Pollinators—insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction—are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination.</p> <p>This report provides evidence for the decline of some pollinator species in North America, including America’s most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Most prairies exist today as fragmented landscapes, making thoughtful and vigilant management ever more important. Intended for landowners and managers dedicated to understanding and nurturing their prairies as well as farmers, ranchers, conservationists, and all those with a strong interest in grasslands, ecologist Chris Helzer’s readable and practical manual educates prairie owners and managers about grassland ecology and gives them guidelines for keeping prairies diverse, vigorous, and viable. Chapters in the first section, "Prairie Ecology," describe prairie plants and the communities they live in, the ways in which disturbance modifies plant communities, the animal and plant inhabitants that are key to prairie survival, and the importance of diversity within plant and animal communities. Chapters in the second section, "Prairie Management," explore the adaptive management process as well as guiding principles for designing management strategies, examples of successful management systems such as fire and grazing, guidance for dealing with birds and other species that have particular habitat requirements and with the invasive species that have become the most serious threat that prairie managers have to deal with, and general techniques for prairie restoration. Following the conclusion and a forward-thinking note on climate change, eight appendixes provide more information on grazing, prescribed fire, and invasive species as well as bibliographic notes, references, and national and state organizations with expertise in prairie management. Grasslands can be found throughout much of North America, and the ideas and strategies in this book apply to most of them, particularly tallgrass and mixed-grass prairies in eastern North Dakota, eastern South Dakota, eastern Nebraska, eastern Kansas, eastern Oklahoma, northwestern Missouri, northern Illinois, northwestern Indiana, Iowa, southwestern Wisconsin, and southwestern Minnesota. By presenting all the factors that promote biological diversity and thus enhance prairie communities, then incorporating these factors into a set of clear-sighted management practices, The Ecology and Management of Prairies in the Central United States presents the tools necessary to ensure that grasslands are managed in the purposeful ways essential to the continued health and survival of prairie communities.

by Cathryn H. Greenberg (Editor), Beverly S. Collins (Editor)
This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.

The Natural Communities of Georgia presents a comprehensive overview of the state’s natural landscapes, providing an ecological context to enhance understanding of this region’s natural history. Georgia boasts an impressive range of natural communities, assemblages of interacting species that have either been minimally impacted by modern human activities or have successfully recovered from them. This guide makes the case that identifying these distinctive communities and the factors that determine their distribution are central to understanding Georgia’s ecological diversity and the steps necessary for its conservation. Within Georgia’s five major ecoregions the editors identify and describe a total of sixty-six natural communities, such as the expansive salt marshes of the barrier islands in the Maritime ecoregion, the fire-driven longleaf pine woodlands of the Coastal Plain, the beautiful granite outcrops of the Piedmont, the rare prairies of the Ridge and Valley, and the diverse coves of the Blue Ridge. The description of each natural community includes Traits that make it interesting and significant Physical factors and ecological processes that determine the distribution and characteristics of each community Typical plant communities Representative or noteworthy animals Sidebars that discuss particularly interesting features With contributions from scientists who have managed, researched, and written about Georgia landscapes for decades, the guide features more than four hundred color photographs that reveal the stunning natural beauty and diversity of the state. The book also explores conservation issues, including rare or declining species, current and future threats to specific areas, and research needs, and provides land management strategies for preserving, restoring, and maintaining biotic communities. The Natural Communities of Georgia is an essential reference for ecologists and other scientists, as well as a rich resource for Georgians interested in the region’s natural heritage. Major support for this project was provided by the AGL Resources Foundation. Additional support was provided by the Georgia Department of Natural Resources, Wildlife Resources Division. In-kind support was provided by the Joseph W. Jones Ecological Research Center at Ichauway and Georgia State University.

1st Edition
by Lee E. Frelich (Author)
Lee Frelich provides a major contribution to the study of temperate-zone forest dynamics by considering three important themes: the combined influence of wind, fire, and herbivory on the successional trajectories and structural characteristics of forests; the interaction of deciduous and evergreen tree species to form mosiacs; and the significance of temporal and spatial scale with regard to the overall impact of disturbances. These themes are explored via case studies from the forests in the Lake States of Minnesota, Wisconsin and Michigan, where the presence of large primary forest remnants provides a unique opportunity to study the long-term dynamics of near-boreal, pine, and hardwood-hemlock forests.
