend in population size. Piping plover is assessed on both number of breeding pairs present, as well as their reproductive productivity. Thresholds of 15 breeding pairs and 1.65 fledglings per pair have been established.
