Over the last few centuries, however, the soaring human and cattle populations have brought extreme pressures upon our natural resources. This trend keeping pace, with the rise in population started making a tangible impact upon the resources-potential during the last few centuries and since the turn of the century has been gaining momentum, so that it has now grown to menacing proportions.
Diversion of pasture and readily accessible forestlands to agriculture and to a host of other purposes and the consequent movement of cattle to the interior forests for grazing has not only wrested a large part of its habitat from wildlife, but has also caused a deterioration in the carrying capacity of the remaining habitat. Improved communications network in the forests, versatile vehicles, slackening of fire-arms further exposed the wildlife to serious hazards. Infirm statutory provisions aggravated the situation.
Faced with a shrinking habitat, competition from cattle, and poaching hazards, the prospects for wildlife are grim. The wild herbivore populations, which not very long ago were teeming and displayed wide variety in most parts of the country, have become greatly impoverished. Many species have become locally extinct, their habitat having shrunk to a small fraction and even there the number has gone precariously low.
Thus of the two sub-species of barasinga, that in the Sub-Himalayan tarai region stands grossly depleted while the once teeming Central Indian hardground sub-species is being helped to fight a last-ditch battle against extinction in the Kanha National Park of Madhya Pradesh fortunately an upward trend is now reported. The distribution of black buck, gaur and arna has now become local and scanty.
Of the mountain game, the markhor, the Himalayan and the Nilgiri thars have become scarce. Several species of birds such as the Great Indian Bustard, white-winged wood-duck and the pink-headed duck face extinction.
