Microclimate An Alternative To Tree Vigor As A Basis For Mountain Pine Beetle Infestations PDF Download

Excerpt from Microclimate and Mountain Pine Beetles in Two Ponderosa Pine Stands in the Black Hills Infestations of mountain pine beetles (dendroctonus ponderosae Hopkins) may be common in unthinned pine stands but are uncommon in thinned stands. Subtle differences in the biotic and abiotic stand conditions may account for the numbers of beetle attacked trees in the two types of stands. The abiotic conditions, generally referred to as microclimate, are thought to play an important role. Epidemics of the mountain pine beetle (mpb) commonly develop in relatively unmanaged stands of pure ponderosa pine (pinus ponderosa Lawson) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
