Information on the habitat requirements and effects of habitat management on Greater Sage-Grouse was summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the current range of Greater Sage-Grouse (adapted from Schroeder et al. 2004). Although birds may be observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which provides the fundamental components or keys to management for the species. A section on breeding range outlines the current breeding distribution of the species in North America. The suitable habitat section describes the breeding habitat and occasionally microhabitat characteristics of the species. Details on habitat and microhabitat requirements often provide clues to how a species will respond to a particular management practice. A table near the end of the account complements the section on suitable habitat, and lists the specific habitat characteristics for the species by individual studies. A special section on prey habitat is included for those predatory species that have more specific prey requirements. The area requirements section provides details on territory and home range sizes, minimum area requirements, and the effects of patch size, edges, and other landscape and habitat features on abundance and productivity. It may be futile to manage a small block of suitable habitat for a species that has minimum area requirements that are larger than the area being managed. The Brown-headed Cowbird (Molothrus ater) is an obligate brood parasite of many grassland birds. The section on cowbird brood parasitism summarizes rates of cowbird parasitism, host responses to parasitism, and factors that influence parasitism, such as nest concealment and host density. The impact of management depends, in part, upon a species’ nesting phenology and biology. The section on breeding-season phenology and site fidelity includes details on spring arrival and fall departure for migratory populations, peak breeding periods, the tendency to renest after nest failure or success, and the propensity to return to a previous breeding site. The duration and timing of breeding varies among regions and years. Species’ response to management summarizes the current knowledge and major findings in the literature on the effects of different management practices on the species. The section on management recommendations complements the previous section and summarizes specific recommendations for habitat management provided in the literature. If management recommendations differ in different portions of the species’ breeding range, recommendations are given separately by region. The literature cited contains references to published and unpublished literature on the management effects and habitat requirements of the species--Page [iii].

Following the destruction of 95% of meadows during the twentieth century, there is an urgent need to understand what little unspoiled habitat remains in order to plan the management and restoration of existing sites, as well as re-creating future grassland habitats. This book is a much-needed guide to grassland restoration and management. Providing a thorough overview of recent research on grassland restoration and its implications for practical grassland restoration and management, it introduces grassland communities and the wildlife they support, including examples of species of conservation concern, and considers the management of semi-natural grassland habitats with particular emphasis on drier grassland habitats. Chapters cover: - Grassland character and communities - Introduction to grassland wildlife - Managing semi-natural grassland - Grassland restoration – threats and challenges - Opportunities in grassland restoration - Plant material for grassland restoration - Defining success in grassland restoration. A variety of management techniques are examined, including soil amendment, cultivation, harvesting and maintenance in creating suitable conditions for the successful restoration of species-rich grasslands. It is essential reading for conservationists, site owners or managers, practitioners, conservation organizations and students of ecological restoration with an interest in the creation of new grassland habitats, the restoration of semi-natural grassland, as well as the continuing management of semi-natural (unimproved) grassland communities.
