The Great Bear Rainforest, located along the Pacific Coast of British Columbia, is a great example of a thriving yet vulnerable ecosystem.In this temperate rainforest, over 2,500 salmon runs take place a year. Why Are Sea Turtles Important? Sea turtles are a "keystone species", which means they are an important part of their environment and influence other species around them.

Female orcas can live up to 90 years, and male orcas live up to 60 years. Forage fish are an indispensable part of the marine food web on the Pacific coast. This reduces run-off into rivers and streams which in turn reduces flood damage. They're featured prominently in the stories and art of the Coast Salish people, and their presence is important for local tourism. Answer. Polar bears are at the top of the food chain. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Healthy ecosystems depend on plant and animal species as their foundations.

This project has determined that killer whales are sensitive to perturbations such as oil spills but has not yet determined the long-term consequence (which may include extinction) or the recovery period required. If a keystone species is removed from a habitat, the natural order can be disrupted, which impacts other wildlife and fauna in different ways. As a species, whales are divided up into two categories: toothed and untoothed. Sharks help prevent particular species from crowding out others or overpopulating. Since then, the sea otter has become an important poster species for the ecology movement: a lovable, cuddly sea mammal that was saved from extinction thanks to international action.
