With the primary goal of protecting habitat for wildlife, Open Space Authority preserves have a no-dog/pet policy, except for service animals. However, there are many amazing urban and regional parks and trails within the Santa Clara Valley, a number of them created with grants from the Open Space Authority, where you can enjoy the outdoors with your fur babies. Check out the list!

Meet the Bay checkerspot butterfly (Euphydryas editha bayensis), a federally threatened species that is the focus of ongoing research at Máyyan ‘Ooyákma – Coyote Ridge Open Space Preserve.

The cycle of nature continues, and in the winter months, water breathes life into Coyote Valley. Just before the December (2023) rainfall, the dedicated staff of the Open Space Authority installed a special “weir” at Spreckels Wetland to assist in the revitalization of a historic wetland in Coyote Valley. Keep reading to learn how this project is helping make the best use of water to benefit people, wildlife and the natural and working lands that sustain us. 

For equestrians, riding on the trail is a joyful and freeing experience. Spending time on horseback is a lot of fun, and trail rides can help strengthen your bond and build trust with your equine companion. Whether you are riding to a nearby trail, or trailering your horse to a new location, be sure to prepare to make it a safe, comfortable and enjoyable experience for all.

Fungi, in addition to having plenty of pun-potential, serves very important purposes in ecosystems. Keep reading to learn about the variety of mushrooms found in the Santa Clara Valley.

Over the 2023 summer season, volunteer Land Stewards made fantastic progress on the Open Space Authority's goal to reduce targeted populations of invasive plants throughout our managed lands. Among the many things that require persistent attention in the summertime, is an invasive plant known as stinkwort, one of the most prevalent invasive species in the region.

The Santa Clara Valley Open Space Authority (Authority) will open the 1,859-acre Máyyan ‘Ooyákma – Coyote Ridge Open Space Preserve to the public on Thursday, August 31. Five miles of new trails – including a new 3-mile segment of the Bay Area Ridge Trail, and a wide range of accessible experiences – will be open for free to hikers on a schedule that balances recreation and nature experiences with the sensitive habitat for the many species that make their home in the preserve’s rare serpentine grasslands.

Bordering Santa Clara Valley to the east is the Diablo Range, which is home to a rare population of tule elk that roam the hillsides. And August through November is a critical time for these animals, because it’s breeding, or rut season!
