Brown Treesnake Control: Economy Of Scales, Daniel S. Vice, Mikel E. Pitzler
Brown Treesnake Control: Economy Of Scales, Daniel S. Vice, Mikel E. Pitzler
Human Conflicts with Wildlife: 2002 Symposium
The accidental introduction of the brown treesnake (Boiga irregularis) to Guam led to the demise of most of the island’s native avifauna and herpetofauna. The snake is also responsible for significant economic losses through frequent power outages and consumption of poultry. Control of the snake, aimed at preventing its inadvertent dispersal from the island and protecting native wildlife and economic resources, is accomplished using specially designed snake traps, hand capture, snake detector dogs, and snake barriers. Although control tools capture large numbers of snakes, control efforts are labor intensive, costly, and ineffective in reducing snake populations across the …
The Economic Impact Of Invasive Species To Wildlife Services’ Cooperators, David L. Bergman, Monte D. Chandler, Adrienne Locklear
The Economic Impact Of Invasive Species To Wildlife Services’ Cooperators, David L. Bergman, Monte D. Chandler, Adrienne Locklear
Human Conflicts with Wildlife: 2002 Symposium
On February 3, 1999, the president of the United States signed an Executive Order 13112 on invasive species. Each federal agency was directed to detect and respond rapidly to control populations of invasive species, monitor invasive species populations, provide for restoration of native species and habitat conditions, conduct research on invasive species and develop technologies to prevent their introduction, and promote public education on invasive species and the means to address them. The United States Department of Agriculture’s Wildlife Services Program fulfills a federal responsibility for helping solve problems which occur when human activity and wildlife, including invasive species, are …

A wide variety of exotic tree pests can readily be transported into the United States on untreated wooden pallets, crating, bracing, and other solid wood packing materials (SWPM). Recent introductions of forest pests associated with importation of SWPM demonstrate that current United States import regulations are inadequate to exclude such pests. Nearly all (97 percent) of the quarantine-significant tree pests found by port inspectors are associated with SWPM. In spite of current bark-free import requirements, about 9 percent of maritime shipments contain bark, which provides habitat for numerous organisms. A pest risk assessment was conducted for the SWPM pathway to …
Standardizing The Evaluation Of Brown Tree Snake Trap Designs, Richard M. Engeman, Daniel S. Vice
Standardizing The Evaluation Of Brown Tree Snake Trap Designs, Richard M. Engeman, Daniel S. Vice
United States Department of Agriculture Wildlife Services: Staff Publications
The introduced brown tree snake has had devastating impacts on the native vertebrate fauna of Guam. Trapping is the primary means by which brown tree snakes are removed, either in support of reintroduction of endangered species or to deter their movement from Guam in cargo. Traps used to control brown tree snake populations have been continually evolving since the 1980s. Before general operational implementation of a new design, the efficacy of new trap developments must be demonstrated. In this paper we combine the current knowledge about brown tree snake control objectives and practicalities, the information gained from a variety of …
Survey Of Aquatic Plants In Corps Of Engineers Reservoirs, Kimberly D. Walker, Mark D. Sytsma
Survey Of Aquatic Plants In Corps Of Engineers Reservoirs, Kimberly D. Walker, Mark D. Sytsma
Center for Lakes and Reservoirs Publications and Presentations
A survey of aquatic plants in a selected Corps of Engineers reservoirs in Oregon was conducted. Cottage Grove, Dorena, Fern Ridge, Dexter and Willow Creek Reservoirs contained abundant aquatic plants. Potamogeton pectinatus and Potamogeton epihydrous were the most common native plant species. Myriophyllum aquaticum and Potamogeton crispus were the most widespread nonnative plants. Species richness in the reservoirs was correlated with trophic status and basin morphology. Shallow reservoirs that included extensive areas of nutrient-rich sediments that were historic flood plain soils supported the greatest biomass and number of species. Mesotrophic reservoirs had lower species diversity. Oligotrophic reservoirs with steep basin …
