Abstract : | BACKGROUND
We propose to develop and evaluate a GIS-based adaptive sampling design for early-detection of invasive species in National Parks by using rare plant species as a surrogate. Rare plants are an appropriate surrogate to address early detection of invasive species because in both instances the species are relatively difficult to find and population abundance is difficult to estimate precisely. Data on plant distributions in Shenandoah National Park, along with fully developed habitat models and GIS coverages, will provide a reliable basis for the simulation study (Young et al. 2003). Various adaptive and conventional sampling designs will be constructed that make use of predictions from habitat models and incidental reports. Performance of the designs in terms of ability to identify hot spots, estimator precision, and yield of rare individuals and species will be compared to a baseline design (e.g., conventional simple random sampling) to identify designs with the greatest efficiency and yield. After establishing through the simulation study that a GIS-based adaptive sampling design is effective for early-detection monitoring, we propose additional ‘out-year’ phases of work including field trials focusing on particular invasive species and implementation of a monitoring program. OBJECTIVES1) Develop a GIS-based adaptive sampling design that incorporates information on habitat value and incidental reports for early-detection monitoring of invasive species. 2) Evaluate the performance of GIS-based adaptive sampling designs relative to other adaptive and conventional sampling designs by using rare plant species as a surrogate. |
