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. 

During the first week of December 2023, nearly 100 sixth and seventh grade students took a field trip to the Pajaro River Agricultural Preserve to help kickstart the restoration of a riparian forest. Over the course of the day, the students from the Indigo Program at the Oak Grove School District in San José planted roughly 200 native trees, shrubs, and forbs. By restoring important riparian habitat, this project promotes biodiversity as it provides for native wildlife and creates long-lost creekside habitat along a degraded stretch of the Pajaro River.

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.

David Mauk, Natural Resource Technician at the Open Space Authority, has been a lifelong nature lover, so it only makes sense that he works every day to protect wildlife and the places where wildlife live here in the Santa Clara Valley.

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!
