"In conclusion, the subject Bald Eagle nest is unlikely to be impacted by project activities outside a 120-foot distance buffer as long as the landscape buffer (trees) within this area and the on-site wetland is maintained. However, to satisfy the City of Seattle and shield the applicant, obtaining an Eagle Incident Take permit is highly recommended. No other mitigation, site development alternatives, or ongoing management practices should be necessary."
1) Learn and leave established native flora undisturbed.2) Remove invasive species and then wait to see if native plants begin to grow without assistance. (When native plants start on their own, then these plants or trees are likely the most appropriate flora for the habitat.)3) Scatter seeds from nearby native plants in a similar habitat.4) If you feel you must add a new plant then select a native plant while considering how the plant fits with the specific habitat and understanding the plant's logical place in the normal succession of native plants.
My friend Elaine Chuang shared several resources (that were new to me) from the January 2022 Washington Ornithological Society meeting. By the way, Elaine credits Vicki King for researching and supplying this information. Keystone native plants are an important new idea. Douglas Tallamy in the book "Nature's Best Hope " explains that caterpillars supply more energy to birds than any other plant eater. He also mentions that 14% of our native plants, i.e. Keystone Plants, provide food for 90% of our caterpillars. This unique subset of native plants and trees enables critical moths, butterflies, and caterpillars that in turn provide food for the great majority of birds, especially during the breeding season.
Here are the top two relevant links.

New! Updated resources for adding keystone native plants to your yard.
This updated collection includes a variety of new and different books, perspectives, and interactions between plants, birds, and insects. Thank you to Vicki King for continuing to collect all of these exceptionally helpful works. Also, thank you to each of the individuals who contributed.
