Across the globe, a network of national parks, nature reserves, and wilderness areas provides necessary refuge for the world’s biodiversity, and yet these spaces are themselves susceptible to the effects of climate change. As the planet warms, species may need to adjust their ranges, moving among protected areas over time to maintain similar climate conditions.

Past practices, such as fire suppression, have created densely packed forests with an overabundance of woody vegetation. Live or dead, this vegetation can fuel severe wildfire. Overcrowded growing conditions also prevent trees and other plants from obtaining sufficient nutrients, light, or water to bounce back and remain healthy following a stressful event. The warming climate further stresses vegetation and can foster tinderbox conditions on the landscape, especially under widespread persistent drought.

The Wildfire Crisis Strategy calls for ramping up forest treatments on Federal, State, Tribal, and private lands well above current levels. Public and stakeholder engagement, consultation, and collaboration are critical to successful implementation of the strategy. Best available science can inform how to improve the way we engage with communities and help us collectively determine the right treatment locations and tools.

Nonnative species can be introduced or exacerbated by fire and fuels treatments. This resource describes how this can happen and what can be done to minimize the occurrence of nonnative species on burned sites or following fuels management.

Fire can be a useful tool for promoting migrations of shade-intolerant wind dispersed species such as aspen. Aspen successfully established in burned areas far from seed sources, so managers may choose to focus attention on other species in postburn reforestation.

Assessing the geomorphic sensitivity of streams and the ecological resilience of riparian ecosystems provides the basis for understanding how they have responded to disturbances and management actions and how they are expected to respond in the future.
A collaborative group of managers and scientists led by Jeanne Chambers, research ecologist and senior scientist (emeritus) with the USDA Forest Service Rocky Mountain Research Station, and geomorphologist Jerry Miller, a professor of environmental science at Western Carolina University, developed a multiscale approach to help land managers rapidly assess watersheds and categorize them based on resilience and sensitivity to disturbance. The project was built on the long-term work of Chambers and her collaborators on Great Basin riparian ecosystems.

2020 was a record year for wildfires in recent history, though the area burned was close to estimates of pre-suppression burning. We should expect more of these types of fire seasons in the future. Much of the burning was destructive rather than restorative and impacts to humans were severe.

With narrowing and potentially non-existent opportunities during other times of year, winter may currently be the most realistic and advantageous time to conduct prescribed burns. This study evaluated the effectiveness and feasibility of winter burning to demonstrate its potential utility in mixed conifer forests.
