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 < 45 o slopes > 95% of diet is composed of bamboo

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

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

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

12 Mantel Tests Inter-plot Floristic & RS Similarity Matrices Euclidean/Jaccard Matrices Tree Spp. Similarityp-value Spectral Similarity0.133< 0.05 NDVI Time Series Similarity 0.360< 0.001 VARI Time Series Similarity 0.382< 0.001

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.
