And for over 25 years, hundreds of Bay Area volunteers have tracked the numbers and movements of these magnificent birds, often considered
indicators of healthy ecosystems, and set up the first and only bird of prey monitoring system in California at the Golden Gate Raptor Observatory (GGRO).
According to a study published in the journal Science, the study from the Wildlife Conservation Society, found that from the 94 ecological processes that serve as the
foundation of healthy ecosystems on earth — from sea to land — 80 percent of which shows signs of distress due to climate change.
Because amphibians can ingest toxins through their skin, they are drastically impacted by pollutants and chemicals in the environment, so a thriving frog and toad population is considered an
indicator of a healthy ecosystem.
