We Protect Open Space for the Benefit of All

Moderate to strenuous 6-mile hike through POST-protected land providing context to the human & natural history of this beautiful preserve!

POST is a proud sponsor of this exciting talk with Wildlife Biologist Patrick Kolar about Golden Eagle breeding populations in the Diablo Range of California!

Join Open Space Authority for a presentation of an ongoing study of golden eagles in the area and discuss how this broader research in the Diablo Range is being used to avoid or mitigate impacts to breeding pairs of eagles at one of the largest and densest known breeding populations of golden eagles in the world.
