Evaluating vital rate contributions to greater sage‐grouse population dynamics to inform conservation

Abstract: Abstract. Species conservation efforts often use short-term studies that fail to identify the vital rates that contribute most to population growth. Although the greater sage-grouse (Centrocercus urophasianus; sage-grouse) is a candidate for protection under the U.S. Endangered Species Act, and is sometimes referred to as an umbrella species in the sagebrush (Artemisia spp.) biome of western North America, the failure of proposed management strategies to focus on key vital rates that may contribute most to ach… Show more

“…Nest success and female survival are two of the most important demographic vital rates among sage-grouse [29,44]. As management actions targeting demographics ultimately aim to influence population growth, we used a model-based approach to assess the influence of treatment effects on asymptotic population growth rate (λ).…”

“…Accounting for variation among vital rates is critical to analyses of population growth [29,44]. Therefore, we generated beta distributions (using stretched-beta distribution for clutch size) to represent the central tendency and variance of each vital rate.…”

“…Survival of adult female sage‐grouse is an important factor in determining sage‐grouse population trajectories (Taylor et al , Caudill et al , Dahlgren et al ). The average survival of radio‐marked female sage‐grouse in our study area (0.40) was lower than the average survival of female sage‐grouse translocated to the Strawberry Valley SGMA, Utah, (0.60), a sage‐grouse population that was augmented with translocations over 6 years (Baxter et al ).…”

“…To stabilize sage‐grouse populations, managers have considered the ecology of the species when implementing actions designed to mitigate the species’ conservation threats (Taylor et al , U.S. Fish and Wildlife Service [USFWS] 2013, Dahlgren et al ). Wildlife managers have also attempted to augment declining sage‐grouse populations through translocations (Reese and Connelly , Connelly et al , Baxter et al ).…”
