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.

Linking phenological indices from digital cameras in Idaho and Montana to MODIS NDVI

Publications Posted on: December 06, 2018
Digital cameras can provide a consistent view of vegetation phenology at fine spatial and temporal scales that are impractical to collect manually and are currently unobtainable by satellite and most aerial based sensors.

The Rangeland Production Monitoring Service improves rangeland management

FS News Posted on: November 19, 2018
Land managers need cost-effective unbiased monitoring and assessments of current rangeland conditions and past vegetation performance in order to improve rangeland management. 

Predicting the effects of climate change on cattle production in western U.S. rangelands

Science Spotlights Posted on: September 13, 2018
Forage availability for grazing animals has always been vulnerable to the effects of variations of weather and climate from year–to–year, with some years and decades markedly drier than others.

Managing climate change risks in rangeland ecosystems

Science Spotlights Posted on: July 21, 2017
Rangelands are ecologically diverse ecosystems in the drier parts of the United States, occupying around 25 percent of the United States land area. Rangelands provide a variety of ecosystem services, including wildlife habitat, clean water, and carbon sequestration. Rangelands also provide the opportunity for commodity products such as domestic livestock, energy (solar, and oil and gas), and small diameter wood products. Rangelands contribute to the livelihoods of thousands of people in the Great Plains and the Southwest of the United States. These livelihoods are vulnerable to climate change from both an ecological and a socioeconomic perspective. Adaptation to this changing climate will have to address ecological stress as well as the social and economic challenges. 

Incorporating hydrologic data and ecohydrologic relationships into ecological site descriptions

Publications Posted on: June 24, 2016
The purpose of this paper is to recommend a framework and methodology for incorporating hydrologic data and ecohydrologic relationships in Ecological Site Descriptions (ESDs) and thereby enhance the utility of ESDs for assessing rangelands and guiding resilience-based management strategies.

Projected use of grazed forages in the United States: 2000 to 2050: A technical document supporting the 2000 USDA Forest Service RPA Assessment

Publications Posted on: May 12, 2016
Scenario analysis techniques were used to combine projections from 35 grazed forage experts to estimate future forage demand scenarios and examine factors that are anticipated to impact the use of grazed forages in the South, North, and West Regions of the United States.

Plant Guide: Hoary tansyaster (Machaeranthera canescens)

Publications Posted on: October 07, 2015
Sunflower family (Asteraceae). Hoary tansyaster is a short-lived perennial forb with pale to dark purple flowers. Plants are 15 to 75 cm (6 to 30 in) tall with diffuse branching. Leaves are about 5 cm (2 in) long and 6 mm (0.25 in) wide, oblong or lance shaped with entire to sharply toothed margin. Flower heads have many subtending bracts that reflex away from the flower at the tip (Welsh et al., 2003).

Publications Posted on: July 27, 2015
The USDA NRCS Aberdeen Plant Materials Center (PMC) produces certified early generation seed of hoary tansyaster (Machaeranthera canescens (Pursh) A. Gray [Asteraceae]), a late summer and fall blooming forb native to the Intermountain West region. Hoary tansyaster is an excellent forb candidate for restoration efforts in arid to semiarid sites.
