Máyyan 'Ooyákma – Coyote Ridge Open Space Preserve, Regional park in Santa Clara County, United States

Máyyan 'Ooyákma – Coyote Ridge Open Space Preserve is a 1,859-acre preserve of serpentine grassland in southern Santa Clara County, where low orange cup-shaped wildflowers and small white blooms grow among bare soil and grey rocks below a dark mountain ridge. It opened in August 2023 with 5 miles of trails, 3.9 of them part of the Bay Area Ridge Trail.

In 2015 the Santa Clara Valley Open Space Authority acquired 1,831 acres here after United Technologies Corporation agreed to donate the land, funded by partners including a $2.7 million Wildlife Conservation Board grant and $2 million from the U.S. Fish and Wildlife Service. On 27 October 2022 the preserve was renamed Máyyan 'Ooyákma – Coyote Ridge, adding the Chochenyo translation. It opened to the public in August 2023 with 5 miles of trails.

The preserve's name, Máyyan 'Ooyákma, is Chochenyo for "Coyote Ridge"; Chochenyo is the language stewarded by the Muwekma Ohlone Tribe, whose members trace ancestry to this region. The Santa Clara Valley Open Space Authority adopted the bilingual name on 27 October 2022 in partnership with the tribe, and works with the Muwekma Ohlone to raise awareness of protecting these landscapes.

The preserve opened in August 2023 with 5 miles of trails, 3.9 miles of which form part of the Bay Area Ridge Trail. Trails run through serpentine grassland where the orange wildflowers bloom close to the ground; stay on marked paths to avoid trampling rare plants and soil.

The rare serpentine soil here supports the endangered Bay checkerspot butterfly, whose larvae depend on dwarf plantain. The preserve links more than 1 million acres of habitat between the Santa Cruz Mountains and the Diablo Range, and research on its plant and animal communities continues.
