Abstract

This study examines external and internal characteristics of porcupines burrow (Hystrix brachyura) and recorded the morphological of porcupine burrowing system in the area of Bintulu-Miri. All characteristics of burrow such as type of burrow respectively to the floor and roof of entrance hole in term of earthy, rocky or mixed, entrance exposure (North, South, East or West), hole dimension of height and width, soil texture, soil pH, slope angel and bearing or back bearing of entrance were determined and recorded. There are three different burrow construction observed in this study; earthy, mixed and rocky burrow. The roof construction of burrows are different from each other (rock, compact soil and fallen tree) while floor' construction is prevalently based on earthy element as they dig their burrow by themselves. The temperature surrounding entrance opening is range from 26°C-28°C while pH of the soil tend to be little acidic which range from 4.99-5.90. Porcupines preferred to excavate their burrow in clay loam area which gives high stability than sandy soil. Bun-ow' entrance hole preferred moderate steep slope (class B: 20-39°) descending the burrow tunnel with exposed to the East. This burrow architecture is assumed to provide them from predators and environmental changes.
