The authors looked at expanding bear populations in the Lake Tahoe Basin and Western Great Basin Desert in Nevada, examining 382 bear deaths between 1997 and 2013. They found that the largest causes of mortality were vehicle collisions (160) and management removal of bears (132) due to animals breaking into people's homes and/or causing property damage, or other threats to human safety.

The authors say that by understanding the causes and consequences of mortality on bears using long-term data, wildlife managers will be able to reduce bear deaths in urban interface areas where bears could otherwise be killed more frequently.
