Pristine Forest

Lying at western corner of the Kathmandu city, the Swoyambhu hillock (1403.76m) represents a surviving pristine forest in the metropolitan capital of Nepal. Once an extension of Jamaca (2096m) with luxuriant sub-tropical forest is now invaded by dense human population and other developmental activities. This hillock is still rich with a total plant species of 319. Of them, 65 are trees, 43 shrubs, 194 herbs and 17 climbers. Northern slope of the hillock is rich in tree species with scattered patches of under-growing bushes and ferns, whereas southern, western and eastern slopes are much disturbed with exotic species of plants, creating challenges to the norms of the heritage standard. Domination by Pinus roxburghii (chire pine) and Eucalyptus, Jacaranda and Callistemon, etc are altering the indigenous nature of the hillock. And also the forested hillock has been randomly utilized for refreshment, yoga, ayurbedic remedy and food. Due to growing constructions and exploitations, the forested hillock is now facing a threat to maintain its pristine ecosystem. <i>Nepal Journal of Science and Technology</i> Vol. 7, 2006

Functional And Phylogenetic Diversity

Abstract:Several studies have evaluated the short-term effects of tropical forest fragmentation on plant taxonomic diversity, while only a few have evaluated its effects on functional or phylogenetic diversity. To our knowledge no study has looked at the long-term consequences of tropical forest fragmentation on the three main components of plant diversity simultaneously: taxonomic, functional and phylogenetic diversity. We sampled the vascular flora using belt transects (50 × 4 m) in a continuous tropical semi-evergreen forest (16 transects) and in an adjacent naturally fragmented forest (fragments of 1.7-My-old semi-evergreen forest immersed in a mangrove/sedge matrix) (18 transects), and compared their taxonomic, functional and phylogenetic plant diversity. There were 36 species in the continuous forest and 28 in the fragmented forest. Continuous forest was taxonomically more diverse (25%) than the fragmented forest. All functional diversity metrics were greater (6–33%) in the continuous than in the fragmented forest. Phylogenetic diversity was 19% greater and phylogenetically more overdispersed in the continuous forest than in the fragmented forest. The results suggest that in the fragmented forest not only is taxonomic plant diversity lower, but functional and phylogenetic diversity are as well. The negative effects of forest fragmentation on plant diversity seem to be chronic.
