My research investigates the causes and consequences of the fragmentation of natural habitat, and how we can best conserve and reconnect managed landscapes.
- Riparian forest degradation: Assessing forest characteristics using multi-temporal high-resolution imagery.
- Green Phoenix? Long-term assessment of landscape conservation policies in Costa Rica
- Landscape ecology of southeastern industrial forests: Quantifying the extent and regional impact of pine plantations using remote sensing and ecological data.
- The changing matrix: Assessing reforestation and functional connectivity in a Costa Rican habitat corridor.
