POST protects open space on the Peninsula and in the South Bay for the benefit of all. As a private nonprofit land trust, we have been responsible for preserving more than 90,000 acres since our founding in 1977. POST works with private landowners and public agencies to create a network of protected lands so that present and future generations benefit from the careful balance of rural and urban landscapes that makes our region extraordinary.

Mountain lions are famously elusive, yet their influence extends throughout the Santa Cruz Mountains. They shape the behavior of deer, coyotes, and countless other species, helping maintain the ecological relationships that keep forests healthy and resilient. These hidden connections remind us that local plants and animals — humans included — are part of an intricate web of life.

Our Wildlife Linkages Program Manager, Marian Vernon, dives deep into mountain lion ecology on our blog and gives insight into the importance of balance in ecosystems. Read all about it here 👉 https://bit.ly/3VnI6ga

Are you ready for spooky season? We are starting it off with a bang! Sudden oak death is no joke. It was first recognized affecting oaks in California in the mid 1990s and has had devastating effects on coastal forests in California and Oregon. Despite its name it does affect more than just oaks. Its known to infect manzanita, gray pine, acacia, and even eucalyptus.

🌳 suddenoakdeath.org has a plethora of information if you're concerned about the pathogen and how to manage it!

🎬✨ What a night of inspiration and connection!

On Saturday, about 300 community members (and some lovely pups! :dog:) gathered at Devil’s Canyon Brewing Company for POST’s fourth annual Representation Matters Film Festival. The evening was intentionally designed to celebrate diverse voices of adventures where people from all backgrounds could see themselves and their communities reflected. Together, we experienced five powerful films celebrating diverse voices, accessible adventure and the many ways people connect with the outdoors.

From meeting a snake and exploring community booths to sharing pizza under the evening sky, the night was full of curiosity, connection and joy.

As two guests shared:

💬 “I enjoyed the welcoming atmosphere and great collection of films!”

💬 “The film ‘Best Day Ever’ was so inspiring and uplifting.”

A huge thank you to our community partners:
Santa Clara Valley Bird Alliance, San Mateo County Bird Alliance, Bay Area Ridge Trail, Things That Creep, San Francisco Bay Bird Observatory - SFBBO, and Climate Resilient Communities. Be sure to check them out to learn about ways to get involved with our local community organizations.

Missed the in person festival? You can still join us from home. Our virtual screening is available through October 9. Register here: https://openspacetrust.org/event/representation-matters-film-festival/

Thank you to everyone who made this night so special. Here’s to more stories, more voices and an outdoors where everyone belongs. 🌲💚

It can't always be the National Parks! Try out some of our favorite local public lands on this National Public Lands day! They've all got amazing things to share with you.

09/25/2026

Saturday is National Public Lands Day and public lands aren’t just national parks. They’re the municipal parks, local trails, and green spaces we access every day. Anything owned/managed by a government agency is public land and public lands belong to YOU!

These amazing lands not only benefit you but also benefit the animals that call those spaces home. Places like:

📍Bair Island
📍Purisima Creek Redwoods
📍Big Basin
📍Coyote Valley
📍Windy Hill

Visiting these beautiful spaces is just the beginning. Pick up an identification book and learn about the native plants around you. Go birding in your local park.

Volunteer with us and pull invasive weeds, or join a bioblitz and become a citizen scientist! No matter what you do, go enjoy your time outside! 🚣‍♂️

The autumn equinox is at 5:05 pm tonight. Quiet moments, shorter days, and transformation are ahead.

Deciduous trees begin to pull the energy from their leaves and store the nutrients elsewhere to save energy through winter. They enter a period of dormancy until warmer weather and longer days arrive.

Be a tree. Allow yourself some time to relax.

Did you know...

🐣 Seagulls grow rapidly and don't emerge from their nests until almost fully grown!

🍃 Leaves of 3? Let them be! Poison oak turns red and shiny in the summer but can cause a rash all year long. In the winter they lose their leaves, but for those especially sensitive even the woody stems can still cause a reaction.

🐝 Did you know that our native bees are proven to be more effective and efficient at pollinating than the honey bee? In fact, the National Sustainable Agriculture Information Service, found that pollinating an acre of apples requires 60,000-120,000 honey bees; the same area can be pollinated by 250-750 mason bees.

🌳 A lot of what we have learned about seasons does not reflect a lot of how the world works. The more you learn about your local landscape the more the seasons reveal themselves to you. California has different blooming flowers year long that provide food for many creatures. Different migrating birds visit here in the fall and winter and help signify the changing seasons. Take a closer look, you'll see how fascinating our seasons are!

🐿️ Ground squirrels are highly underrated. Not only do they create dens for a multitude of species, they also aerate soil, help with water retention in the ground, and are a great food source for many flashier species different raptors, coyotes, and foxes.
