Back from the brink: Framework to sustain resilience to species at risk

Science Spotlights Posted on: August 14, 2019
The Regeneration for Resilience (R4R) framework provides a decision structure to prioritize limited resources and utilize seedling planting and natural regeneration management to offer the best likelihood of success in positioning stands and landscapes to support resilience self-sustaining tree populations that are threatened by invasive pests. Effective management of forest regeneration dynamics can increase forest resilience and adaptive capacity to mitigate impacts of invasive species.

Where the desert meets the river: Investigating southwestern riparian ecosystems

Science Spotlights Posted on: August 12, 2019
Rivers and streams of the American Southwest have been heavily altered by human activity, resulting in significant changes to disturbance regimes. Riparian vegetation in arid land floodplain systems is critically important as foraging, migrating, and breeding habitat to birds and other animal species. To conserve riparian ecosystems and organisms, understanding how plants and animals are affected by disturbance processes and multiple stressors is critical. 

Using our understanding of resilience to disturbance and resistance to invasive annual grasses to target management actions in the sagebrush biome

Projects Posted on: July 30, 2019
The concepts of ecological resilience and resistance to invasive annual grasses have been used to develop an understanding of sagebrush ecosystem response to disturbances like wildfire and management actions to reduce fuels and restore native ecosystems. A multi-scale framework that uses these concepts to prioritize areas for conservation and restoration at landscape scales and to determine effective management strategies at local scales has been developed by Chambers and her colleagues. Regional SageSTEP (Sagebrush Treatment Evaluation Project) data coupled with west-wide AIM (Assessment, Inventory and Monitoring) data provide a unique opportunity to refine the predictors of resilience and resistance and extend the existing multi-scale framework effort.

Using environmental DNA sampling to monitor the invasion of nonnative Esox lucius (northern pike) in the Columbia River basin, USA

Publications Posted on: July 10, 2019
Aquatic invasive species are recognized as a global threat to conservation of native species and a cost to society. To develop effective suppression and monitoring programs for invasive species, fisheries managers require accurate, affordable, and efficient tools for invasive species detection. In the U.S.

Invasive Species Science Update (No. 11)

Publications Posted on: June 10, 2019
In this issue, we cover new research ranging from using chili powder to improve native plant restoration, searching for a link between exotic white pine blister rust and mountain pine beetle resistance in limber pine, identifying how melting arctic sea ice could open new pathways for invasive species introductions, and research into a relatively newly established biocontrol agent for rush skeletonweed.

Fine-scale environmental DNA sampling reveals climate-mediated interactions between native and invasive trout species

Publications Posted on: November 29, 2018
It is widely recognized that biotic interactions may act as important mediators of species responses to climate change. However, collecting the abiotic and biotic covariates at the resolution and extent needed to reveal these interactions from species distribution models is often prohibitively expensive and labor-intensive.

Regeneration for resilience framework to support regeneration decisions for species with populations at risk of extirpation by white pine blister rust

Publications Posted on: October 05, 2018
Natural forests are increasingly invaded by nonnative pests and pathogens that threaten host species with population extirpation and cascading ecological impacts.

Wilderness science in a time of change conference-Volume 5: Wilderness ecosystems, threats, and management; 1999 May 23-27; Missoula, MT

Publications Posted on: August 01, 2018
Forty-six papers are presented on the nature and management of threats to wilderness ecosystems. Five overview papers synthesize knowledge and research on wilderness fire, recreation impacts, livestock in wilderness, nonnative invasive plants, and wilderness air quality.

Integrating urban and national forest inventory data in support of rural-urban assessments

Publications Posted on: July 23, 2018
Due to the interest in status and trends in forest resources, many countries conduct a national forest inventory (NFI). To better understand the characteristics of woody vegetation in areas that are typically not forested, there is an increasing emphasis on urban inventory efforts where all trees both within and outside forest areas are measured.
