Conservancy land stewardship on the Preserve is as dynamic as the landscape. We face numerous challenges from invasive weeds and the SOD pathogen, and incorporate defense against proliferation of these threats in our management practices. We further promote our native species with restrictions and approvals of vegetation planted on the Preserve. Our prohibited plant list is a guide to promote native species and discourage aggressive invasive plants and we have identified California native grass mixes that help preserve the genetic composition of our grasslands.

Openlands Habitat Projects

By design, approximately 8,000 acres of The Preserve are protected for their scenic and environmental qualities as Openlands under conservation easement with the Conservancy. Learn more.

Native Grasslands Restoration

While most of North America’s native ecosystems are grasslands, the conservation challenges facing coastal California grasslands are unique. Learn more.

Sudden Oak Death

Sudden Oak Death (SOD), a disease caused by the exotic pathogen Phytophthora ramorum, has killed hundreds of thousands of trees since its introduction to California just over 20 years ago.  Learn more.

Invasive Weeds

Invasive plant species pose a threat to the delicate biodiversity and natural beauty of The Preserve. Left unchecked, these species have the potential to out-compete sensitive native species and disrupt our treasured native plant communities. Learn more.

Night Sky and Nocturnals

Moonlight, as it waxes and wanes in the night sky, gives key signals to our wild creatures, letting them know the passage of time and seasons. Learn more.
