Vineyard Mothballing
On December 2, 2025, LCWC hosted a vineyard mothballing workshop led by UC Cooperative Extension Viticulture Advisor Christopher Chen, Ph.D. The session covered research-based strategies for mothballing vineyards, with guidance on cost management, vine health, and long-term vineyard viability. Dr. Chen also shared technical resources to support growers evaluating their options.

Sustainable Winegrowing Information
According to CSWA, sustainable winegrowing is:
- Good for the environment – Sustainable winegrowing preserves natural resources, improves air and water quality, and protects ecosystems and wildlife habitat.
- Good for the community – Sustainable winegrowing helps growers and vintners be stewards of both natural and human resources, preserving open space and providing scenic landscapes.
- Good for grapes and wine – Sustainable practices require in-depth attention to detail and continuous improvement resulting in high quality California winegrapes and wine.

Lake County Viticultural Soils
The USDA Natural Resources Conservation Service maintains a soil survey of all the soils in the nation. To find the soil type(s) for a specific parcel, go to the Web Soil Survey (WSS).
Click on the big green button to begin (Start WSS). Select state and county, click View. Then, using the tools in the upper left section of the map area, zoom in or out to navigate to the parcel, then click the AOI tool to select the specific parcel. The results will identify your Area of Interest with blue hash marks; click the Soil Map tab at the top to view the various soil types by number. To the left of the map, a list will show each soil type by name and percent. Click on each soil type for more information.
For detailed information about specific Lake County soil types to assist with soil evaluation and site management, refer to the USDA’s document, Soil Survey of Lake County, California.
Emergency Preparedness: Restricted Access Program
The Lake County Restricted Access Program was established to assist commercial agricultural producers in completing critical work during emergencies to reduce significant production loss to commercial agriculture. The program consists of two steps: Step 1) the process to verify the commercial agricultural business operation, and Step 2) the verification of the critical need and issuance of a permit for temporary restricted access.
Growers are encouraged to obtain commercial agricultural verification (Step 1) well in advance of any emergencies. In most cases, this will expedite permit issuance (Step 2) during a restricted access order.
Required forms are available on the Lake County Department of Agriculture website:
Wildfire Resources
Wildfires have impacted many regions across the state of California over the past several years. Most Lake County vineyards suffered little or no damage in these fires – and in some cases even acted as a firebreak that helped to slow the spread of fires. For growers who were impacted, resources for remediation and rebuilding are available. Information is available on the Wildfire Resources page.
