In this study, we conducted a field and data synthesis of nine years of annual plant communities occurring below perennial plants the National Park Service (NPS) had outplanted in 2008. At 30 sites disturbed by road construction and that were revegetated by NPS, we measured annual and perennial plants in 2009 (one year after nursery-grown perennials were outplanted at the sites), 2010, 2011, and 2017 (nine years after restoration). We also made these same measurements below vertical mulch structures.

In this study, researchers measured vegetation structure and fuel moisture (pre-burn), weather conditions, belowground heat dosages, and peak temperatures (during the burn), and burn severities and unburned refugia (post-burn) for paired morning and afternoon prescribed burns at each of ten prairie sites throughout the south Puget Sound in 2014.

This working paper describes how Air Resource Advisors use smoke modeling and monitoring tools to build a toolkit for fire managers and to improve public communication.

This represents the first phase of a project investigating policies that limit managers’ ability to conduct prescribed fire on US Forest Service and Bureau of Land Management (BLM) lands in the 11 Western states. The goals for this phase of our work were to understand the extent to which various policies are limiting prescribed fire programs, strategies to maintain and increase prescribed fire activities, and opportunities for improving policies or policy implementation. To understand the diversity of challenges faced and strategies in use across the West, we conducted a legal analysis of the laws and policies that affect prescribed fire programs on Forest Service and BLM lands (available online at http://ewp.uoregon.edu/publications/working) and approximately 60 interviews with land managers, air regulators, state agency partners, and several NGO partners.

Decades of overgrazing and wildfire suppression have let juniper trees grow large and spread far across sagebrush country, reducing habitat for sage grouse and other wildlife, and creating conditions for catastrophic wildfires.
In areas where fire is no longer a safe treatment, many land managers are stepping up to fill the role once played by wildfire.

Wildfires are far more likely to result in harmful air quality and public health impacts than prescribed fires because they are unplanned and typically are much larger. Wildfires also last longer, and burn and consume (on average) more vegetation per acre than prescribed fires.

This brief presents the following findings:
- Overall, mulching treatments in three Colorado conifer forest types promoted denser and more diverse native understory plant communities, particularly over the longer-term.
- The positive effect of mulching on understory plants was largely driven by the response of herbaceous plants; shrubs showed little response to mulching treatments.
- Exotic plants tended to be more common in mulched stands than in untreated stands.
- While understory plants in mulched stands could be heavily suppressed in localized areas where mulch contributed to a deep forest floor, these areas were rare.

This technical note provides conservation practitioners with information on simple yet effective “Zeedyk” restoration techniques. The emphasis here is on structures that can be built by hand to address shallow headcuts or small incised channels (< 4 ft deep) impacting meadows and low-to-moderate gradient (< 3% slope) intermittent/ephemeral drainages in sagebrush rangelands. The note provides examples and lessons learned from partners in the Gunnison Climate Working Group who have been implementing a landscape-scale project using these techniques in the Upper Gunnison River Basin, Colorado. The note provides information and references to help practitioners identify opportunities, prioritize treatments, and design projects in similar watersheds across the West.

Pinyon jays present both a conservation challenge and a paradox. While the species has declined, its preferred habitat (pinyon-juniper woodlands) has expanded, and in some areas to a large extent. It seems that population declines are not a function of reductions in habitat amount, but are related to changes in habitat quality. Up to now research on the species has been paltry,
and so details about the trend have only recently begun to surface.

Recently published research can help land managers to identify important hubs and pathways of genetic connectivity for greater sage-grouse. This knowledge can be used in evaluating proposed development or management actions in terms of how they could disrupt, protect or restore critical places of conservation for greater sage-grouse habitat. The genetic evaluation technique, combined with mapping technology, can be used to evaluate land management decisions in terms of their effect on more than 350 species that live in North American sagebrush habitat.
