Notice of release of fanny germplasm, carmel germplasm, and Bonneville germplasm Searls’ prairie clover

Publications Posted on: October 02, 2019
Three natural-track selected germplasms of Searls’ prairie clover (Dalea searlsiae (A. Gray) Barneby [Fabaceae]) have been released by the USDA’s Agricultural Research Service (ARS) for use in revegetation and restoration of semiarid rangelands in the western US. Searls’ prairie clover is a perennial leguminous forb that is native to Utah, Nevada, Arizona, and California.

Research helps conserve and restore shrub dominated ecosystems

Science Spotlights Posted on: October 14, 2016
Two common gardens were established for big sagebrush and blackbrush at the Great Basin and Desert Experimental Ranges in Utah, respectively. The experimental areas are ideal for studies in which plants representing multiple populations of a single species are grown together in common environments. These types of studies provide a useful approach for understanding species limits.  

Mountain pine beetle attack in ponderosa pine: Comparing methods for rating susceptibility

Publications Posted on: May 12, 2016
Two empirical methods for rating susceptibility of mountain pine beetle attack in ponderosa pine were evaluated. The methods were compared to stand data modeled to objectively rate each sampled stand for susceptibly to bark-beetle attack.

Mechanisms for maintenance of dominance in a nonclonal desert shrub

Publications Posted on: January 12, 2016
Blackbrush (Coleogyne ramosissima: Rosaceae) is a slow-growing, non-clonal shrub that is regionally dominant on xeric, shallow soils in the North American Mojave Desert-Great Basin transition zone and southern Colorado Plateau. Blackbrush seed production is concentrated in mast years, and most seeds are cached and later consumed by heteromyid rodents.

Drought and piñon-juniper woodlands: Changing fuel loads from tree mortality

Projects Posted on: April 28, 2015
The Colorado Plateau and Southern Great Plains continue to experience frequent droughts and high temperatures. On-going research examines whether even drought tolerant junipers may succumb to increased aridity and begin dying at increased rates, which could significantly alter fire regimes.

Dendroecological studies in the Interior West states

Science Spotlights Posted on: April 13, 2015
Tree-ring studies are used for a wide variety of purposes, including the reconstruction of past climate. In 2009, the Interior West Forest Inventory and Analysis program started a project to inventory and archive approximately 11,000 increment cores collected in most of the Interior West states during periodic inventories of the 1980s and 1990s. 

Ecological adaptation of the endemic Shepherdia rotundifolia to conditions in its Colorado Plateau range

Publications Posted on: October 03, 2014
Due to limited water supplies, use of drought-tolerant species to conserve water in irrigated urban landscapes is increasingly important in the Intermountain West. The Colorado Plateau endemic shrub Shepherdia rotundifolia Parry is a potential candidate for use in sustainable urban low-water landscapes (LWLs) for its aesthetic and drought-tolerant qualities.

Influence of climate and environment on post-fire recovery of mountain big sagebrush

Publications Posted on: May 06, 2014
In arid and semi-arid landscapes around the world, wildfire plays a key role in maintaining species diversity. Dominant plant associations may depend upon particular fire regime characteristics for their persistence. Mountain shrub communities in high-elevation landscapes of the Intermountain West, USA, are strongly influenced by the post-fire recovery dynamics of the obligate-seeding shrub, mountain big sagebrush (Artemisia tridentata Nutt.

Tamarisk coalition - native riparian plant materials program

Publications Posted on: February 05, 2013
The Tamarisk Coalition (TC), a nonprofit organization dedicated to riparian restoration in the western United States, has created a Native Plant Materials Program to address the identified need for native riparian plant species for use in revegetation efforts on the Colorado Plateau.

Discovery of cryptic Armillaria solidipes genotypes within the Colorado Plateau

Publications Posted on: November 09, 2012
Armillaria solidipes (= A. ostoyae) is a root-disease pathogen that causes severe losses in growth and productivity of forest trees throughout the Northern Hemisphere. This species is genetically diverse with variable disease activities across different regions of the world. In North America, A. solidipes in the Colorado Plateau exists in drier habitats and causes more disease on hardwoods in comparison with A.
