The tract covers an area of 1300 km2 and is a sub-watershed of the river Indus. The area (within the project area) is drained by two main nullahs; namely Musha’ga and Sherakot, which flow into the river Indus near Keyal and Pattan respectively.

The entire tract is a series of rugged mountains with elevations ranging from 600 to 5151 meter above mean sea level (AMSL). The topography of the area is rough with bare out-crops and desolate precipitous slopes breaking the continuity of the forests. Moderate slopes and flat pans are found near in the valley and are usually locations of habitations like Sherakot, Sheryal and Pichmuro.

Climatic Features
Palas in Summer
The tract experiences both dry sub tropical (below 5,000ft MASL) and temperate type of climate (5000ft+MASL). The area lies on the transitional belt between the Trans-Indus tract in the North-West and Moist Temperate valley of Kaghan in the South-East. Winter starts from early November with the first snow fall on higher peaks and lasts till March. During these months the temperature falls below zero degrees centigrade. A major portion of precipitation is received in the form of snow. Summers inside the valley are pleasant while heat and humidity below 3000 feet altitude is experienced. No meteorological observatory, so far, has been established in the area; however, data recorded at Besham and Naran observatories, having close resemblance with the climate of the Palas area, are available (see tables 4-6 below).

Kolai and Batera forests receive maximum of monsoon rainfall which decreases as winds travel towards 'North-east, due to mountain barriers. Back to Top
