About the Mangini Ranch Educational Preserve

Save Mount Diablo’s Mangini Ranch Educational Preserve is 207.8 acres situated between the Crystyl Ranch residential development in Concord and Lime Ridge Open Space in Walnut Creek.

The preserve includes grassland, stream canyons, blue oak woodland, chaparral, and oak savannas.

It’s home to rare species such as the northernmost stand of desert olive, rare Hospital Canyon larkspur, and threatened Alameda whipsnake. Deer, coyote, burrowing owls, kestrels, and lots of other wildlife live here too.

The preserve’s high ridgeline provides views of most of central Contra Costa County and to Marin, Sonoma, and Solano counties.

As you move away from the staging area of the preserve and into the open space along Galindo Creek and up the ridgeline, the sounds of cars and radios fade. They become birdsong and gentle breezes rustling through trees.

Here you will find you are transported into another space where senses are heightened and connecting to nature is inevitable.

Purpose of the Mangini Ranch Educational Preserve

The modern disconnection from nature has been widely documented in various studies.

According to a 2017 report, The Path Ahead, “Today kids spend less time outside than prison inmates, with the average child playing freely outside for just four to seven minutes a day.” This report notes that the average American now spends about 95 percent of their life indoors.

It reports that we are becoming an “indoor species,” which comes with consequences: “Our health and well-being may suffer. And the less we value our outdoor spaces, the less likely we are to protect them.”

These findings confirmed Richard Louv’s earlier groundbreaking documentation of “nature deficit disorder” in our young, wired generations.

Save Mount Diablo’s free public Mangini Ranch Educational Preserve affords our communities additional opportunities to connect with nature in intimate and private ways.

By facilitating these opportunities, we can further help address this serious issue of the modern disconnection from nature that currently threatens our perpetual land conservation mission.

The preserve is run via an online reservation system.

Long-time educators familiar with Save Mount Diablo owned properties have commented that these lands are ideal outdoor classrooms. They are more conducive and safe environments for learning compared to large public parks that are subject to multiple intrusions from any number of outsiders.
