The closures primarily affect hikers, bicyclists, and equestrians who frequent the park's trails. The high clay content in the soil can make trails dangerously slippery, increasing the risk of accidents. Additionally, the park's closure during Red Flag Warnings is a precautionary measure to mitigate the risk of wildfires, which can pose severe threats to both visitors and the surrounding environment. These closures also help preserve the integrity of the trails, preventing damage caused by use during adverse conditions.
