This partnership resulted in the Great Bear Rainforest Agreement, which was signed between First Nations . Invasive species are any species that are non-native to a particular ecosystem and whose introduction and spread causes, or are likely to cause, socio-cultural, economic or environmental harm or harm to human health. Nutria are large rodents native to South America. Also, not every new non-native species is equally threatening, so gauging the level of risk and responding accordingly is important to avoid misallocating limited resources on species of low ecological or economic concern. He has written extensively about threats to trees and forests. People crossing oceans brought not only new pathogens, but also new plants and their retinues of insects and microbes.
