Technology and Trees: Increasing trust and efficiencies in forest restoration

Climate Change, Fire
With over two million acres of Arizona’s forests vulnerable to catastrophic wildfire, we must change how we manage forests to reduce this risk. Accelerating the pace and scale of forest restoration treatments to meet this challenge requires new ways of doing business. Today’s forest management requires a collaborative approach between the Forest Service, wood product industries, and organizations like The Nature Conservancy to modernize rules and regulations; test, develop, and use new technology to work smarter and faster at less cost; and forge innovative partnerships that provide the support needed for this transformation. The Nature Conservancy is developing new technology that help harvesters, the Forest Service, and stakeholders meet today’s forest restoration goals. Using satellite and 3D imagery, geographic information systems, and electronic tablets, our efforts show promise in creating efficient, less-costly methods to digitally “mark” trees, prepare sites for treatments, harvest trees, and monitor effects of treatments.

Landscape-scale forest restoration decreases vulnerability to drought mortality under climate change in southwest USA ponderosa forest
Drought is projected to increase tree mortality in many western US forests due to climate change and could result in large-scale tree die-offs, altering forest composition and ecosystem services. Tree mortality has also been found to be higher in forests with greater tree density. Southwestern US fo[…]
The Nature Conservancy, in collaboration with the Western Water Assessment and the USDA-Agricultural Research Service, has produced a snowtography handbook to support resource managers, researchers, and practitioners seeking to understand how the arrangement and density of trees, or the size and sev[…]

Tree mortality response to drought-density interactions suggests opportunities to enhance drought resistance
A future of hotter temperatures and less precipitation under climate change could increase tree mortality under drought conditions in dry forests across the western U.S., causing large-scale tree die offs. Restoration projects that reduce densities of overgrown forests can result in lower competit[…]
