audioBats are economically and ecologically important animals, providing ecosystem services such as pollination and predation of insects. In general, bat populations are believed to be declining. Researchers used acoustic sampling to inventory bat populations at Eugene O'Neill National Historic Site, John Muir National Historic Site, and Point Reyes National Seashore. All of these parks are on the wildland-urban interface.
Once an actress with abandoned dreams of joining a convent, Carlotta Monterey O’Neill collaborated with her playwright husband Eugene O’Neill on some of his most famous work during their five years in “Tao House” in Danville, California.
Eugene O’Neill National Historic Site consists of 13.19-acres of land and is situated within Las Trampas Hills at 700 feet above sea level on the western edge of the city of Danville, California. Within the historic site, buildings, roads, several small orchards, and ornamental vegetation were developed between the years 1880 and 1944, and characterize the property as a small working ranch.

The Pacific Border straddles the boundaries between several of Earth's moving plates on the western margin of North America. This region is one of the most geologically young and tectonically active in North America. The generally rugged, mountainous landscape of this province provides evidence of ongoing mountain-building.

To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.
