The findings highlight a critical vulnerability in coast redwoods, which are vital to California's biodiversity and economy. These trees serve as habitats for unique species like the wandering salamander and marbled murrelet, and their decline could disrupt these ecosystems. Additionally, redwoods contribute significantly to California's tourism industry, attracting millions of visitors annually. The inability of these trees to adapt to increasing heat could lead to long-term ecological and economic consequences, including the loss of biodiversity and reduced tourism revenue.
