The coldest, driest desert on Earth.The Dry Valleys are dry because very little snow falls here, the average water content is less than a centimeter. Yet a fully functioning ecosystem exists here, in the ice-covered lakes and the soils of the valley floor. Even though the ecosystem is all but invisible to the naked eye, it still has a basic food web: primary producers (mats of moss and algae in the lakes, bacteria, yeast, fungi and other microbial life in the soils ), grazers (microscopic invertebrates called rotifers and tardigrades), with the top of the food chain consisting of tiny nematode worms (roundworms ).

This vegetation type can be seen above 1300m in Knuckles Range and can be seen areas such as Thangappuwa, Kalupahana and Gombaniya. During the year heavy mist can be seen in these types of forests. Montane forests are the most important catchments and water shed areas of the Knuckles Range.
It plays a key role in providing a water supply to sustain the ecosystems and livelihoods through the year in the downstream areas. These types of the forests contribute a lot when it comes to the natural beauty in Knuckles Mountain Range.
