Estimating abundance of a cryptic social carnivore using spatially explicit capture-recapture

Publications Posted on: October 02, 2019
Estimating population abundance of wolves (Canis lupus) in densely forested landscapes is challenging because reduced visibility lowers the success of methods such as aerial surveys and enumeration of group size using radiotelemetry. However, regular population estimates of wolves are necessary for population monitoring and sustainable management.

Development of tools for early detection, monitoring and management of the koa wilt pathogen (Fusarium oxysporum f. sp. koae) in Hawaiíi

Publications Posted on: October 02, 2019
Koa (Acacia koa Gray) is an endemic, keystone species in Hawai’i’s forests. Koa is valuable economically (contributed $30 million to Hawai’i’s forestry industry in 2001), ecologically (habitat for many endangered birds and insects), and culturally (koa is the main wood used for making Hawaiian canoes). Mortality of koa trees due to koa wilt (caused by Fusarium oxysporum f. sp.

Complementing insect aerial surveys with satellite imagery

Science Spotlights Posted on: September 06, 2019
Forest insects kill large numbers of trees in the western United States each year. The US Forest Service monitors and quantifies tree mortality from insect outbreaks using annual aerial detection surveys. The Rocky Mountain Research Station (RMRS) is demonstrating how satellite imagery can be used to produce annual maps of tree mortality, as the Forest Service anticipates relying more on satellite imagery, a cheaper alternative to aerial detection surveys, to monitor forest health in the future.

Integration and tradeoffs [Chapter 9]

Publications Posted on: August 14, 2019
Managing for sagebrush ecosystems that are resilient to disturbance and resistant to invasive plants often requires managers to make tough decisions in the face of considerable complexity and uncertainty. The decisionmaking environment is often characterized by multiple management objectives, limited management authority and capabilities, dynamic ecosystems and plant communities, and uncertain responses to management actions.

Overview of the Science Framework [Chapter 1]

Publications Posted on: August 14, 2019
The Science Framework is part of an unprecedented conservation effort underway across 11 States in the western United States to address threats to sagebrush (Artemisia spp.) ecosystems and the species that depend on them. Sagebrush ecosystems provide a large diversity of habitats and support more than 350 species of vertebrates (Suring et al. 2005).

Test-driving a roadmap for quaking aspen restoration

Science Spotlights Posted on: July 24, 2019
Quaking aspen is the most widely distributed tree species in North America. Healthy aspen forests are highly productive and support greater biodiversity than any other upland forest type in the Intermountain West. Overall, quaking aspen has been in decline throughout much of the Region and is in need of restorative intervention.

Long-term vegetation recovery and invasive annual suppression in native and introduced postfire seeding treatments

Publications Posted on: May 16, 2019
Seed mixes used for postfire seeding in the Great Basin are often selected on the basis of short-term rehabilitation objectives, such as ability to rapidly establish and suppress invasive exotic annuals (e.g., cheatgrass, Bromus tectorum L.). Longer-term considerations are also important, including whether seeded plants persist, continue to suppress invasives, and promote recovery of desired vegetation.

Guidelines for aspen restoration in Utah with applicability to the Intermountain West

Publications Posted on: May 07, 2019
As highly productive and biologically diverse communities, healthy quaking aspen (Populus tremuloides; hereafter aspen) forests provide a wide range of ecosystem services across western North America. Western aspen decline during the last century has been attributed to several causes and their interactions, including altered fire regimes, drought, excessive use by domestic and wild ungulates, and conifer encroachment.

Science framework for conservation and restoration of the sagebrush biome: Linking the Department of the Interior’s Integrated Rangeland Fire Management Strategy to long-term strategic conservation actions. Part 2. Management applications

Publications Posted on: April 12, 2019
The Science Framework is intended to link the Department of the Interior’s Integrated Rangeland Fire Management Strategy with long-term strategic conservation and restoration actions in the sagebrush biome. The focus is on sagebrush (Artemisia spp.) ecosystems and sagebrush dependent species with an emphasis on Greater sage-grouse (Centrocercus urophasianus).
