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.

Our results suggest that bird communities in piñon-juniper woodlands can be highly stable when management treatments are conducted in areas with more advanced woodland development and at the level of disturbance measured in our study.
This chapter reviews some of the conceptual and technological advancements and provide examples of how they have influenced rangeland monitoring. It then discuss implications of these developments for rangeland management and highlight what are seen as challenges and opportunities for implementing effective rangeland monitoring. It concludes with a vision for how monitoring can contribute to rangeland information needs in the future.

In this study, we present a framework for forecasting large fire occurrence – an extreme value event – and evaluating measures of uncertainties that do not rely on distributional assumptions. The statistical model presented here incorporates qualitative fire danger indices along with other location and seasonal specific explanatory variables to produce maps of forecasted probability of an ignition becoming a large fire, as well as numbers of large fires with measures of uncertainties. As an example, 6 years of fire occurrence data from the Western US were used to study the utility of two fire danger indices: the 7-Day Significant Fire Potential Outlook issued by Predictive Services in the US and the National Fire Danger Rating’s Energy Release Component. This exercise highlights the potential utility of the quantitative risk index as a real-time decision support tool that can enhance managers’ abilities to discriminate among planning areas in terms of the likelihood and range of expected significant fire events.

Resource managers often need scientific information to match their decisions (typically short-term and local) to complex, long-term, large-scale challenges such as adaptation to climate change. In such situations, the most reliable route to actionable science is coproduction, whereby managers, policy makers, scientists, and other stakeholders first identify specific decisions to be informed by science, and then jointly define the scope and context of the problem, research questions, methods, and outputs, make scientific inferences, and develop strategies for the appropriate use of science. This study presents seven recommended practices intended to help scientists, managers, funders and other stakeholders carry out a coproduction project, one recommended practice to ensure that partners learn from attempts at coproduction, and two practices to promote coproduction at a programmatic level.

This study investigated the effects of mastication and hand-thinning treatments in piñon-juniper (PJ) woodlands on ecological processes including fire, and on a wide range of species, particularly vulnerable PJ obligate birds. Treatments drove major, persistent ecological shifts relative to controls. Tree cover and canopy fuels were reduced; concomitantly, down woody surface fuels, forb, and grass cover increased. Treatments exhibited rapid, large, and persistent increases in the frequency, richness, and cover of 20 non-native plant species including cheatgrass. Treatments substantially reduced the occupancy of piñon-juniper specialist and conifer obligate bird species.

This bulletin summarizes the evaluation of more than 40 years of satellite imagery to determine what happens when a fire burns into a previously burned area. Results from this research are helping land managers to assess whether a previous wildland fire will act as a fuel treatment based on the length of time since the previous fire and local conditions such as ecosystem type, topography, and fire weather conditions. By factoring in the ecological benefits of fire, land managers are able to manage fire in a way that fosters more resilient landscapes.

** Updated 2017 ** The Fire Behavior Field Reference Guide (FBFRG) was developed as a hands-on user tool for field going Fire Behavior Analysts (FBANs), Long Term Fire Analysts (LTANs), and other fire behavior operational personnel. The FBFRG was created by the S-590 steering committee. The guide was developed by course coordinators, coaches, and field going personnel as a reference tool and look up guide for use in training and in the field by fire behavior analysts and fire managers alike.
