As global sea temperatures continue to increase due to climate change, aquatic invasive species are better able to spread and flourish. Rising populations of European green crab and the coffin box are two invasive species that are currently affecting Newfoundland and Labrador's native marine species, such as oysters and scallops, and marine habitat, such as kelp beds and eelgrass.
Warmer sea temperatures is one of multiple risk factors that can increase the spread and population growth of invasive species by extending the length of reproductive seasons, shortening the time to reach sexual maturity, and increasing feeding and growth. Other invasive species, such as Vase Tunicate, Violet Tunicate and Golden Star Tunicate, have been observed in the province in lower numbers, but could become a bigger threat with further water temperature increases.
This application was created by the Government of Newfoundland and Labrador's Office of Climate Change and Energy Efficiency. It is designed to provide a broad overview of how climate change is impacting Newfoundland and Labrador, and facilitate meeting curriculum outcomes for the high school course Environmental Science 3205.
