Since 1985 ACR has protected Toms Point from development and for the benefit of the natural systems of Tomales Bay. Through the archeological excavations of Tsim Schneider, Lee Panich and team, we also have come to understand the cultural importance of places like Toms Point—both historic and contemporary—to native people of California and are deeply grateful to continue on a path of shared purpose with regional tribal members and researchers.

Their work recently was highlighted in the San Francisco Chronicle and is recommended reading for our North Bay community.

Say Hello! to P19, the male offspring of P1, Sonoma's Super Mama and P5, the resident male in the area. The Living with Lions team captured and collared P1’s 13-month-old offspring on Wednesday evening. Now known as P19, the young male looked healthy and well cared for by his mom. We’re grateful to have had a chance to collar him before he disperses. Our team on this collaring event included: Director and Principal Investigator Quinton Martins, veterinarian Graham Crawford, Bouverie Resource Ecologist Jennifer Potts, Research Associate Alex Hettena, and Research Technician Sheila McCarthy.

P19 marks the third of P1’s cubs (from three different litters) that we have collared. It was terrific to meet him again at close proximity after seeing him and his sibling for the first time...

On July 29, mountain lion P14, a young male we've been tracking since January, was killed in Mendocino County after a depredation permit was issued by the California Department of Fish and Wildlife (CDFW). The permit was requested by a Point Arena landowner after 12 sheep were killed. This is the fourth collared mountain lion killed for livestock depredation since our study, Living with Lions, began in October 2016.

The story of P14 goes back to the first week of 2019 when property owners Paul and Maria woke to find their two adult llamas dead in the field on their property near Jenner, CA. The large but rather old llamas—used to protect a small flock of goats against predators—were attacked and killed by a male mountain lion. In California, the offending animal would typically...

Several months ago, Prescribed Fire Specialist Jared Childress had the pleasure to lead a small group of basket weavers from the Federated Indians of Graton Rancheria (FIGR) to the pygmy redwoods at Bouverie Preserve. They were looking for California hazel (Corylus cornuta var. californica) and were pleased by the quality of the post-fire shoots — thin, straight pliable basketry shoots that typically regrow only 1-2 years after burning. We learned so much observing their collection activities. Generously, the FIGR weavers group gifted the Preserve this traditional basket from the collected hazel. We look forward to sharing the story and the basket with the school kids when they return to the trail in the fall.

With a keen eye toward climate change and potential impacts on preserve ecology and infrastructure, ACR contracted with Laurel Collins of Watershed Services and Jason Pearson of Lotic Environmental Services to conduct a preliminary geomorphic assessment of the four watersheds in the Martin Griffin Preserve (MGP).  Project objectives included:

  • Provide a watershed level understanding of the current and long-term processes that affect flow, sediment sources, and sedimentation in the lower alluvial fans adjacent to...

"Good stewardship entails looking after those in our care," says Quinton Martins, director of Living with Lions, in the recent Game Changers special edition of North Bay BIZ magazine. It's no surprise they found Quinton's optimism for community-driven conservation a compelling story but along the way they also discovered just how the project is winning the hearts of school children, landowners, volunteers and research partners.

As Executive Direction John Petersen says, "The work Quinton's doing is a perfect fit for ACR's mission—land stewardship, nature education and conservation science. We're fortunate to have him and his expertise as part of our team."

ACR’s Fire Forward program on Saturday conducted a 27-acre controlled burn of annual grassland and oak savannah at Bouverie Preserve near Glen Ellen. Ecological objectives for this event were timed to reduce non-native and invasive plants, promote native bunchgrasses and native wildflowers and to offer a ‘live fire’...

From the latest edition of Marine Ornithology: In the Bay Area, the Double-crested Cormorant population has recovered from significant declines to reach population sizes comparable to those from the late 19th century, when only one colony offshore at the Farallon Islands was known. We were especially elated to observe that on the colony at Hog Island on Tomales Bay, formed in 2001, has become the largest in the study area since 2011.

ACR was pleased to co-author this report on the changes in abundance and distribution of nesting Double-crested Cormorants in the SF Bay Area from 1975-2017. The report was spurred by severe nesting disruptions observed during the construction of the new Bay Bridge. Download the full report from...

Over the past three decades, a great deal of research has been gathered on snags and their role in forest and wetland ecosystems. Snags, better known as dead trees or logs, play a crucial role in maintaining biodiversity in a number of habitats including oak woodlands, pine forests and riparian zones. In California alone, snags are home to over 160 different species, which is why government land managers have designated them as “special habitat elements.”

Forest ecologist Jerry Franklin states, “A dead tree is more alive than a live tree.” Dead trees are a vital part of nutrient cycling within forests. Logs, in particular, contribute to the nutrient reserves and chemical and physical characteristics of forest soils or waterways.

According to Sally Duncan of the U.S....
