Permanent Preserve

Nestled near the community of Angwin in Napa County, the Linda Falls Preserve is a 177-acre sanctuary within the Conn Creek watershed.
This protected area, owned and managed by the Land Trust, offers visitors a glimpse into one of the region’s diverse habitats, featuring a stunning waterfall, rich plant biodiversity, and varied ecosystems.
Ecological Significance
The Preserve’s elevation ranges from 810 feet, where Conn Creek exits the southern boundary, to 1,580 feet at its highest point. The volcanic substrate supports a predominantly coniferous forest interspersed with mixed chaparral. Notably, there is evidence of ecological succession, with Douglas fir forests gradually replacing oak woodlands. Dominant tree species include Douglas fir, madrone, canyon live oak, black oak, and California bay. Riparian zones along Conn Creek feature white alder, bay, and maple forests, while chaparral areas are characterized by manzanita, chamise, and live oak species.
The Preserve is home to over 132 native plant species, including 11 tree species and 32 types of shrubs. It safeguards several rare and locally uncommon plants, such as:
- Napa False Indigo (Amorpha californica var. napensis): A rare plant species endemic to the region.
- Narrow-Anthered California Brodiaea (Brodiaea californica): The Preserve hosts one of the largest known populations of this species.
- Creeping Wild Ginger (Asarum caudatum): A locally rare plant found within the Preserve.
- California Willow-Herb (Epilobium ciliatum): Another locally uncommon species protected here.
Historical Background
The Linda Falls Preserve is part of the historic La Jota Land Grant and was likely first logged in the mid-1800s. In the 2000s, parcels totaling 177 acres were generously donated to the Land Trust by owners who had previously used the area as a weekend retreat. Their contribution has ensured the permanent protection of this ecologically rich landscape.
The Waterfall
A highlight of the Preserve is Linda Falls, where Conn Creek cascades over angular volcanic boulders, creating a picturesque and serene setting. The waterfall is accessible via a 1.3-mile out-and-back trail that winds through the diverse terrain of the Preserve.
Conservation and Stewardship Efforts
The Land Trust actively manages the Linda Falls Preserve to maintain and enhance its ecological health. Ongoing efforts include forest thinning to improve forest health, reduce wildfire risk, and monitoring of plant populations and streamside habitat restoration projects. As stewards of Linda Falls Preserve, the Land Trust is committed to continuing:
- Research and Monitoring: Conducting ongoing studies to monitor the health of ecosystems and the success of restoration efforts.
- Habitat Restoration: Implementing projects to maintain and enhance the ecological health of the preserve, including riparian corridor restoration.
- Invasive Species Management: Controlling invasive species to protect native plant communities.
- Forest Health and Fuels Reduction: Managing forests to reduce future wildfire severity, increase native tree diversity, protect native understory plant communities, and maximize wildlife habitat values.
Public Access and Engagement
The Linda Falls Preserve is open to the public, with exceptions. The Land Trust offers guided hikes, and hosts volunteer workdays on the Preserve, allowing visitors to experience its natural beauty while protecting its sensitive habitats. These hikes provide educational opportunities to learn about the area’s ecology, geology, and conservation efforts. Visit our Hikes and Events page to learn more and sign up.
