Evaluating and Monitoring Invasive Plant Processes: Author: Repath, Charles Fitts; Date: 2005-05-15; Program: Land Resources and Environmental Sciences; Abstract: Non-indigenous plant species (NIS) are a concern for both natural area land managers and the public. These species are perceived negatively despite the fact that the processes and impacts related to NIS are not fully understood. Also, control is generally conducted without understanding NIS population ecology. As a result, few NIS populations have been successfully controlled. We studied the population ecology of NIS in natural areas. First, Linaria vulgaris was monitored at different spatial scales over three years to determine its invasiveness, and also to determine which life history states...; Download File | View full details

Invasiveness of Yellow Toadflax (Linaria Vulgaris) resulting from disturbance and environmental conditions: Author: Lehnhoff, Erik Adam; Date: 2008-05-15; Program: Ecology and Environmental Sciences; Abstract: Invasive plant species are considered to be one of the greatest threats to ecosystems and biological diversity throughout the world, and are thus often aggressively managed. The degree of plant invasiveness, however, varies both with environment and with type of landscape disturbance. This research was designed to understand how the factors of environment and disturbance affect the invasiveness of Linaria vulgaris (yellow toadflax) in southwest Montana and to quantify the varying degrees of invasiveness resulting from each factor. Data were obtained through four separate projects. The effects ...; Download File | View full details
