The alpine meadows of the Uttaranchal Himalayas are well known for rich floral and faunal diversity. In order to study the alpine meadows of Uttaranchal Himalayas, the Valley of Flowers National Park (VOF; protected from livestock grazing) and the Khiron Valley (seasonally grazed by livestock) were selected. This paper reports plant community composition and species diversity in the VOF and Khiron Valley using stratified random quadrats of 0.25 m2. TWINSPAN was used for identifying the plant communities and Shannon Wiener Index (H') was used for species diversity. The central valley portion in the VOF that falls between 3,300-3,700m elevations obtained 9 plant communities whereas the Khiron Valley, located at similar elevation, obtained only 7 plant communities. In VOF, species diversity was higher (H'=2.93) than the Khiron Valley (H'=2.77). Plant species diversity decreased with elevation in both protected and unprotected alpine meadows. The results are discussed along with the management implications.

Phenology of alpine plants was studied in the sub-alpine and alpine zone of the Valley of Flowers National Park and Hemkund, located in the Western Himalayas. Transects were laid in both the areas and monitored for phenology at every 30 days interval. A total of 95 flowering plant species were found on the transects, of which 84% were forbs, 14% were evergreen shrubs and undershrubs, and remaining 2% were grasses and sedges. The vegetative phase peaked in June and from the same month flowering phase also increased in the valley. July and August were the best months for flowering. The prominent vegetative phase peaked earlier (in June) in the cushion forming forbs than in other forms. The growing season was longest at lower altitudes and decreased with increasing altitude from sub-alpine forest to alpine meadows.- Patterns in Distribution, Population Density and Uses of Medicinal Plants along the Altitudinal Gradient in Dhauladhar Mountain Range of Indian Himalayas

We studied the patterns in distribution, population density and uses of medicinal plant species in Dhauladhar mountain range of Himachal Pradesh in Indian Himalayas. The study area was stratified into three zones on the basis of forest types and altitudes. In each zone, quadrats were laid down for sampling of plant species, and the local people were interviewed for gathering information on medicinal uses of plants. A total of 184 plant species were encountered in the sampling plots, of which 86% had medicinal uses. Among woody plant species, the use of bark was highest, whereas in herbaceous species the use of leaf and ischolar_main was highest for treatment of over 32 groups of diseases. In terms of density, Pinus roxburghii was the most dominant tree species in subtropical forests, which declined in temperate regions and was absent in subalpine forests. Rhododendron arboreum was the most dominant tree species in temperate region whereas in subalpine forests it was replaced by Abies pindrow, in terms of density. Berberis asiatica and Vitex negundo were the most dominant shrubs in subtropical forests besides Lantana camera, whereas Berberis lycium dominated the temperate and Juniperus indica dominated the subalpine forests. The heavy infestation of Lantana camera in sub-tropical forests has degraded the habitats of native medicinal plant species. Spearman’s correlation indicates positive correlation between local uses and density of respective medicinal plant species (P < 0.05). The results are further discussed in light of medicinal plants conservation in this part of the Indian Himalayas.Keywords
