The foraging patterns of large herbivores will affect their impact on structures and functions of ecosystems and on human use of natural resources. The foraging patterns are affected by a multitude of factors, e.g., forage availability, environmental conditions, and herbivore density. Furthermore, the importance of these factors has been suggested to vary over temporal and spatial scales. The impact from large herbivores will affect the management actions to fulfil socio-political policies (e.g., regarding damage to forests) and the harvest quotas could be decided from monitoring of animal numbers and damage. However, wildlife managers are often faced with a choice of several available monitoring methods, at varying cost and precision. The aim of this thesis was to improve our understanding of: 1) factors governing the foraging patterns of large herbivores and thereby also the impact on the ecosystem; and 2) performance of survey methods in relation to monitoring cost. The study was performed in south-central Sweden, and moose (Alces alces) in boreal forest was used as a model system. The results suggest that herbivore foraging decisions are scale-dependent. The significance of moose density effects, site productivity, and diversity among forage species on the foraging pattern varied from feeding patch to landscape level. On the plant level, browsing pressure and moose preference for groups of certain species varied significantly. On the stand level, moose preference for certain habitats varied according to variation in snow conditions. Furthermore, the distribution of forage types (e.g., field and shrub layer) differed between the habitats and the browsing on the different layers of forage will therefore vary according to environmental conditions. The browsing pressure was also dependent on forage availability and herbivore density. Moose density in Sweden is mainly regulated by hunting. The hunting quotas rely on more or less accurate monitoring methods. The ability to reach management goals generally increased with monitoring effort, but a combination of two relatively inexpensive monitoring methods also produced successful management outcomes.

This groundbreaking work connects the knowledge of system function developed in ecosystem ecology with landscape ecology's knowledge of spatial structure. The book elucidates the challenges faced by ecosystem scientists working in spatially heterogeneous systems, relevant conceptual approaches used in other disciplines and in different ecosystem types, and the importance of spatial heterogeneity in conservation resource management.

Domestic and wild large mammalian herbivores occur on every continent except Antarctica. Through their browsing and grazing, they affect the structure and distribution not only of vegetation, but also of associated fauna. Consequently, the interactions between management practices and herbivore populations influence the biodiversity, structure and dynamics of ecosystems across vast expanses around the globe: signs of human activity that will be detectable for epochs to come. As a follow-up work to The Ecology of Browsing and Grazing, published in 2008, this new volume presents cutting-edge research on the behaviour, distribution, movement, and direct and indirect impacts of domestic and wild herbivores on terrestrial ecosystems. The respective chapters highlight strategic and applied research on cross-cutting issues in palaeontology and ecology, and provide concrete recommendations on the management of large herbivores to integrate production and conservation in terrestrial systems. Given its scope, the book will appeal to students, researchers and anyone interested in understanding these fascinating wild animals and how they shape the natural world.

An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.
