What Does It Mean to Steward the Land?

Save Mount Diablo has been stewarding open space since our inception in 1971. In essence, to steward is to be responsible for the well-being of some entity. For Save Mount Diablo, stewardship means managing, protecting, and celebrating the land.

Land conservation in perpetuity is an integral part of Save Mount Diablo’s mission, and as a landowner, we have the responsibility to conserve the natural landscape. Mount Diablo and its surrounding foothills are the focus of our stewardship activities.

Why We Steward the Land

Each of Save Mount Diablo’s Properties Requires Care

To ensure open space remains open for the long run, Save Mount Diablo works with collaborating agencies to turn our lands over to public entities. Save Mount Diablo acquires land, then turns it over to park agencies.

In preparation for transferring property to the East Bay Regional Park District or Mount Diablo State Park, Save Mount Diablo stewards the land, enhancing the conservation values of the properties we purchase.

We Rely on Stewardship Volunteers

Volunteers engage in planting, watering, habitat restoration, creek cleanups, non-native plant removal, debris removal, fence building, trail construction, and other work projects. A newly acquired property may need extensive cleanup—old, deteriorating fencing is cleared away, and any debris that might have accumulated on the property is removed, returning the land to its natural state.

In some cases, fencing is added to protect creeks and ponds and help restore natural habitat. With the support of volunteers, Save Mount Diablo maintains the integrity of wildlife habitat, scenic viewsheds, waterways, and recreational corridors through land stewardship activities.

Stewardship staff and volunteers spend thousands of hours each year participating in hands-on land management activities. From monitoring properties on a monthly basis to cleaning up dump sites to re-establishing native bunchgrasses, Save Mount Diablo’s stewards perform a variety of tasks aimed at preserving natural resources on and around the mountain.

How We Steward the Land

Our Core Efforts

Property Monitoring

With property holdings of about 2,000 acres, having eyes and ears on the ground is crucial. Stewardship staff and volunteers monitor Save Mount Diablo properties on a monthly basis, informing annual work plans and overall management priorities.

Monthly monitoring reports ensure a consistent record of land stewardship and help make sure operations are consistent with our land conservation mission.

Demos and Cleanup

Whenever possible, Save Mount Diablo focuses land stewardship activities on reducing or eliminating human impacts on the landscape. Due diligence is a top priority; land acquisition and stewardship staff draft management plans soon after purchase.

Demolition of structures as well as trash and debris cleanup are included in these management plans and are employed wherever appropriate.

Fire Abatement

Stewardship staff performs fuels management activities on properties on an annual basis. Fire is a natural part of the California landscape, however, creating firebreaks along fence lines and defensible space around structures is a best management practice.

Fire prevention is one way to ensure that wildlife habitat and other natural resources are maintained on Save Mount Diablo properties and neighboring parcels.


Where appropriate, cattle grazing is employed on Save Mount Diablo properties to manage fuels and enhance grasslands. Not only do cattle keep down non-native annual grasses that are highly flammable during the summer months, they can add greatly to the species diversity, health, and vitality of California rangeland ecosystems.

Habitat Restoration

Save Mount Diablo recognizes that ecological restoration has become increasingly important for the viability of natural resources. Current development pressures threaten biodiversity and pose the highest risk in our region to rare, endemic, and sensitive species. It is our responsibility as land managers to protect and enhance our lands whenever possible.

Integrated Pest Management (IPM)

One way stewards maintain biodiversity on Save Mount Diablo lands is by targeting non-native and invasive species with an Integrated Pest Management (IPM) approach. Through a combination of monitoring and treatment methods, stewards target the most detrimental species and prioritize a chemical or mechanical strategy.

Getting Involved

We Need Boots on the Ground

With a land bank of about 2,000 acres and three stewardship staff, we depend greatly on the “boots on the ground” work that stewardship volunteers perform—including two workdays per month on rotating properties, mowing firebreaks in the spring, monthly property monitoring visits, and specific projects to steward the land.

Join an existing body of stewardship volunteers who perform a variety of tasks on Save Mount Diablo holdings, such as:

  • Our all-volunteer Stewardship Committee cares for Save Mount Diablo acquisitions, from the smallest (a few acres) to the largest (over 1,000 acres). In addition to helping to manage the land, Save Mount Diablo stewards lead hikes through our properties for interested members of the public.
  • The Diablo Restoration Team (DiRT) helps restore properties so they can be turned over to park systems for public access. Volunteers weed, water, plant, clean, and build.
  • Save Mount Diablo Trail Dogs, a group of volunteer trail-builders, works with us to create environmentally appropriate trails through our properties. Trails are designed in consultation with whichever public agency may take ownership of the land so that new trails will eventually connect with existing trail systems.

Diablo Restoration Team Workday Calendar

Our Diablo Restoration Team works to restore Save Mount Diablo properties, usually twice per month. Sign up for Diablo Restoration Team workdays on Eventbrite.
