“In the western US, opportunities are widespread to achieve both objectives with strategically placed proactive forest management. “As governments take action to address the escalating climate and wildfire crises, they do not need to choose between climate- and wildfire-mitigation goals,” says Kerry Metlen, senior forest scientist for The Nature Conservancy in Oregon. “The need for proactive forest management in California, New Mexico, and Arizona is particularly urgent, given that a large portion of their forested area is highly vulnerable to wildfire-caused carbon loss,” says the study’s co-author, Travis Woolley, forest ecologist for The Nature Conservancy in Arizona. It also can keep more living trees on the landscape after wildfire, to continue to capture and store carbon from the atmosphere and provide seeds for future forest. Proactive forest management can reduce the number of trees killed in wildfires by reducing excess fuels, reducing the negative impacts of a century of fire suppression and global warming. The study identifies locations where communities and agencies can consider implementing proactive forest management to reduce negative impacts from wildfires, including carbon loss. It also is key in informing our overall efforts to address the wildfire crisis facing our nation’s forests by doing the right work, in the right place, at the right time.”ĭuring a wildfire, most carbon loss occurs when litter, duff, and downed woody material is consumed by the fire-but over time, trees killed during a fire decompose, producing another source of carbon loss. USDA Forest Service Chief Randy Moore added, “This type of science collaboration strengthens our efforts to support land managers in designing and implementing effective projects with multiple benefits, making good work even better. “It also could be applied to reduce risk from wildfire to other important values such as municipal water, culturally important plants, recreation, and wildlife habitat.” “Our approach can help land management agencies plan where to invest in proactive forest treatments that simultaneously reduce wildfire-caused carbon loss and protect communities from wildfire,” says the study’s lead author, Jamie Peeler, landscape ecologist and NatureNet Postdoctoral Science Fellow with the University of Montana. Areas of overlap highlight “opportunity hot spots” where action can reduce the risk from wildfire to both carbon and communities. The trapped electron moves to the valence band and neutralizes a hole (the hole is captured by the occupied trap). The excess energy of is transferred to the crystal lattice (phonon emission). They then compared these areas to areas highlighted in the Forest Service’s Wildfire Crisis Strategy, identifying where human communities most vulnerable to wildfire. An electron from the conduction band is captured by an empty trap in the band-gap of the semiconductor. The study, a collaboration among The Nature Conservancy, University of Montana, and USDA Forest Service, evaluated where living trees and the carbon they store are at risk of burning in the future. Like positron emission, electron capture occurs for proton-rich nuclei that lie below the band of stability. By subscribing, you agree to receive email related to Lab Manager content and products.
