Five forest plantations, all located in the central Punjab, were sampled for knowing the abundance of burrows of the Indian crested porcupine (Hystrjx indica). It was estimated that an average block of 100 ha of the plantations 'harboured 5 porcupine burrows. The burrow entrances were generally located about 89 ± 24.41 cm above ground level. An average burrow had 4.4 ± 1.59 entrances in it, which measured 43.0 ± 8.32 cm high and 47.5 ± 21.45 cm wide. It was concluded that the plantation- cropland complex of central Punjab had a favourable effect on the population density of the porcupines in the region.
