Abstract: A survey was conducted between December 2000 and March 2001 on the population and density of Chinese pangolin (Manis pentadactyla aurita) in Dawuling Natural Reserve , Maoming , Guangdong Province , China. The results showed a population of 65.27 - 156.59 individuals with the average density of 1.85 - 4.43 ind./ km² in this Reserve. The average pangolin density ranged 2.46 - 5.90 ind./ km² in different habitats in the following order :mixed coniferous and broadleaf forest (9.00 - 15.08 ind./ km²) > evergreen broadleaf forest (3.48 - 7.36 ind. /^_km2) > shrub (1.78 - 5.46 ind. / km²) > coniferous forest (0.10 - 2.32 ind./ km² ) . The mean density of burrows in different habitats was 51.39 burrows/ km² with the identical order as the pangolin density : mixed coniferous and broadleaf forest (111.11 burrows/ km² ) > evergreen broadleaf forest (50.00 burrows/ km² ) > shrub (33.34 burrows/ km²) , coniferous forest (11.11 burrows/ km²) . The difference in pangolin burrow density among habitats was highly significant at P < 0.01. According to the density of pangolin population in Dawuling Natural Reserve, it was estimated that a population of 14 273.09 ±5 863.79 individuals in guangdong Province.
