Explanation:

Kalesar has 53% dense forest, 38% open forest, 9% scrub. Total forest cover is about 71%. Spread over an area of 11,570 acres (46.8 km2), Kalesar reserve forest is the only one of its kind in Haryana. Besides the tall, leafy sal trees that constitute the dense age-old forest belt of the Doon valley, there are other trees like Semul, Amaltas and Bahera.khair, shisham, sain, jhingan, chhal (Anogeissus latifolia) also found in the forest. It is the only forest in Haryana with a natural Sal tree belt. Among the flora is the small sindoor tree — it has dainty flowers, which turn into pods to produce the vermilion sindoor that adorns the tresses of married women. Climbers snake up the tree stems, and the forest floor is littered with fallen leaves and foliage plants. Sculptural anthills dot the landscape. There is a long stretch of man-made forest clearing and a 'fire line' which helps in containing forest fires.
