In 2002, with funding from theMontrose Trustees Restoration Program, the park (in conjunction with partner,Institute for Wildlife Studies) began to introduce juvenile bald eagles to the northernChannel Islands. For example, the endangered Asian elephant is a spiritual icon in Asia. Studies of the life cycle impacts of the six major energy generation sources have shown wind energy has the lowest environmental impact of any form of electricity generation, as it emits no air or water pollution, uses no water in the generation of electricity and creates no hazardous or radioactive waste requiring permanent storage.

Greater Honeyguides live up to their name and range throughout sub-Saharan Africa: There, the brown-and-cream-colored birds, which eat bees wax and insect larvae, literally guide people to honey. In fact, pollution-free, renewable wind energy was built on a legacy of care and has expended significant resources proactively minimizing its impact on wildlife while representing an economical solution to mitigating the effects of climate change. In order to mitigate golden eagle predation on island foxes, The Santa Cruz Predatory Bird Research Group, with the support of the Park Service and The Nature Conservancy, relocated golden eagles to distant sites on the California mainland. In 1963, scientists counted just over 400 pairs of bald eagles in the lower 48 states.

This could pose a problem for recovery of bald eagles on the northern Channel Islands (see below), because pinnipeds and seabirds contain more DDE than do marine fish, due to bioaccumulation at higher trophic levels.
