Distribution and status of seven native salmonids in the interior Columbia River basin and portions of the Klamath River and Great basins

Publications Posted on: May 15, 2015
We summarized presence, absence, current status, and potential historical distribution of seven native salmonid taxa - bull trout Salvelinus confluentus, Yellowstone cutthroat trout Oncorhynchus clarki bouvieri, westslope cutthroat trout O. c. lewisi, redband trout and steelhead O. mykiss gairdneri, stream type (age-1 migrant) chinook salmon O. tshawytscha.

Multi-century fire-regime forensics: the past as a guide for restoring landscape resilience

Projects Posted on: April 16, 2015
Multi-century fire and forest histories are reconstructed using dendrochronological techniques to assess past variation in fire regimes at various scales of time and space.

Equipment and strategies to enhance the post-wildfire establishment and persistence of Great Basin native plants

Projects Posted on: April 14, 2015
The cycle of annual weed invasion and wildfire has altered large expanses of western shrublands, disrupted ecosystem functioning, and increased wildfire size, intensity, and frequency. This research addresses reestablishment of native vegetation after fires on arid lands.

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. 

The effect of planting depth on emergence of 20 native forbs

Projects Posted on: January 22, 2015
This project studies the seedbed ecology requirements of native forbs, particularly the appropriate seeding depth in loam textured soils.

Field testing provisional seed zones for basin wildrye

Projects Posted on: January 22, 2015
In the effort to use genetically appropriate plant materials for restoration projects, provisional seed zones were developed as one method of pairing seed sources to restoration sites. 

Plant recruitment and soil microbial characteristics of rehabilitation seedings following wildfire in northern Utah

Publications Posted on: October 03, 2014
One goal of post-fire native species seeding is to increase plant community resistance to exotic weed invasions, yet few studies address the impacts of seeding on exotic annual establishment and persistence. In 2010 and 2011, we investigated the influence of seedings on exotic annuals and the underlying microbial communities. The wildfire site in northern Utah was formerly dominated by Artemisia tridentata ssp.

Flowers at the border: Plant native flowers around your yard to attract pollinators and other beneficial insects

Publications Posted on: October 03, 2014
Pollinators, including bees, moths, beetles and butterflies, are critical to the production of nearly one?third of the world's food supply. Our pollinator populations are decreasing due to a combination of factors, including habitat loss and fragmentation, overuse of pesticides, malnutrition, disease and parasites.

Gardening guide for high-desert urban landscapes of Great Basin regions in Nevada and Utah

Publications Posted on: October 03, 2014
Some Great Basin urban areas in Utah and Nevada exhibit climatic conditions that make it difficult for all but the toughest landscape plants to thrive without providing supplemental water. These areas are found at elevations from 4,000 feet to 6,000 feet in USDA cold-hardiness zones 6 and 7. Soils are often poor and gravelly, containing less than 1 percent organic matter.

Penstemons are for Great Basin gardens

Publications Posted on: October 03, 2014
Penstemons are flowering perennials much loved by the gardening public. Gardeners appreciate their diversity of flower colors that are at peak bloom in June and July, their many shapes and sizes, and their attractiveness to hummingbirds and other native pollinators. You may even have planted some in your own garden. Most people don't realize there are about 280 species of penstemon, all native to North America.
