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.

Tree-ring reconstruction of the level of Great Salt Lake, USA

Publications Posted on: September 12, 2014
Utah's Great Salt Lake (GSL) is a closed-basin remnant of the larger Pleistocene-age Lake Bonneville. The modern instrumental record of the GSL-level (i.e. elevation) change is strongly modulated by Pacific Ocean coupled ocean/atmospheric oscillations at low frequency, and therefore reflects the decadalscale wet/dry cycles that characterize the region.

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.

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

Publications Posted on: September 19, 2013
Annual grass invasion in the Great Basin has increased fire size, frequency and severity. Post-fire restoration to provide functional native plant communities is critical to improve resistance to weed invasion. Our ability to successfully re-establish mixtures of native grasses, forbs and shrubs, however, is limited.

Plant establishment and soil microenvironments in Utah juniper masticated woodlands

Publications Posted on: September 19, 2013
Juniper (Juniperus spp.) encroachment into sagebrush (Artemisia spp.) and bunchgrass communities has reduced understory plant cover and allowed juniper trees to dominate millions of hectares of semiarid rangelands. Trees are mechanically masticated or shredded to decrease wildfire potential and increase desirable understory plant cover.
