This collection of essays—divided into three key categories: Risk, Culture, and Operations—daylights qualities and practices in the wildland fire service across a broad spectrum, from outdated and unwarranted to honorable and profound. We must acknowledge our current culture and its shortcomings while using its strengths to lead change.

Sage grouse and many other species rely on a range of mesic habitats—including riparian areas, wet meadows, alfalfa fields, and productive rangelands—to sustain their populations. Landscapes with the greatest uncertainty in mesic abundance and distribution support the fewest grouse.

This collection represents collective insight into how we operate and why we must alter some of our most ingrained practices and perspectives.

This report synthesizes our current knowledge on mastication as a forest management tool. We found that excavators, skid steers, and tractors can all be carrier machines and different types of vertical and horizontal cutting heads exist that can be front-end mounted or boom mounted, each with its own advantages and disadvantages. We provide a summary on the ecological effects from mastication. We found that there were several studies on plant and soil impacts, but limited information on impacts to wildlife habitat. Although costs of mastication widely vary depending on machine size, the physical setting, size and configuration of pre-treatment biomass, and operator skill, mastication does have market and non-market benefits. Depending on the management objective, if mastication is an option, then a thorough site evaluation should consider slope, nonnative species invasions, vulnerability of soils to erode or compact, and treatment costs.
Read UT Conservation Plan.
This Plan identifies strategies to address localized threats to sage-grouse populations in Utah. Those strategies include—but are not limited to—the following:
- Identify the highest-priority sage-grouse habitats and migration corridors, and protect at least 5,000 of those acres annually through conservation easements, or other mechanisms.
- Improve and increase sage-grouse seasonal habitats by 75,000 acres each year, including riparian and mesic habitats.
- Monitor sage-grouse population trends annually and, if necessary, implement adaptive management responses to ensure that priority populations remain viable and stable.
- Coordinate with local, state and federal firefighting jurisdictions to include sage-grouse habitats as a priority during pre-fire attack planning and suppression, second only to the protection of human life and property.
- Fund, support and implement critical research that supports the implementation of this Plan.
The Revegetation Equipment Catalog provides provides descriptions, applications, photos, and vendors of equipment used for seed collection and cleaning, site preparation, revegetation, and vegetation management.

This document highlights work being done to address each goal of the Seed Strategy, followed by ecoregional projects that illustrate the extent of collaborations that are underway to lay the foundation for a more comprehensive network of collectors, testers, and growers to make native plants more available across the country.
Strategy actions are centered around four major goals:
- Identifying and quantifying seed needs
- Undertaking research and improving technologies for seed production and use
- Developing tools for land managers
- Ensuring good communications

This report synthesized insights from current understanding of drought impacts at stand-to-biogeographic scales, including management options, and we identify challenges to be addressed with new research. Large stand-level shifts underway in western forests already are showing the importance of interactions involving drought, insects, and fire. Diebacks, changes in composition and structure, and shifting range limits are widely observed. Throughout the continental United States, the combination of projected large climate-induced shifts in suitable habitat from modeling studies and limited potential for the rapid migration of tree populations suggests that changing tree and forest biogeography could substantially lag habitat shifts already underway. Forest management practices can partially ameliorate drought impacts through reductions in stand density, selection of drought-tolerant species and genotypes, artificial regeneration, and the development of multistructured stands. However, silvicultural treatments also could exacerbate drought impacts unless implemented with careful attention to site and stand characteristics. Gaps in our understanding should motivate new research on the effects of interactions involving climate and other species at the stand scale and how interactions and multiple responses are represented in models. This assessment indicates that, without a stronger empirical basis for drought impacts at the stand scale, more complex models may provide limited guidance.

Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico. More than two dozen authors – most with decades of experience – review the origins of riparian science in the western United States, document what is currently known about riparian ecosystems, and project future needs. Topics are widespread and include: interactions with fire, climate change, and declining water; impacts from exotic species; unintended consequences of biological control; the role of small mammals; watershed response to beavers; watershed and riparian changes; changes below large dams; water birds of the Colorado River Delta; and terrestrial vertebrates of mesquite bosques. Appendices and references chronicle the field’s literature, authors, “riparian pioneers,” and conferences.

This synthesis presents existing information and identifies critical knowledge gaps in our understanding of seed-based aspen regeneration, in particular as it relates to flowering and seed production, as well as germination, first year growth, and survival of aspen seedlings. This information is discussed further in the context of aspen ecology and its application in both passive and active management approaches to aspen seedling regeneration and restoration.
