New research provides scientific framework for conserving iconic sagebrush landscapes

FS News Posted on: April 15, 2019
An unprecedented conservation effort is underway across 11 Western states to address threats to sagebrush ecosystems and the many species that depend on them. Today, the Department of Agriculture and the Department of Interior released the Science Framework for Conservation and Restoration of the Sagebrush Biome (Part 2). The Science Framework provides a transparent, ecologically responsible approach for making policy and management decisions for sagebrush landscapes.

Is resistance to mountain pine beetle associated with genetic resistance to white pine blister rust in limber pine?

Publications Posted on: October 04, 2018
Limber pine (Pinus flexilis James) co-evolved with the mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) and is now also challenged by the non-native pathogen Cronartium ribicola (J.C. Fisch.) that causes the lethal disease white pine blister rust (WPBR). Previous research suggests that trees infected with WPBR can be preferred hosts for MPB.

Habitat fragmentation reduces genetic diversity and connectivity of the Mexican spotted owl: A simulation study using empirical resistance models

Publications Posted on: October 03, 2018
We evaluated how differences between two empirical resistance models for the same geographic area affected predictions of gene flow processes and genetic diversity for the Mexican spotted owl (Strix occidentalis lucida). The two resistance models represented the landscape under lowand high-fragmentation parameters.

Genetic resistance to Cronartium ribicola in limber pine (Pinus flexilis)

Publications Posted on: August 30, 2018
Limber pine (Pinus flexilis) is being threatened by the lethal disease white pine blister rust (WPBR) caused by the nonnative pathogen Cronartium ribicola. The types and frequencies of genetic resistance to the rust in native populations before invasion are likely to determine the potential success of restoration or proactive measures.

A conservation planning tool for Greater Sage-grouse using indices of species distribution, resilience, and resistance

Publications Posted on: July 10, 2018
Managers require quantitative yet tractable tools that identify areas for restoration yielding effective benefits for targeted wildlife species and the ecosystems they inhabit.

Sensitivity of resource selection and connectivity models to landscape definition

Publications Posted on: July 20, 2017
Context: The definition of the geospatial landscape is the underlying basis for species-habitat models, yet sensitivity of habitat use inference, predicted probability surfaces, and connectivity models to landscape definition has received little attention.

Post-fire vegetation response at the woodland-shrubland interface is mediated by the pre-fire community

Publications Posted on: July 19, 2017
Understanding the drivers of ecosystem responses to disturbance is essential for management aimed at maintaining or restoring ecosystem processes and services, especially where invasive species respond strongly to disturbance.

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

Publications Posted on: April 11, 2017
The Science Framework is intended to link the Department of the Interior’s Integrated Rangeland Fire Management Strategy with long-term strategic conservation actions in the sagebrush biome. The Science Framework provides a multiscale approach for prioritizing areas for management and determining effective management strategies within the sagebrush biome.

Conservation and restoration of the sagebrush biome

Science Spotlights Posted on: April 10, 2017
The Science Framework for Conservation and Restoration of the Sagebrush Biome (Science Framework) provides a strategic, multiscale approach for prioritizing areas for management and determining effective management strategies across the sagebrush biome.

Evaluating changes in drought resistance across California ecosystems

Science Spotlights Posted on: December 22, 2016
Using satellite imagery, this study identifies California ecosystems that are most resistant to drought. Changes in water use efficiency were used to measure ecosystem drought resistance, to improve our understanding of how ecosystems respond to water limitation.
