Earlier common throughout deciduous forests in India, four-horned antelopes are now found in low numbers. Their numbers were estimated at slightly above 10,000 in 2001, and are feared to be decreasing. In Mudumalai National Park, the populations are low and scattered. Their numbers in Gir National Park were estimated at 256 individuals in 1974; later estimates at waterholes in the same location put them a little above 1000. Densities of above 0.7 individuals per km2 have been considered as being healthy. Presently the four-horned antelope is confined to the Indian subcontinent, occurring widely in disjunct and small populations. The range in India covers a vast expanse, from the foothills of the Himalayas in the north to the Deccan Plateau in the south. Most of the existing populations are in India, and lower numbers in adjoining Nepal.
