Four MBCA board members continue to be involved in the planning and response for California’s 30x30 Project. The project was developed from Governor Newsom’s 2020 Executive Order N-82-20 which establishes a state goal of conserving 30% of California’s lands and coastal waters by 2030.

Arch McCulloch, Brian Hammer, Pat Flanagan and Gary Stiler are most concerned about some challenges in recognizing the importance and contours of the desert within the plan. "Our biggest concern is they don't acknowledge the desert as a whole, they only acknowledge a piece of it. Nor does the state acknowledge that the CA Desert sequesters 10% of the state's carbon. We want them to explore what's there," reports Flanagan.

In a February 2022 letter co-signed by MBCA, desert groups complained about "ecological fragmentation of the California desert" in an earlier version of the 30x30 plan, as Death Valley was considered part of the Sierra Nevada area and Anza Borrego was attached to the San Diego section. This issue was not corrected in the final plan (PDF).
