View of grassland from Nong Pak Chi Observation Tower. The scoured earth area is a salt lick.Grassland: The grassland provides an important grazing habitat for herbivores like deer and gaur. The park rangers have done an annual burn every summer for more than 50 years to prevent the jungle from reclaiming the grassland and to promote re-growth of the grass. These are the easiest areas to view wildlife.
Salt Licks: The salt licks are scoured areas of earth containing high salt levels that the herbivores like to lick. Some of these are naturally occurring and were dug out by the elephants. Others were created by the park rangers who replenish the salt levels every year. They attract the herbivores and may also occasionally attract the carnivores that hunt them.
