The INL Ecohydrology Experiment uses irrigation to simulate increased winter or summer precipitation. Treatments include a doubling of annual precipitation added in summer (four 50-mm events) or in winter (two 100-mm events added), and non-irrigated control plots. Standard USDA species abbreviations are used.
The loss of big sagebrush (Artemisia tridentata Nutt.) on sites disturbed by fire has motivated restoration seeding and planting efforts. However, the resulting sagebrush establishment is often lower than desired, especially in dry areas. Sagebrush establishment may be increased by addressing factors such as seed source and condition or management of the plant community. We assessed initial establishment of seeded sagebrush and four populations of small outplants (from different geographies, climates, and cytotypes) and small sagebrush outplants in an early seral community where mowing, herbicide, and seeding of other native plants had been experimentally applied. No emergence of seeded sagebrush was detected. Mowing...

To test experimental warming effects, we used and enhanced the Snake River Plain (SRP) Warming Experiment. At Birds of Prey National Conservation Area (BOP NCA), a warming frame and control plot pair were established at five locations along a 4 km distance at 3000’ ASL on loam soils with a mosaic of cheatgrass (Bromus tectorum), Sandberg’s bluegrass (Poa secunda), and biotic soil crusts. This area is relatively disturbed and has high abundances of exotic annual grasses or naturalized restoration grasses. Plot sizes were 2.4 x 2.4 m and were installed in fall 2012. At 4800’ ASL on rocky loam soils in Hollister, five frames were arrayed with paired control plots across a 2 km transect at 4900’ ASL in a Wyoming Big...

We evaluated sagebrush on 24 post-fire seeding sites encompassing >50,000 acres on the Snake River Plain in the Northern Great Basin, specifically in southwest Idaho. Sites were initially identified using the Land Treatment Digital Library (LTDL; http://greatbasin.wr.usgs.gov/ltdl/; and Inciweb fire information (http://inciweb.nwcg.gov/) websites to identify seeding projects located in predominantly Wyoming big sagebrush sites (2,500 to 4,000 feet ASL; 2 sites also had A.t. vaseyana, 2 other sites had only A.t. vaseyana) that (1) had burned and were seeded within the year following fire, from 1987-2010, (2) but had not burned since, and (3) had information on seed sources. Standard USDA species abbreviations are...

FY2017This study addresses the need to develop treatments, soil amendments, and other site-preparation techniques that enhance germination, establishment, and development of healthy sagebrush communities. This study addressed the following objectives: (1) Determine whether seeded sagebrush established more frequently in fertile islands compared to burned shrub interspaces and locations where sagebrush was absent prior to the fire; (2) Determine whether the soil characteristics of sites and fertile islands within those sites influence sagebrush establishment patterns; and (3) Consider whether fertile island soil characteristics could be reporduced by manipulation post-fire soils in areas that had no pre-fire sagebrush....
