Application of UAV-based methodology for census of an endangered plant species in a fragile habitat

Publications Posted on: June 14, 2019
Accurate census is essential for endangered plant management, yet lack of resources may make complete on-the-ground census difficult to achieve. Accessibility, especially for species in fragile habitats, is an added constraint.

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.

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).

Contrasting climate niches among co-occurring subdominant forbs of the sagebrush steppe

Publications Posted on: April 05, 2019
Aim: Abiotic conditions are key components that determine the distribution of species. However, co-occurring species can respond differently to the same factors, and determining which climate components are most predictive of geographic distributions is important for understanding community response to climate change.

Historical Perspectives and a New U.S. Forest Service Strategy for Fish and Aquatic Stewardship

Publications Posted on: February 22, 2019
The U.S. Forest Service has a long, rich history of helping to steward the nation's fish and aquatic resources and contributing to the broader fish and aquatic conservation and scientific community in the United States and worldwide. The agency recently updated its national strategy for fish and aquatic resource stewardship.

The phylogeography of westslope cutthroat trout

Publications Posted on: December 14, 2018
Identifying units of conservation of aquatic species is fundamental to informed natural resources science and management. We used a combination of mitochondrial and nuclear molecular methods to identify potential units of conservation of Westslope Cutthroat Trout Oncorhynchus clarkii lewisi, a taxon native to montane river basins of the northwestern United States and southwestern Canada.

Hierarchical multi-population viability analysis

Publications Posted on: December 07, 2018
Population viability analysis (PVA) uses concepts from theoretical ecology to provide a powerful tool for quantitative estimates of population dynamics and extinction risks. However, conventional statistical PVA requires long-term data from every population of interest, whereas many species of concern exist in multiple isolated populations that are only monitored occasionally.

Breeding and genetic resources of five-needle pines: Growth, adaptability, and pest resistance

Publications Posted on: August 01, 2018
This volume presents 29 overview and research papers on the breeding, genetic variation, genecology, gene conservation, and pest resistance of five-needle pines (Pinus L. subgenus Strobus Lemm.) from throughout the world. Overview papers provide information on past and present research as well as future needs for research on white pines from North America, Europe, and Asia.

Ponderosa pine ecosystems restoration and conservation: steps toward stewardship; 2000 April 25-27; Flagstaff, AZ

Publications Posted on: August 01, 2018
This volume is divided into three sections: (1) Ecological, Biological, and Physical Science; (2) Social and Cultural; and (3) Economics and Utilization. Effective ecological restoration requires a combination of science and management.

Managing emerging threats to spotted owls

Publications Posted on: May 10, 2018
The 3 spotted owl (Strix occidentalis) subspecies in North America (i.e., northern spotted owl [S. o. caurina], California spotted owl [S. o. occidentalis], Mexican spotted owl [S. o. lucida]) have all experienced population declines over the past century due to habitat loss and fragmentation from logging.
