How to Protect Old Trees When Reintroducing Fire: Research Brief

How to Protect Old Trees When Reintroducing Fire: Research Brief

This brief is based on a synthesis that covers recent research documenting effects of introducing fire in fire suppressed forests, provides necessary background information to understand the breadth of the problem, provides realistic management solutions to reduce impacts and defines monitoring techniques to identify treatment effects.

Where the WUI is: Implications for wildfire mitigation and outreach communities: Research Brief

Where the WUI is: Implications for wildfire mitigation and outreach communities: Research Brief

The WUI is often synonymous with fire risk to buildings, but this research suggests that this is not the case in all fire-prone states. While fire outreach was often present near areas where buildings are destroyed by wildfire, many communities are established after major fires.

Non-Native Plants, Fuels, and Desert Revegetation: Research Brief

Non-Native Plants, Fuels, and Desert Revegetation: Research Brief

To revegetate disturbed desert lands, practitioners often reestablish fertile islands as a first step in restoring native plants and associated fauna on disturbed desert sites. This research brief discusses the pros and cons of this approach considering native and non-native species.

Chaparral Bird Communities Harmed by Shrub Removal: Research Brief

Chaparral Bird Communities Harmed by Shrub Removal: Research Brief

To help managers make science-based decisions that incorporate wildlife information, this study experimentally compared the effects of two pre-fire vegetation reduction treatments (prescribed burning and shrub mastication) on the chaparral bird community.

Rapid growth of the US wildland-urban interface raises wildfire risk: Research Article

Rapid growth of the US wildland-urban interface raises wildfire risk: Research Article

Abstract
The wildland-urban interface (WUI) is the area where houses and wildland vegetation meet or intermingle, and where wildfire problems are most pronounced. Here we report that the WUI in the United States grew rapidly from 1990 to 2010 in terms of both number of new houses (from 30.8 to 43.4 million; 41% growth) and land area (from 581,000 to 770,000 km2; 33% growth), making it the fastest-growing land use type in the conterminous United States. The vast majority of new WUI areas were the result of new housing (97%), not related to an increase in wildland vegetation. Within the perimeter of recent wildfires (1990–2015), there were 286,000 houses in 2010, compared with 177,000 in 1990. Furthermore, WUI growth often results in more wildfire ignitions, putting more lives and houses at risk. Wildfire problems will not abate if recent housing growth trends continue.

Human Presence Diminishes the Importance of Climate in Determining U.S. Fire Activity: Research Brief

Human Presence Diminishes the Importance of Climate in Determining U.S. Fire Activity: Research Brief

In a study published in the Proceedings of the National Academy of Sciences, researchers with the Conservation Biology Institute and the U.S. Geological Survey showed that, across the U.S. on landscapes dominated by humans, climate has played a relatively small role in determining wildfire activity.

Effects of Two Kinds of Fuel Treatments and Their Season after Ten Years in Northern CA Chaparral:Research Brief

Effects of Two Kinds of Fuel Treatments and Their Season after Ten Years in Northern CA Chaparral:Research Brief

This brief describes potential effects of two fuel treatment types for Northern California chaparral. Different scenarios involving prescribed fire, mastication and season (fall, winter, or spring) were explored to determine effects on chaparral and findings include recommendations on when and how to use treatments where necessary.

Evolution and Biogeography of Epicormic Resprouting: Research Brief

Evolution and Biogeography of Epicormic Resprouting: Research Brief

This brief describes the advantages and evolution of postfire epicormic resprouting, where trees resprout from the trunk or stem of trees. This form of resprouting is more rare than resprouting from the base of plants and occurs in Australia and South Africa, as well as in California, the Mediterranean Basin and the Canary Islands in the northern hemisphere.
