Strong relationships between morphological characteristics and age were found. Sagebrush mortality was estimated from stand age demographics, and seedling survival of other studies. Cover and density of naturally occurring Artemisia cana stands were measured in 10 m x 10 m plots, with stem diameter, crown diameter, canopy cover, and age measured on individuals. Models that enable the calculation of seeding or planting densities to obtain desired sagebrush cover within specific time frames are essential for restoration. Field research was conducted in Grasslands National Park (GNP), Saskatchewan, Canada.

This research focused on developing methods to improve restoration of Sage-grouse habitat by increasing establishment, growth, and survival of Silver sagebrush ( Artemisia cana Pursh), a critical component of Sage grouse habitat. Initial declines of Sage-grouse populations were likely due to habitat loss, degradation, and fragmentation, which continue to be major contributors to ongoing declines. Shelley PrussĪbstract: Populations of Greater Sage-grouse ( Centrocercus urophasianus Bonaparte hereafter Sage-grouse) have been in decline in North America for the last 100 years since 1988, the Canadian population has declined by 98%.
