Book Description
There have been many well-publicized cases of invasive species of plants and animals, often introduced unintentionally but sometimes on purpose, causing widespread ecological havoc. Examples of such alien invasions include pernicious weeds such as Japanese knotweed, an introduced garden ornamental which can grow through concrete, the water hyacinth which has choked tropical waterways, and many introduced animals which have out-competed and displaced local fauna. This book addresses the broader context of invasive and exotic species, in terms of the perceived threats and environmental concerns which surround alien species and ecological invasions. As a result of unprecedented scales of environmental change, combined with rapid globalisation, the mixing of cultures and diversity, and fears over biosecurity and bioterrorism, the known impacts of particular invasions have been catastrophic. However, as several chapters show, reactions to some exotic species, and the justifications for interventions in certain situations, including biological control by introduced natural enemies, rest uncomfortably with social reactions to ethnic cleansing and persecution perpetrated across the globe. The role of democracy in deciding and determining environmental policy is another emerging issue. In an increasingly multicultural society this raises huge questions of ethics and choice. At the same time, in order to redress major ecological losses, the science of reintroduction of native species has also come to the fore, and is widely accepted by many in nature conservation. However, with questions of where and when, and with what species or even species analogues, reintroductions are acceptable, the topic is hotly debated. Again, it is shown that many decisions are based on values and perceptions rather than objective science. Including a wide range of case studies from around the world, his book raises critical issues to stimulate a much wider debate.
Olympic National Park

Book Description
Renowned for its old-growth rain forest, wilderness coast, and glaciated peaks, Olympic National Park is a living laboratory for ecological renewal, especially as the historic Elwha River basin regenerates in the wake of dam removal. In this classic guide to the park, Tim McNulty invites us into the natural and human history of these nearly million acres, from remote headwaters to roadside waterfalls, from shipwreck sites to Native American historical settlements and contemporary resource stewardship, along the way detailing the park’s unique plant and animal life. McNulty reminds us that though “the mountains and rivers remain ‘timeless,’ our understanding of the lifeforms that inhabit them—and the effects our actions have on their future—is an ongoing, ever deepening story.” Color photographs Practical advice on how to make the most of your visit Handy flora and fauna species checklists Inspiring descriptions of endangered species recovery Detailed look at Elwha River restoration after dam removal
Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington

Pages : 148
Book Description
This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors’ studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in ‘refugia’: locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).

Author: Life on the Rocks

Pages : 193
Book Description
The American mountain goat is one of the most elusive and least familiar species of hoofed mammals in North America. Confined to the remote and rugged mountains of the western United States and Canada, these extraordinary mountaineers are seldom seen or encountered, even by those who patiently study them. Life on the Rocks offers an intimate portrayal of this remarkable animal through the eyes and lens of field biologist and photographer Bruce L. Smith. More than 100 color photographs and accounts of Smith’s personal experiences living in Montana’s Selway-Bitterroot Wilderness Area accompany descriptions of the American mountain goat’s natural history. Smith explores their treacherous habitat, which spans the perilous cliffs and crags of the Rocky, Cascade, and Coast mountain ranges. The physical and behavioral adaptations of these alpine athletes enable them to survive a host of dangers, including six-month-ling winters, scarce food sources, thunderous avalanches, social strife, and predators like wolves, bears, lions, wolverines, and eagles. Smith also details the challenges these animals face as their territory is threatened by expanding motorized access, industrial activities, and a warming climate. Life on the Rocks showcases the elegance and charm of this little-known creature, thriving in some of North America’s harshest wilderness.
