Rocky Mountain National Park: Why are there so many brown trees? The Mountain Pine Beetle is one of several common, native insects that challenge western pine forests. Drought conditions, mild winters, dwarf mistletoe infestations, dense late seral mature forest stands, and a lack of wildlife fires have contributed to the outbreak.
