In this paper we attempted to present a glimpse of linkage between the nomads living in the pasture of Upper Mustang and their role in biodiversity conservation. The nomadic rangeland in Upper Mustang region harbors endangered Trans-Himalayan species like snow leopard, lynx, brown bear, Tibetan wild ass, Tibetan argali etc. with a variety of birds. It also harbors various medicinal species endemic to the region. Nomads are completely dependent on the livestock for the sustenance of their livelihood. There are only nine nomads families residing in rangelands of Upper Mustang, among them three families are resided in Lo- Manthang Panga area whereas four families in Dhalung/Chhujung area and one each in Lauchhe/Dhaknak area and Ghami Lekh area. Seasonal grazing is a customary practice for all nomadic families. Interview with the nomads (N=9) reveals that the grass availability in the pastures is in decreasing trend. They reveal increase in the number of snow leopard and blue sheep whereas the population of Tibetan Gazelle is in decreasing trend. Rijiphuwa and Pika are the two sites in Dhalung/Chhujung area where snow leopard and grey wolf are the main problem creators. In Lauchhe area (summer pasture) and Dhaknak area (summer pasture), grey wolf and snow leopard are the main problem animals. In comparison to other pasture, the families of Dhalung/Chhujung area faces higher number of livestock losses. Nomads use their own traditional measures to protect their livestock against predators. Large flocks of goats/sheep often come from Tibet to Dhalung/Chhujung area which increases the pressure during the summer and is also the root cause for the deterioration of the pasture. The daily activities of Tibetan nomads have created disturbances resulting adverse impacts on the biodiversity. During summer, the habitat of Tibetan gazelle and Tibetan wild ass is badly affected.

This paper deals in general with diversity of vascular plants, status of invasive alien species (IAS) and nationally threatened plant species, human use potentials of phytodiversity, and some phytodiversity-based measures to restore and improve the Ramsar characteristics of Beeshazar Lake and surrounding landscape system, which isa part of the Barandabhar forest corridor (BFC) - an extension of buffer zone of the Chitwan National Park, Nepal.

This paper emphasizes wildlife biodiversity and the management techniques and drawbacks particularly in Bhawal National Park. The park was declared a National Park in 1982; there was a great diversity of animal species at Bhawal National Park especially peafowl and jungle fowl dating back, to the British era as well as the Pakistani era. But unfortunately during and after 1971 there were neither reports nor any sighting of these attractive creatures. It is also remarkable; the remaining creatures such as civet, skunk, mongoose etc are endangered as well. The park management techniques and how they can be improved in order to preserve wildlife from the viewpoint of the Forest Department as the villagers couldn’t give any. Information through field observations, interviews and focus group discussions were collected. Conservation is the only alternative measure remaining for the rapidly dwindling small area of the Sal forest; The WMNCC will definitely have to come into effect if a consensus and status of the existing wildlife is to be published; The park management staff can also put up some colorful signboards depicting what species of wildlife that the tourist can find; Co-management of protected areas has great importance for conservation.
