Monarch Butterfly Change Detection Assessment
Developed ArcGIS9 Models and Python scripts that synthesize multi-year IKONOS imagery classifications to detect areas of illegal deforestation within the Monarch Biosphere Reserve, Michoacan, Mexico.
Global Assessment of Mammal Biodiversity and Conservation Status
Developed Avenue and ArcGIS/Python scripts that interface mammal range polygon datasets with the MARXAN reserve design model to assess mammal conservation status under existing and hypothetical human impact scenarios.
Global Biodiversity/Carbon Richness Evaluation
Combined global datasets from different agencies using ArcGIS to examine correspondence among areas of
high biodiversity, areas of high carbon availability, and areas where conservation projects are generally
successful.
North American Ecoregion Assessment
Developed macros and other scripting tools in Avenue to query taxonomic databases of species
presence/absence in North American Ecoregions and compare results to other spatial databases to examine
diversity in relation to physical factors and human influences.
Species Range Mapping Tool for Madagascar
Created an ArcView extension and stand-alone VB application that predicts species ranges from point
observation databases and known limitations on species distributions.
Species Prediction Model for Butterflies in Central Nevada
Combined GPS field data with spatial datasets derived from USGS DEM and DLG data, climate data, and
satellite imagery to generate inputs for testing Bayesean modeling techniques to predict species butterfly
richness and occurrence in central Nevada mountains.
Spatial Analysis of Pollination in Central California
Classified a Landsat 7 TM satellite image into a land cover thematic map using ENVI image processing
software. Developed spatial models to relate this map in to field data to examine correlations between
pollination efficiency and distance to native and agricultural land covers.
Regional Prioritization/Reserve Design: Calakmul, Chiapas, Oaxaca, and Ecuador
Prepared data, provided real-time spatial analyses, and generated cartographic output for 3-day on-location
workshops to prioritize landscapes for biological conservation. Workshops were held for (1) the Calakmul
Biosphere Reserve, Campeche, Mexico; (2) Chimalapas Region, Chiapas/Oaxaca, Mexico (3) Parque
Nacional Podocarpus, Ecuador; (4) Sierra Norte de Oaxaca, Mexico; and (5) Sierra Costera de Oaxaca,
Mexico.
Biogeography of Moths in Costa Rica
Devised a spatially explicit model for comparing moth diversity to habitat fragmentation and ecosystem service delivery in and around Las Cruces Biological Station, Costa Rica.
General GIS Support for Jasper Ridge Biological Preserve/Stanford Planning Department
Provided project support, consulting, and limited instruction for GIS-related studies at the Jasper Ridge
Biological Preserve and the Stanford Planning Department. Assembled spatial databases, conducted various
spatial analyses, and provided cartographic output for researchers and university staff.
