Thamar Wherrit passed away in August 2019. You can read about her life and legacy, and a letter from her about why she chose a conservation easement to protect her land in perpetuity.
General Description – The Wherrit Easement Rainbow Ridge project supports long term private forest conservation of a 600 acre area of mixed conifer and oak forest in the Upper Sacramento River/Mount Shasta Headwaters region. A conservation easement held by CAL FIRE was placed on this property in the summer of 2018.
Located on Rainbow Ridge (an area that totals 5,000 acres), the project is located within 2 miles of the major north-south freeway in the California, Interstate 5 and the popular recreational and retirement destination city of Mt. Shasta in Northern California. As Rainbow Ridge is easily seen from the highway, adjacent to development and with fairly gentle terrain it was identified by multiple agencies, conservation organizations, landowners and the community as a highly strategic area in need of immediate conservation.
The Wherrit Tract has been managed as both a working forest and a haven for wildlife for generations. The conservation easement over this tract permanently protects this highly developable and scenic property currently managed under an approved Non-Industrial Timber Harvest Plan (NTMP). Late owner, Thamar Wherrit, provided a stewardship model for permanent forest conservation for both non-industrial landowners along Rainbow Ridge and for others along the I-5 corridor.

Opportunities – The project area is managed as a non-industrial private forest, yielding sawlogs (and economic benefits) for processing at local wood processing facilities. Habitats for wildlife are enhanced and protected as part of the overall scheme. In 2025, SLT received funding from the Point Blue Conservation Science Roots project to support these efforts. Water flowing from the project area provides instream benefits and downstream water for agricultural and domestic uses. Hazardous fuels reduction work reduces unwanted wildfire effects in the project area and neighboring ownerships. There are also limited non-motorized recreational opportunities for future development of a public trail following the top of Rainbow Ridge.
Resources At Risk – With the establishment of an easement, aesthetic views of Rainbow Ridge from Mt. Shasta and I5 are maintained as a forested viewshed. Residential development and industrial timber harvest are precluded. Wildlife habitat will be maintained and enhanced. This is especially important since this project is adjacent to National Forest lands managed as Late Successional Reserve for northern spotted owls and other old-growth dependent species.
