A prescribed fire was conducted at Rock Spring in October 2023 as part of Marin Water’s approach to a more resilient, ecologically healthy watershed.

This self-guided tour explores the connection between the health of local forests and Marin City’s history.

Roy's Redwoods Preserve is a magical place, home to especially large redwood trees and other inhabitants like the California giant salamander. It's one of only four parks in Marin County to enjoy old-growth redwoods, and the only one accessible to people of all abilities.

These self-guided walks offer a glimpse into what forests need to be healthy, and how our One Tam partnership is working to address these threats on our public lands, improve forest health, and evolve our understanding of caring for forests.  

Anticoagulant rodenticides (AR) are used to control pests, but secondary exposure can affect non-target species like raptors. Researchers tested juvenile Red-tailed Hawks to learn more. 

Data from seven fall raptor migration sites show that not only have kestrel numbers have been declining across North America, they've also been getting smaller. 

Red-tailed Hawks are common raptors in the Bay Area, yet males and females can be difficult to tell apart. Researchers used DNA and small differences in size to better understand their migration.

At GGRO, we observe that female raptors typically migrate before males and juveniles typically migrate before adults. How does this compare to findings at other observation stations?

We don't know much about Broad-winged Hawks' migration along the Pacific Flyway, so GGRO volunteers tracked the journeys of five. Where did they go?
