Potential Impacts of Insect-Induced Harvests in the Mixed Forests of New England

摘要: Forest insects and pathogens have significant impacts on U.S. forests, annually affecting an area nearly three times that of wildfires timber harvesting combined. However, coupled with these direct effects forest are the indirect through influencing management practices, such as harvesting. In earlier study, we surveyed private woodland owners in northeastern 84% respondents indicated they intended to harvest at least one presented insect invasion scenarios. This response represents a potentially shift timing, extent, species selection Here used results from landowner survey, regional inventory data, characteristics emerald ash borer (Species: Agrilus planipennis Fairmaire, 1888) examine potential for rapidly spreading invasive alter regimes affect conditions. Our analysis suggests 25% parcels Connecticut River Watershed New England may intend borer. If continues spread its current rate within region, therefore associated occurs next decade, this could result increase frequencies, 2.6% year−1 (historically) 3.7% approximately 2030. intensities remain levels found remeasured Inventory Analysis plots, insect-initiated would removal 12%–13% total aboveground biomass. Eighty-one percent removed biomass be other than ash, creating disturbance is over twice magnitude created by alone, most valuable co-occurring vulnerable loss.
