There are numerous resources available to help whole communities prepare for, respond to, and recover from wildfire and other disasters. This guide presents several focused on more equitable and inclusive strategies. These resources are intended to help communities and organizations expand their work to include all those impacted by wildfire. Note that not all resources will be appropriate for all and many more resources exist than can be listed here.

It is not well understood whether desert plantings can facilitate recruitment of other natives (or mainly just non-natives), or whether facilitation changes through time as a restoration site matures. To address these uncertainties, we partnered with the National Park Service to study plant community change below planted perennials and in interspaces (areas between perennials) during 12 years (2009-2020) in Joshua Tree National Park, California, in the southern Mojave Desert.

This study uses tree cores gathered at three 4-hectare plots to make inferences about temporal aspects of tree recruitment in pine-dominated ecosystems of the California Sierra Nevada and the Sierra San Petro Martir in northwestern Mexico.

In California’s dry mixed conifer forests, increasingly large high severity wildfires threaten to convert significant areas of forested land into shrub dominated landscapes in the absence of active reforestation, including control of competing vegetation. Previous studies have found that salvage logging and other methods used to prepare a site for reforestation may reduce shrub cover after wildfire. This study investigated the effect of masticated fuel depth on shrub growth where salvage logging and mastication followed high severity wildfire.

This report highlights recent science on primary threats to persistent woodlands, identifies the role of changing climate, and highlights new efforts and approaches to develop management strategies focusing on building pinyon-juniper woodland health and climate resilience.

Many tools that identify wildfire risks and hazards across the landscape assume that all houses and properties within a community have the same level of risk. However, there are often substantial differences across properties, such as building materials and distance to overgrown vegetation. Tools that don’t account for parcel-level risk cannot provide the details necessary for informing action on private property, such as maintaining defensible space, posting a visible address sign, or hardening a structure.

Colorado State University engineers have developed a model that can predict how wildfire will impact a community, down to which buildings will burn. They say predicting damage to the built environment is essential to developing fire mitigation strategies and steps for recovery.

Wildfires burned more area on non-forested lands than forested lands over the past 20 years. This was true for all land ownerships in CONUS and the western US. Burned area increased over the 20-year time period for both non-forest and forest. Across CONUS, annual area burned was higher on non-forest than forests for 14 of the past 21 years (Fig. 1), and total area burned was almost 3,000,000 ha more in non-forest than in forest. For the western US, total burned area was almost 1,500,000 ha more in non-forest than in forest. From a federal agency perspective, approximately 74% of the burned area on Department of the Interior (DOI) lands occurred in non-forest and 78% of the burned area on US Forest Service (FS) lands occurred in the forest.

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.
