The dynamics of plant bioresources including agriculture is different in the hills from those in the plains. The agriculture and forestry are the two major land use types and play an important role in providing food and livelihood security.

There could be some reason for environmentalists to cheer. This year has seen a significant increase in snowfall in the upper region of Western Himalayas, the primary source of river water for northern India, vis-

Climate and its variability have been and continues to be the principal source of exceptional fluctuations which wreaked havoc on forests. In Chamba, up to an elevation of 1,800 m chir pine (Pinus roxburghii Sargent) is the main naturally occurring coniferous tree in forests.

Fundamental to the onset of the Indian Summer Monsoon is the land-sea thermal gradient from the Indian Ocean to the Himalayas-Tibetan Plateau (HTP). The timing of the onset is strongly controlled by the meridional tropospheric temperature gradient due to the rapid pre-monsoon heating of the HTP compared to the relatively cooler Indian Ocean.

The changing global scenario and the amendment of national legislations on ownership over biological resources and intellectual property rights over the indigenous knowledge evolved by the local communities for the useful exploitation of these resources, demands that agricultural biodiversity and indigenous knowledge rich countries like India identify the agricultural heritage sites and document t

The documentation of forest wealth in the Himalayas is of great importance because biotic pressure on them. The applied system of management and conservation of forests is of immediate concern for the present and future generation. Such study is useful to know the type of plant community development through succession under single stand management system.
