  1. Forest Structure & Distribution Across the Giant Panda Geographic Range Jianguo (Jack) Liu (Michigan State University) Zhiyun Ouyang (Chinese Academy of Sciences) Jiaguo Qi (Michigan State University) Andrés Viña (Michigan State University)

  2. National Conservation Programs • National Forest Conservation Program (NFCP) • Grain-to-Green Program (GTGP) Liu et al., PNAS. 2008.

  3. Giant Panda Habitat • Forest cover (broadleaf, coniferous and mixed) • Altitudinal range between 1200-3800 m • < 45o slopes • > 95% of diet is composed of bamboo

  4. Giant Panda’s Geographic Range and 6 Mountain Regions Restricted to 3 Provinces Historical Range Current Range

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

  6. Field Data 540 field plots: • Forest cover/type • Elevation, slope, aspect • Stem density & basal area • Tree species composition • Presence of Giant Panda signs

  7. Forest Distribution Forest Cover ~ 30% of Giant Panda Range Coniferous ~ 48% Deciduous Broadleaf ~ 32% Mixed ~ 20% MODIS 2004-2007

  8. Altitudinal Distribution PCF – Planted Coniferous Forest NCF – Natural Coniferous Forest DF – Deciduous Forest PMF – Planted Mixed Forest MF – Mixed Forest

  9. Structure

  10. 210 tree species in 109 genera 22 Bamboo species in 6 genera Few species are widespread across the entire study area Species Diversity

  11. Species Diversity

  12. Mantel TestsInter-plot Floristic & RS Similarity Matrices

  13. Floristic and Phenologic Ordinations Floristic – Non-metric multidimensional scaling Phenologic – Polar Coordinate Transformation

  14. Floristic vs. Phenologic

  15. Nature Reserve Representation

  16. Conclusions • Forest constitutes a dominant land cover type • Altitudinal gradient explains the distribution of forest types • Significant structural differences occur among forest types

  17. Conclusions • A significant relation was found between floristic and phenologic similarities • Time series of VARI exhibited the highest relationship with floristic similarity • Time series of vegetation indices thus constitute suitable surrogates for evaluating floristic similarity across large geographic regions.
