Abstract

Habitat selection by Chinese pangolin (Manis pentadactyla) in winter was
studied in Dawuling Natural Reserve, Maoming City of Guangdong Province,
China, from December 1999 through February 2001. The objective of this
study was to determine the pangolins habitat requirement in winter
during poor environmental conditions. The dominant habitat of this
Reserve was classified into 4 types, i.e. mixed coniferous and broadleaf
forest (MCBF), evergreen broadleaf forest (EBF), coniferous forest (CF)
and shrub forest (SF). The results showed that the ranking of vegetation
types selected by pangolins in winter was MCBF > SF > EBF > CE.
Pangolins preferred MCBF, and avoided CF. The environmental factors
preferred by pangolins in winter were 30degrees-60degrees steep slopes,
middle of slopes and bottom of slopes, Sunny slopes, distance from human
disturbance source exceeding 1 000 in with a minor disturbance degree,
heavy (81 % - 100 %) undergrowth with good shelter conditions,
moderate (760 - 1500 m) elevation, and medium (31 % - 70 %) closure of
arbor canopy. The surroundings factors avoided by pangolins were sharp
slopes steeper than 60degrees or gentle slopes less than 30degrees,
shady slopes, distance from human disturbance source within 1000 m,
dense (71 % - 100 %) or sparse (0 % - 30 %) closure of arbor canopy,
medium or lower coverage (0 % - 50 %) of undergrowth, and the top of
the slope. Pangolins preferred south-facing burrow entrances with thick
cover, and avoided north-facing burrow entrances with bare or poor
shelter. The thick layer of shrub and herbs growing under the tree
canopy appeared to be especially important to pangolins during winter.
