On August 25, 2015 speaker Matt Germino presented on his work restoring sagebrush in the Great Basin. Shrubs are ecosystem foundation species in most of the Great Basin’s landscapes. Most of the species, including sagebrush, are poorly adapted to the changes in fire and invasive pressures that are compounded by climate change. This presentation gives an overview of challenges and opportunities regarding restoration of sagebrush and blackbrush, focusing on climate adaptation, selection of seeds and achieving seeding and planting success. Results from Great Basin LCC supported research on seed selection and planting techniques are presented.

Establishment of native plant populations on disturbed roadsides was investigated at Bryce Canyon National Park (BCNP) in relation to several revegetation and seedbed preparation techniques. In 1994, the BCNP Rim Road (2,683?2,770 m elevation) was reconstructed resulting in a 23.8-ha roadside disturbance. Revegetation comparisons included the influence of fertilizer on plant establishment and development, the success of indigenous versus commercial seed, seedling response to microsites, methods of erosion control, and shrub transplant growth and survival. Plant density, cover, and biomass were measured 1, 2, and 4 years after revegetation implementation (1995?1998). Seeded native grass cover and density were the...

FY2013The increase in large wildfires at a time when habitat for Greater Sage Grouse and other species dependent on big sagebrush has also increased has led to substantial needs for big sagebrush seeds. Significant decisions on which sagebrush seed to use and on management treatments that affect competing herb layers on the same restoration sites affect the trajectory of habitat.This project will evaluate how seed source, specifically genotype and climate-of-origin, interact with landscape-scale and replicated treatments (fencing, herbicide application, mowing, and seeding).
In 2013, the U.S. Fish and Wildlife Service (USFWS) Conservation Objectives Team (COT) identified wildfire and the associated conversion of low- to mid-elevation sagebrush (Artemisia tridentata) habitats to invasive annual grass-dominated vegetation communities as the two primary threats to the sustainability of Greater sage-grouse (Centrocercus urophasianus, hereafter GRSG) in the western portion of the species range (USFWS 2013). To facilitate the examination and evaluation of the role fire and invasive plants play in the conservation of GRSG, the USFWS solicited the assistance of the Western Association of Fish and Wildlife Agencies (WAFWA) to conduct a collaborative assessment of the conservation challenges...
