This study compared historical and prescribed fire regimes for different regions in the United States and synthesized literature on season of prescribed burning. In regions and vegetation types where considerable differences in fuel consumption exist among burning seasons, the effects of prescribed fire season appears to be driven more by fire-intensity differences among seasons than by phenology. Where fuel consumption differs little among burning seasons, the effect of phenology or growth stage of organisms is often more apparent.
This document represents a synthesis of existing knowledge on wildlife responses to fire and fire-surrogate treatments, presented in a useful, management-relevant format. Based on scoping meetings and dialogue with public lands managers from throughout the United States, we provide detailed, species-level, summary tables for project biologists and fire managers trying to anticipate the effects of fire and fire-surrogate treatments on local wildlife species.
This guide is based on vegetation and fuels data collected by Sagebrush Steppe Treatment Evaluation Project (SageSTEP) researchers at study sites in six states throughout the Great Basin for two years prior to implementing land management treatments. It is divided into four sub-guides (one sagebrush and three woodland) based on regional differences in site physiognomy and ecology: sagebrush steppe, pinyon-juniper, Utah juniper, and western juniper.

This field guide provides substantial evidence that pinon-juniper woodlands have experienced major expansion in their distribution since the late 1800s by encroaching into surrounding landscapes once dominated by shrubs and herbaceous vegetation. Both infilling and expansion affects soil resources, plant community structure and composition, water and nutrient cycles, forage production, wildlife habitat, biodiversity, and fire patterns across the landscape. Another impact is the shift from historic fire regimes to larger and more intense wildfires that are increasingly determining the future of this landscape.
This study investigated downy brome and seeded species responses to variable rates of imazapic in two plant communities (salt desert shrub and Wyoming big sagebrush). Overall, imazapic was useful for helping establish desirable perennial species, but unless downy brome is reduced below a critical threshold, favorable precipitation can return sites to pretreatment levels within two years.
The main objectives of this ecological risk assessment were to evaluate the potential ecological risks from imazapic to the health and welfare of plants and animals and their habitats and to provide risk managers with a range of generic risk estimates that vary as a function of site conditions. The categories and guidelines listed below were designed to help the BLM
determine which of the proposed alternatives evaluated in the EIS should be used on BLM lands.
This synthesis documents what is known about the history, biology, ecology, and management of western juniper. This synthesis will provide guidance for defining long-term goals, setting management priorities, and developing management plans and strategies related to western juniper. It is separated into six major sections: 1) distribution and history of woodland expansion, 2) life history and biology, 3) ecology; 4) hydrology, 5) restoration and management, and 6) management guidelines.
