Exotic Plant Invasions Across Landscape Patch Types On The Olympic Peninsula

This state-of-knowledge review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradication or control of nonnative invasive plants. The 16 chapters in this volume synthesize ecological and botanical principles regarding relationships between wildland fire and nonnative invasive plants, identify the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describe emerging fire-invasive issues in each bioregion and throughout the nation. This volume can help increase understanding of plant invasions and fire and can be used in fire management and ecosystem-based management planning. The volume's first part summarizes fundamental concepts regarding fire effects on invasions by nonnative plants, effects of plant invasions on fuels and fire regimes, and use of fire to control plant invasions. The second part identifies the nonnative invasive species of greatest concern and synthesizes information on the three topics covered in part one for nonnative invasives in seven major bioregions of the United States: Northeast, Southeast, Central, Interior West, Southwest Coastal, Northwest Coastal (including Alaska), and Hawaiian Islands. The third part analyzes knowledge gaps regarding fire and nonnative invasive plants, synthesizes information on management questions (nonfire fuel treatments, postfire rehabilitation, and postfire monitoring), summarizes key concepts described throughout the volume, and discusses urgent management issues and research questions.

The Olympic Peninsula. This remarkable and isolated corner of Washington State is a land where snowy peaks tumble down to a mist-shrouded coast and majestic rainfores lies only 34 miles from dry oak savanna. Within its borders grows a remarkably diverse flora, with nearly the same number of vascular plants as the British Islesan area 30 times larger. Rugged and remote, the Olympic Peninsula is a place where naturalists can still experience the thrill of discovering aspecies previously unknown to the area.This book is the first comprehensive inventory of the Peninsula's flora, bringing together the results of nearly a century of botanical explorations by the authors. With it's inclusion of recent changes in plant names, this text is also a crucial taxonomic reference. It is an essential tool for anyone involved in the study, restoration, preservation, or enjoyment of native plants and their habitats on the Olympic Peninsula.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Abstract: Abstract of thesis entitled EXOTIC PLANT INVASION OF UPLAND PLANT COMMUNITIES IN HONG KONG, CHINA Submitted by Leung Pui Chi For the degree of Master of Philosophy at The University of Hong Kong in October 2005 Plant communities in the continental tropics appear to have suffered less from exotic plant invasions than their oceanic island counterparts. Most attention has focused on near-pristine plant communities, while modern Hong Kong can provide a 'worst-case' test to examine the invasibility of a highly degraded tropical continental landscape. Exotic plant species in Hong Kong are most prominent in disturbed lowland habitats, while research on exotic plant species in upland plant communities is lacking. The major aim of this study was to investigate the general pattern and extent of exotic plant invasions in the plant communities of upland Hong Kong. Plant communities were surveyed in habitats exposed to different degrees of disturbance on Hong Kong's highest hill, Tai Mo Shan. Exotic plant species were most prominent along the roadside, with species richness but not percentage cover declining significantly with altitude. A small subset of the roadside exotics and a few additional species were found along a stream crossing the surveyed road. Invasion along streams was largely confined to exposed areas, while cattle disturbance might have facilitated invasion of shade-tolerant species in the shaded upstream areas. Most of the invaders were rare. A smaller subset of the roadside exotics was able to invade upland plant communities away from roads and streams, but only in unshaded areas recently disturbed by feral cattle. Seeds of exotic plants were found in cattle dung and two species germinated from dung in the study site, suggesting that feral cattle may act as dispersal agents. Eight of the nine hill streams surveyed in various parts of Hong Kong were invaded by exotic plant species. Invasions were largely confined to unshaded areas, but the bat-dispersed tropical Asian tree, Syzygium jambos, was found to invadeshaded streams without additional disturbance. Several commonly planted ornamental species invading the surveyed streams had roadside seed sources nearby. Surveys of both cattle-grazed and cattle-free open uplands away from roads and streams showed that exotic plant invasions were only found in the presence of feral cattle, and all were confined to unshaded and recently disturbed areas. No exotic plant species were found in closed vegetation or in open areas without cattle. The results suggest that the highly degraded tropical continental landscape of Hong Kong is resistant to invasions by exotic plants, which are still largely confined to chronically disturbed habitats. Feral cattle promote invasions where people are absent, but this problem still seems to be reversible. Only S. jambos appears to invade streams without human aid. Future control measures for invasive plants should focus on the control of feral cattle populations, eradication of existing invasions, and screening ornamental plants for potentially invasive species before planting in or near protected areas.
