Book excerpt: Excerpt from Role of Biological Control as a Management Tool in National Parks and Other Natural Areas Invasion by alien (exotic) species is among the most serious threats to protected natural areas. The potential of biocontrol to address this problem is often advanced by land management agencies such as the National Park Service (nps), but these agencies have had little direct experience with this approach relative to its application in agriculture. Whereas in agriculture specific weeds or insects are targeted in an already highly manipulated environ ment, the integrity of the entire system is of prima ry concern in natural environments. Most nps biocontrol work to date has been con ducted in cooperation with other agencies, primarily state and federal departments of agriculture, or has expanded on fundamental research by such agen cies. Natural areas also may benefit indirectly from the self-distribution of agricultural biocontrol agents into these areas. However, the National Park Service has itself in recent years initiated a basic biocontrol research program with the construction of a quarantine facility in Hawaii for containment of foreign insects, and has sponsored foreign explo ration for biocontrol agents. Biocontrol requires a large initial investment, specialized research facilities, and well-trained scientists. This procedure involves international travel, interagency and intergovernmental coopera tion, and communication to address conflicts of interest. This approach may not be applicable in every situation where control is desired because of conflicting management objectives or unavailability of suitable agents. However, successful programs have offered cost-effective long-range control with a minimum of apparent environmental disruption or requirement of active management, although indirect effects of introduced biocontrol agents in a native environment may be difficult to assess. Resource managers often look to biocontrol as the only feasible management approach for particularly well-established weed and insect problems over large areas. Individual alien species may be successfully con trolled in native systems; however, prospects for the overall restoration of intact, pristine systems in tropical and subtropical areas, and especially those in insular settings, are less promising. These areas are frequently under severe invasive pressure from numerous, recently arrived alien species which are available to recolonize cleared habitats. Native species, which evolved in the absence of disturbing influence on islands, are comparatively less able to compete with these influences.

Book Synopsis Science and Ecosystem Management in the National Parks by : William L. Halvorson
Download or read book Science and Ecosystem Management in the National Parks written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."
