[2][3] This forested area in the Shivalik foothills is covered primarily with sal with smattering of Semul, Amaltas and Bahera trees as well.

[5][6] However, it is alleged, absence of sufficient funds from the centre is proving to be a hindrance in wildlife conservation in the national park.

[7] The ancient Kalesar Mahadev temple takes its name from the a corrupted form of Kaleshwar, a moniker of Hindu deity lord Shiva.

[2] It is located near NH 907 on the east side and just 400 meter south of Kalesar Mahadev temple and 8.1 km north of Hathni Kund Barrage.

Surrounded with multi-layered gardens, and as typical of the Raj bungalow architecture, there are high-ceiling rooms, exquisite parquet flooring and teak panelling along walls.

It is bounded by Yamuna river to the east, Rajaji National Park in Uttrakhand to the northeast, Simbalbara National Park in main Shivalik Hill range to the north on Haryana's border with Himachal Pradesh, Morni Hills and agrarian farms to the west, and agrarian farms in planes of Yamunanagar district to the south.

Geologically speaking the Shivaliks belong to the tertiary deposits of the outer Himalayas and are chiefly composed of low sandstone and conglomerate hills, the solidified and upheaved detritus of the great range in their rear.

A dirt road diverts from the highway where a faded billboard announces entry into the reserve forest mainly consisting of Sal trees.

From top the effort is rewarded by a sweeping panorama of the 11000 acres (45 km2) of the great sal forest; criss-crossed by fire lines and meandering rivulets.

[3][10] Earlier May 2004 survey in collaboration with Wildlife Institute of India found wild boars, sambhars, hares, red junglefowl, porcupine, monkeys, chitals etc.

[11][12] It was set up by the Haryana Forests department in association with an NGO called Wildlife SOS, with the help of Government of India grant under the Project Elephant.

[11] Wild elephants also roam Kalesar and adjoining Rajaji National Park and Tiger Reserve spread across Uttrakhand and Himachal Pradesh.

As for the steps taken to ensure protection of wildlife and environment, the forest staff have been given weapons by the state government to tackle the menace posed by poachers.

The state had also set up two special environmental courts in Kurukshetra and Faridabad to deal with crimes related to poaching and illicit felling of trees from the area.
