The NPS Alaska Region Science Strategy states that scientific data should guide management decisions for preserving NPS core values within each park (NPS 2006). In response to the NPS need for more information on their avian resources, biologists from the Alaska Natural Heritage Program (AKNHP) and NPS conducted an inventory of breeding birds within ALAG with two principal goals: 1. Use targeted river and land surveys during the breeding season to document as many bird species as possible within the Alagnak River corridor. 2. Quantify the distribution, relative abundance, and habitat associations of bird species occurring within ALAG during the breeding season.

Download Invasiveness Ranking System for Non-native Plants of Alaska Book in PDF, ePub and Kindle
Describes a ranking system used to evaluate the potential invasiveness and impacts of 113 non-native plants to natural areas in Alaska. Species are ranked by a series of questions in four broad categories: ecosystem impacts, biological attributes, distribution, and control measures. Also included is a climate screening procedure to evaluate the potential for establishment in three ecogeographic regions of Alaska [Juneau, Fairbanks, Nome].

Download Adventure Tourism Book in PDF, ePub and Kindle
This textbook presents a comprehensive overview of the environmental impacts of various types of adventure tourism and how these can be best managed. This volume follows on from the authors previous textbook – ‘Outdoor Recreation: Environmental Impacts and Management’ and continues the aim of developing a deeper understanding of how tourist numbers impact the environment and to provide practical solutions to these problems. Combining their own first-hand experience and research with extensive literature review the authors' present several popular adventure tourism destinations from across the globe, including the Arctic, the Himalayas, Africa, Australia and Scotland as case studies. Chapters cover the particular challenges faced by each region: including impacts on animals and birds; the spread of invasive plant species and diseases; trail impacts on vegetation; impacts on geological, historical and archaeological sites and pollution and waste issues. A discussion and evaluation of the possible management actions for minimising these impacts and how outdoor recreation tourists can be regulated concludes each chapter. This practical and engaging textbook will be invaluable to students and scholars of adventure tourism and outdoor recreation as well as practitioners and managers working in the field.

Download Trophic Cascades Book in PDF, ePub and Kindle
Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.
