Scientists have discovered that Great Basin bristlecone pine, which has the longest lifespan of any non-clonal organism worldwide, is highly resistance to mountain pine beetle.

Defense traits in the long-lived Great Basin bristlecone pine and resistance to the native herbivore mountain pine beetle

Mountain pine beetle (MPB, Dendroctonus ponderosae) is a significant mortality agent of Pinus, and climate-driven range expansion is occurring. Pinus defenses in recently invaded areas, including high elevations, are predicted to be lower than in areas with longer term MPB presence. MPB was recently observed in high-elevation forests of the Great Basin (GB) region, North America.

World’s oldest tree species resistant to mountain pine beetle

Science Spotlights Posted on: August 18, 2016
Climate change is altering species geographic ranges, including the mountain pine beetle which is currently found further north than any other time in recorded history. Warming temperatures have caused millions of acres of mountain pine beetle-caused tree mortality across western North America, including in high elevation pine ecosystems. Extensive tree mortality in high-elevation pines is troubling, as they are foundational species playing significant ecological roles and have relatively advanced age until reproduction.
