2. Giant Panda’s Geographic Range Historical Range Current Range

3. Giant Panda Habitat • Altitudinal range between 1200-3800 m • <45o slopes • Require forest cover (deciduous & coniferous) • >95% of diet is composed of bamboo

4. Remote Sensing for Panda Habitat Assessment • Limited to provide information on forest cover (usually through non-hierarchical spectral classification algorithms) • Understory bamboo cover has been neglected due to the difficulty in isolating it from forest canopy

5. Objectives • Assess the spatial distribution of forests • Evaluate the structural characteristics of the forests at plot scales • Develop techniques for up-scaling from plots to nature reserves, mountain regions and to the entire panda geographic range

6. Field Data • 440 sampling plots: • Forest cover/type • Elevation, slope, aspect • Tree/bamboo stem density & basal area • Tree/bamboo species composition • 84 plots exhibited panda signs

9. What about information on bamboo distribution ? Hypothesis: Forests with bamboo have particular phenological signatures that can be used to map their distribution across broad geographic regions.

15. Conclusions • Forests are a very conspicuous land cover type (40-50%) • Areas that are habitat for the giant pandas represent ~25% of the forest areas • Some species associations can be isolated and mapped using their characteristic phenological signatures

16. Next Steps • Continue collecting field and remotely sensed data in all the mountain regions comprising the giant panda geographic range • Perform time series analyses in the entire geographic range to evaluate phenological traits (using high temporal resolution MODIS data) that can be related with different species associations • Evaluate relationships between local spatial heterogeneity and species richness using intermediate (e.g., Landsat) and high spatial resolution data (e.g., IKONOS)
