In several reserves, the entry of the city-based operator has allowed many more tourists to enjoy the wildlife experience, given the generally poor development of facilities by the forest development itself. However, there are diminishing returns from allowing unlimited mushrooming of resorts and hotels in the vicinity of national parks. The environmental impacts can be huge, especially in the absence of laws governing occupancy and land use. At the same time, entry of such private operators has edged out expansion of village-based eco-tourism facilities or even governmental ones. An illustrative example is the Corbett Tiger Reserve. The increasing number of tourist resorts coming up in the villages outside the boundary of the Reserve, on the banks of the Kosi river, is adversely affecting the natural forest corridor between Corbett and the reserved forests to its east. The movement of elephants and other mammals across this corridor is already being impacted and, in turn, will affect the viability of populations.
