Abstract Background Forest and nonforest ecosystems of the western United States are experiencing major transformations in response to land-use change, climate warming, and their interactive effects with wildland fire. Some ecosystems are transitioning to persistent alternative types, hereafter called “vegetation type conversion” (VTC). VTC is one of the most pressing management issues in the southwestern US, yet current strategies to intervene and address change often use trial-and-error approaches devised after the fact. To better understand how to manage VTC, we gathered managers, scientists, and practitioners from across the southwestern US to collect their experiences with VTC challenges, management responses,...

Ecosystems respond to disturbances (such as wildfire) and changing climate in a variety of ways, including persistence, recovery, and reorganization into new combinations. Some species respond by migrating across the landscape over time, which allows them to keep up with changing climate. Many forests recover after wildfire by regenerating from seeds, and public land managers often assist these processes to help ecosystems recover. However, the success of all of these strategies depends on young plants (seedlings and saplings) surviving, often when exposed to harsh conditions following fires, including prolonged droughts, heat waves, and rising temperatures. In this project, researchers will study how well young...
