Walt Ranch

This ecologically rich Preserve supports rare and endangered species, contributes to regional biodiversity, and serves as a vital wildlife corridor—connecting oak woodlands, chaparral, and grasslands across Napa Valley’s eastern hills to promote species survival in the face of climate change and habitat fragmentation.

Ecological Significance

The Preserve encompasses diverse habitats, including oak woodlands, chaparral, and grasslands, providing sanctuary for a variety of plant and animal species. Notably, the property supports several rare and endangered species, such as:

• Narrow-Flowered California Brodiaea (Brodiaea leptandra): A species with a significant portion of its population in Napa County, including at Walt Ranch.
• Jepson’s Leptosiphon (Leptosiphon jepsonii): Another rare species protected within the preserve.

The preservation of these species contributes to the biodiversity and ecological health of the region. Additionally, the Preserve serves as a critical wildlife corridor, connecting habitats across the eastern hills of Napa Valley. This corridor enables the movement and migration of wildlife, supporting species survival and adaptation in the face of climate change and habitat fragmentation.

Historical Background

The acquisition of Walt Ranch was made possible through a combination of generous donations and grants that allowed for the purchase of this significant property. Craig and Kathryn Hall, the previous owners, donated over 25% of the property’s value. Additional funding for the purchase came through grants totaling $18 million from the State Coastal Conservancy, the Gordon and Betty Moore Foundation, and the Wildlife Conservation Board.

The permanent protection of this important property stands as a testament to the power of community collaboration in conservation. Together, we have ensured that this ecologically rich landscape will remain a refuge for wildlife and a natural treasure for all to enjoy.

The Land Trust is now focused on building a $4 million fund to pay for land stewardship and expenses of this large property, including a required management plan. A $1 million donation from the William and Inez Mabie Family Foundation has been committed to kickstart this effort.

Conservation and Stewardship Efforts

The Land Trust is committed to the long-term ecological health of this Preserve and is actively planning for its future through thoughtful, science-based research and stewardship. Environmental reviews are underway, as required by grant funding, to ensure that any future public access will be thoughtfully integrated in ways that protect sensitive habitats, rare species, and the preserve’s broader conservation values.

Stewardship efforts across the Preserve will focus on both ecological restoration and climate resilience. These include:

• Forest Health and Fuels Reduction: Strategic forest thinning, targeted grazing, and prescribed burns are planned to reduce wildfire risk and promote healthier, more diverse native plant communities.
• Invasive Species Management: Active efforts to remove and suppress invasive plants will help protect native biodiversity and maintain the ecological balance of the preserve’s grasslands, and riparian areas.
• Rare Species Restoration: The Preserve is home to several rare and endangered species. Ongoing habitat restoration work will be designed to support their survival and recovery by enhancing the conditions these sensitive species require to thrive.
• Stream and Watershed Protection: Erosion control projects will be implemented along old ranch roads to prevent sedimentation in nearby streams, protecting water quality and aquatic habitats.
• Sustainable Public Access: As part of a future vision for community engagement, plans include developing sustainable trail systems that allow for low-impact recreation while safeguarding sensitive ecological areas.

These conservation strategies are being carefully designed to uphold the Preserve’s role as a biodiversity hotspot and a crucial wildlife corridor. By blending restoration work with mindful planning for access, the Land Trust is working to ensure that this land will continue to support both people and nature—for generations to come.

Public Access and Future Plans

Access to the Preserve is currently by permission only and through guided hikes organized by the Land Trust. This approach ensures the protection of sensitive habitats and rare plants while allowing visitors to experience the preserve’s natural beauty and ecological importance. Eventually, portions of the property will be open to the public for hiking, biking, and other recreational uses. These activities will be carefully planned to ensure they align with conservation objectives and maintain the integrity of the habitats.
