A Framework for Spatial Risk Assessments: Potential Impacts of Nonindigenous Invasive Species on Native Species
Many populations of wild animals and plants are declining and face increasing threats from habitat fragmentation and loss as well as exposure to stressors ranging from toxicants to diseases to invasive nonindigenous species. We describe and demonstrate a spatially explicit ecological risk assessment that allows for the incorporation of a broad array of information that may influence the distrib...
متن کاملInferring invasive species abundance using removal data from management actions.
Evaluation of the progress of management programs for invasive species is crucial for demonstrating impacts to stakeholders and strategic planning of resource allocation. Estimates of abundance before and after management activities can serve as a useful metric of population management programs. However, many methods of estimating population size are too labor intensive and costly to implement,...
متن کاملMaking risk assessments more comparable and repeatable
Many of the objections to implementing Risk Management and acting upon risk results hinge on the subjectivity of the risk assessment system. This subjectivity makes it difficult to make risk assessments justifiable, repeatable, and comparable over an entire project, program, or organization. One cannot easily justify assigning a 30% likelihood to a risk occurring when others with more, the same...

متن کاملRisk assessment for invasive species.
Although estimates vary, there is a broad agreement that invasive species impose major costs on the U.S. economy, as well as posing risks to nonmarket environmental goods and services and to public health. The domestic effort to manage risks associated with invasive species is coordinated by the National Invasive Species Council (NISC), which is charged with developing a science-based process t...
