Modeling black bear-vehicle collision zones in Yosemite National Park

High black bear-vehicle collision zones in Yosemite National Park are characterized by low visibility, steep shoulder slopes, dense understory cover, and proximity to meadows and human development. Researchers analyzed 17 years of collision data (1995–2011) using GIS mapping to segment roads into 1 km sections, measuring habitat and road variables. Logistic regression revealed that high-risk segments lacked crossing sites and visibility, contrasting with low-risk areas featuring flatter terrain, more crossings, and sparse understory. These findings provide actionable mitigation strategies to reduce bear-vehicle conflicts in protected landscapes.
