Sierra Ancha Experimental Forest Vegetation Mapping Project

Projects Posted on: March 08, 2019
The Sierra Ancha Experimental Forest (SAEF) Vegetation Mapping Project uses unmanned aerial vehicles (UAVs) to create highly detailed vegetation maps using Structure From Motion technology.  These maps are then used to overlay historical vegetation maps made nearly 100 years ago to determine how vegetation has changed over the last century.

Effects and interactions of fire, logging, and grazing

Publications Posted on: August 01, 2018
In this chapter, we summarize current knowledge about the effects of fire, logging, and grazing on coniferous forest birds and their habitats. We critically review the results of studies evaluating how these individual factors influence bird numbers, species diversity, nesting success, and habitat use in ponderosa pine forests.

Summary (Songbird ecology in southwestern ponderosa pine forests: A literature review)

Publications Posted on: August 01, 2018
Most ornithological studies in Southwestern ponderosa pine forests have yielded results that are applicable only to the specific location and particular conditions of the study areas (for example, Green 1979 and Hurlbert 1984).

Climate change vulnerability assessment of forests in the Southwest USA

Publications Posted on: July 19, 2017
Climate change effects are already apparent in some Southwestern US forests and are expected to intensify in the coming decades, via direct (temperature, precipitation) and indirect (fire, pests, pathogens) stressors.

Riparian trees and aridland streams of the southwestern United States: An assessment of the past, present, and future

Publications Posted on: September 28, 2016
Riparian ecosystems are vital components of aridlands within the southwestern United States. Historically, surface flows influenced population dynamics of native riparian trees. Many southwestern streams has been altered by regulation, however, and will be further affected by greenhouse warming.

Co-producing landscape scale vulnerability assessments

Science Spotlights Posted on: August 17, 2016
Successful management of natural and cultural resources needs to account for increasing stress due to climate change, wildfire, and anthropogenic disturbance and requires collaborative processes to identify effective strategies at landscape scales. Recognizing this need, the Southern Rockies Landscape Conservation Cooperative (SRLCC) implemented a landscape conservation design framework to develop data and tools for use during land management planning, with relevance to multiple stakeholder groups. Rocky Mountain Research Station (RMRS) scientists partnered with the SRLCC to provide expertise and analytical data products to use towards this effort.

Contemporary human use of southwestern ponderosa pine forests

Publications Posted on: May 12, 2016
The ponderosa pine forests of the Southwest provide land, resources, products, and recreational opportunities for both urban and rural communities of the region and the nation. These human uses and activities affect resident and migratory bird populations in both negative and positive ways.

Status, ecology, and conservation of the southwestern willow flycatcher

Publications Posted on: May 12, 2016
This publication was prepared in response to a need expressed by southwestern agencies and organizations for a comprehensive assessment of the population status, history, biology, ecology, habitats, threats, and conservation of the southwestern willow flycatcher (Empidonax traillii extimus). The southwestern willow flycatcher was federally listed as an Endangered subspecies in 1995.

Assessment of native species and ungulate grazing in the Southwest: Terrestrial wildlife

Publications Posted on: May 12, 2016
Range managers in the Southwestern States are increasingly being required to develop management strategies that take into consideration the conservation of wildlife populations. However, information on many aspects of the fundamental biology and impacts of grazing on individual species is still lacking in the scientific and government literature.
