Spatial drivers of composition and connectivity across endangered tropical dry forests

1. Tropical dry forests are among the most threatened ecosystems in the world. Rapid loss, degradation, and fragmentation of these native ecosystems in a changing climate have driven a time-sensitive need to improve our understanding and management of remaining dry forests.

2. We used advanced remote sensing technologies, combined with extensive field data and machine learning, to better understand how spatial drivers (e.g., climate, fire, human) of canopy species composition vary in importance and correlate with forest cover (total, native and non-native), within an endangered Hawaiian tropical dry forest.

3. Past introductions of non-native, drought-tolerant tree species into this Hawaiian dry forest have created a new forest canopy composition and a loss of native forest biodiversity and connectivity at the landscape scale.

4. Synthesis and application. Our findings help to spatially visualize the loss and transition of native Hawaiian forests and provide a new conservation ...
