Invasive Species

A Plague of Rats and Rubbervines takes a compelling look at this underappreciated problem and sets forth positive suggestions for what we as consumers, gardeners, travelers, nurserymen, fishermen, pet owners, business people - indeed all of us who by our very local choices drive global commerce - can do to help.

A basic fact sheet on arsenic compounds.

This publication includes information regarding reducing weeds during road maintenance.

A consortium has formed to develop, support and maintain an on-line, GIS-based, all-taxa invasive species mapping tool, iMapInvasives, focused on serving the needs of land managers, regional planners and others working to prevent, control or manage invasive species. A particular emphasis is placed on functionality designed to aid in Early Detection/Rapid Response (ED/RR) efforts.

Invasive species management programs help minimize the harm of invasive species on natural lands and encourage the health of native plants and wildlife.

This book includes chapters on the disturbance processes, how the disturbance causes necrosis or death to individuals, and their effects on population or community processes.

This illustrated handbook describes a variety of highly invasive plants impacting the region's natural areas. It provides identification tips, a few suggested native plant alternatives and some control information for a variety of invasive aquatic and terrestrial species in the mid-Atlantic region.

The manual presents a detailed overview of invasion biology and history as well as methods for establishing control efforts. Generalizations about invaders are derived from the literature and a suite of species that have affected several locations, most notably, South Africa, Australasia, Mauritius, and Hawaii. Species invasive in Europe, North America, and elsewhere are also included.

The book analyzes the factors that shape an invader s progress through four stages: arriving through one of many possible ports of entry, reaching a threshold of survival, thriving through proliferation and geographic spread, and ultimate impact on the organism s new environment. The book also reviews approaches to predicting whether a species will become an invader as well as the more complex challenge of predicting and measuring its impact on the environment, a process involving value judgments and risk assessment. This detailed analysis will be of interest to policymakers, plant scientists, agricultural producers, environmentalists, and public agencies concerned with invasive plant and plant pest species.

In this edited book, experts from the fields of ecology, evolution, and biogeography explore the unique insights species invasions provide. Several key advances emerge in each discipline, and collectively they provide a template for new research that transforms invasion biology into a powerful tool for basic research in ecology, evolution, and biogeography.

The Tennessee Exotic Plant Management Manual was written to provide natural resource managers and others concerned about exotics a tool to help control and manage 20 of Tennessee's worst exotic pest plant problems. The Tennessee Exotic Pest Plant Council (TN-EPPC), established in 1994, identified as one of its first goals the production of such a management manual for our region.

Charles S. Elton's classic The Ecology of Invasions by Animals and Plants was the first book, and still most cited, on invasion biology. It sounded an early warning about an environmental catastrophe that has become all too familiar today. Elton explains the devastating effects that invasive species can have on local ecosystems with numerous examples.

The manual includes keys to families, genera, and species; extensive diagnostic illustrations; scientific and common names; and data on distribution ranges, relative frequency, rare and endangered species, blooming and fruiting periods; with taxonomic notes and an illustrated glossary. The information meticulously reflects the plants as represented in Pennsylvania and is derived from specimens collected within the state.

This volume is the first published product of the Pennsylvania Flora Database, created & maintained at the Morris Arboretum of the Univ. of Pennsylvania. The database has its roots in the work of Edgar T. Wherry, John M. Fogg, Jr., & Herbert A. Wahl, the “Atlas of the Flora of Pennsylvania”, published by the Morris Arboretum. Over a period of 40 years, Wherry & his colleagues gathered data from the major Pennsylvania herbaria & manually placed a quarter of a million dots on over 3500 maps. The Pennsylvania Flora Database retains the emphasis on specimen-based, site-specific data. The checklist of included taxa has undergone extensive review to reflect recent taxonomic & nomenclatural revisions. Questionable specimens have been re-evaluated with the result that several taxa included in earlier works were dropped. Recent discoveries have been added & distribution data has been updated. This vol. also includes collections made in the 1990s in conjunction with the Pennsylvania Natural Diversity Inventory (PNDI), the state heritage program. The maps present the accumulated collection of information for each taxon as represented in the herbaria. Illus., reprinted 1996.

Todd, the recipient of the PEN/Jerard Award for this book while it was a work-in-progress, recounts how some of the approximately 4,500 exotic insects, mammals, and plants have been introduced to North America, occasionally for the better (such as with the Vedalia ladybug)—but more often wreaking destruction on native species.

Website with articles and resources for invasive species, including information on partnerships, grants, laws and regulations.

This handbook provides you with detailed information about the tools and techniques available for controlling invasive plants, or weeds, in natural areas. Whenever possible, language familiar to natural area managers is used, and unfamiliar terms and jargon borrowed from other fields are defined.

A lavishly illustrated manual for the identification of 299 common and economically important weeds in the region south to Virginia, north to Maine and southern Canada, and west to Wisconsin. Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower.

A partnership between the National Park Service and the Center for Invasive Species and Ecosystem Health at University of Georgia, this website has a profile of hundreds of invasive plants with pictures, maps of where they are found, and links to other websites with information about their control.

This manual summarizes the morphological characteristics, habitat requirements, life history, and possible methods of control for several common invasive plant species. Botanical terms used in the plant descriptions are not available on-line at this time. A reference section is included to acknowledge sources of information and to provide a reference to the literature addressing the problem of invasive species in Wisconsin. Sources for weed control tools, organizations, and other useful information are included in this section. Recommendations included here are limited to the control of some of the more problematic invasive plant species of Wisconsin. As control information on additional invasive species becomes available, and as users request information on other problem plants, these species may be added to the manual.
