In this report, we review the ecohydrology of southwestern streams and share results from our study sites along the Middle Rio Grande to describe effects of hydrological changes, wildfire, and invasions on plant communities and riparian-nesting birds. We also examine climate change projections and output from population models to gauge the future of aridland riparian ecosystems in an increasingly arid Southwest.

This guide establishes interagency prescribed fire complexity analysis standards. The analysis provides a focused, subjective assessment by qualified prescribed fire burn bosses that is evaluated and approved by Agency Administrators, and provides insight and improves understanding of the significant risks associated with prescribed fire. The analysis:
- Provides decision support that highlights the risk to values associated with prescribed fire implementation.
- Identifies the technical difficulty (complexity) of managing the risk to values.
- Informs the complexity rating determination of high, moderate, or low for a prescribed fire.
- Identifies prescribed fire plan elements that may pose special problems or concerns.

The Interagency Prescribed Fire Planning and Implementation Procedures Guide establishes national interagency standards for the planning and implementation of prescribed fire. These standards:
- Describe what is minimally acceptable for prescribed fire planning and implementation.
- Provide consistent interagency guidance, common terms and definitions, and standardized procedures.
- Make clear that firefighter and public safety is the first priority.
- Ensure that risk management is incorporated into all prescribed fire planning and implementation.
- Support safe, carefully planned, and cost-efficient prescribed fire operations.
- Support use of prescribed fire to reduce wildfire risk to communities, municipal watersheds and other values, and to benefit, protect, maintain, sustain, and enhance natural and cultural resources.
- Support use of prescribed fire to restore natural ecological processes and functions, and to achieve land-management objectives.

This work combines a comprehensive literature review with extensive smoke exposure concentration data for wildland firefighters to estimate health risks specific to wildland fire smoke. First, we conducted a literature review to identify smoke components that present the highest health hazard potential, the mechanisms of their toxicity, and reviewed epidemiological studies to identify the current gaps in knowledge about the health impacts of wildland fire smoke exposure for firefighters and the public. Next, we examined wildland firefighter exposures, explored predictors of smoke exposures to determine factors influencing smoke exposure for wildland firefighters and estimated exposure to air pollutants using carbon monoxide (CO) as an indicator pollutant. Lastly, we estimated disease risk in wildland firefighters for exposure to particulate matter from smoke using firefighter specific breathing rates with existing exposure response relationship information for risk of lung cancer, ischemic heart disease and cardiovascular disease from cigarette smoking, which produces particulate matter with a similar size range.

Conditions such as dense vegetation and drought have resulted in more severe wildland fires in recent years, and some communities are experiencing the devastating effects of these fires. Federal agencies can collaborate with nonfederal stakeholders to reduce the risk of wildland fires. This is a key aspect of the National Cohesive Wildland Fire Management Strategy. The Government Accountability Office recommends that federal agencies work with the Wildland Fire Leadership Council—which provides oversight and leadership for the strategy—to develop measures to assess progress toward achieving the strategy’s goals.

The CONSERVATION EFFORTS DATABASE (CED) was codeveloped by the U.S. Fish and Wildlife Service (USFWS), the U.S. Geological Survey (USGS), and the Great Northern Landscape Conservation Cooperative (GNLCC):
- USFWS provided a comprehensive ecological assessment separated by threats and efforts, and database structure based on user needs.
- USGS provided database and website design expertise building off of the Land Treatment Digital Library.
- GNLCC provided ecological, database, and GIS expertise, greatly enhancing CED capabilities.
Many state and federal partners provided input and feedback, ranging from design recommendations to policy sideboards, ensuring the CED has broad applicability and interoperability.

Researchers developed landscape-directed dispersal simulations and tested a series of replicates that emulate independent empirical datasets for greater sage-grouse and eastern fox snake. The study helps establish methods for using liner mixed models to identify the features underlying patterns of dispersal across a variety of landscapes.
