The B.C. Nature Trust & Kootenay Lake Ospreys

Description

The Nature Trust started buying key wildlife habitat with a small amount of money left over from a Canadian Centennial grant. Since then, the trust has acquired thousands of hectares of critical habitat. It has no income source now but does not touch its principal; spending only the interest. The Osprey story tells how populations of this big fish hawk have returned to great abundance on Kootenay Lake. Numbers around North America fell sharply due to DDT residues. As they increased in the Kootenays a decline in nutrient levels caused great decline in the food source fishes used by ospreys. But they are such efficient predators they appear able to get what they need from a fishery reduced to a remnant of former abundance.
