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.

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).

Mortality and flowering of Great Basin perennial forbs after experimental burning: Implications for wild bees

Publications Posted on: April 09, 2019
The fates of native bee communities in the Great Basin sagebrush steppe are linked with the susceptibilities of their floral hosts to increasingly frequent wildfires. Postfire survival and subsequent flowering of six prevalent perennial wildflowers representing five families were quantified across a range of realistic fire severities created using a calibrated propane burn barrel.

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.

Identifying old trees to inform ecological restoration in montane forests of the central Rocky Mountains, USA

Publications Posted on: April 05, 2019
Old trees (defined here as ≥150 years old) can be rare in many forests because of past timber harvest, uncharacteristically severe wildfires, and - increasingly - climate change. Old trees provide unique structural, ecological, scientific, and aesthetic values missing in forests containing only younger trees.

Seedling native species increases resistance to annual grass invasion following prescribed burning of semiarid woodlands

Publications Posted on: March 27, 2019
Exotic grass invasions are often facilitated by disturbances, which provide opportunities for invasion by releasing pulses of resources available to invaders. Where disturbances such as prescribed fire are used as a management tool, there is a pressing need to identify ecosystem attributes associated with susceptibility to disturbance-induced invasion.

Managing wildfire for whitebark pine ecosystem restoration in western North America

Publications Posted on: December 14, 2018
Wildfire in declining whitebark pine forests can be a tool for ecosystem restoration or an ecologically harmful event. This document presents a set of possible wildfire management practices for facilitating the restoration of whitebark pine across its range inWestern North America. These management actions are designed to enhance whitebark pine resilience and health, while also being effective wildfire management measures.

Restoration treatments in a Montana ponderosa pine forest: Effects on soil physical, chemical and biological properties

Documents and Media Posted on: November 30, 2018
Low-elevation ponderosa pine ecosystems of the inland northwestern United States experienced frequent, low-severity fire that promoted open stands dominated by large diameter ponderosa pine (Pinus ponderosa). Fire exclusion has led to increased stand densities, often due to proliferation of less fire-tolerant species and an increased risk of stand-replacing wildfire.Document Type: Other Documents

Terrestrial vertebrates of mesquite bosques in southwestern North America [Chapter 11]

Publications Posted on: November 27, 2018
The major emphasis of this chapter is to address the species richness and population densities of land vertebrates in riparian mesquite bosques (woodlands). We find no single publication that lists vertebrates - amphibians, reptiles, birds, and mammals - of riparian mesquites of the Southwest lowlands. These vertebrates are listed for a few river valleys, such as the Santa Cruz River (Webb et al.

Breeding waterbirds of the Mexican portion of the Colorado River delta [Chapter 10]

Publications Posted on: November 27, 2018
Once a mighty and wild river with abundant wetlands, the section of the Colorado River flowing through Mexico has become a trickle ... whenever it flows. Most of the time since the 1960s, until recently, it did not and was completely dry. This brought tremendous changes in the "original" constitution and biological processes of the region, although they have not been fully investigated.
