Abstract

A number of floristic surveys were conducted in different localities of cold desert in Spiti valley of North-West Himalayas for documenting the medicinal and aromatic plant diversity. A total of 118 medicinal and aromatic plant species have been recorded, which were low in occurrence and sparsely distributed. They were also under threat mainly due to over exploitation, unscientific collection and overgrazing.

Abstract

Hill bamboos, locally called 'Nirgal', form a very important vegetation component in the Sutlej catchment falling under the Rampur Forest Division and Kotgarh Forest Division of Shimla District in Himachal Pradesh. Two species of this bamboo group viz. Sinarundinaria falcata and Thamnocalamus spathiflorus have been reported from these forest divisions. This paper, on the basis of empirical data, highlights the socio-economic significance of these bamboo species in the study area. Major threats to the wild populations of these species and conservation strategies for better management of this resource have also been discussed in this paper.

Abstract

Floristic studies were conducted in Renuka Wildlife Sanctuary from 1999 to 2003. A total of 395 species belonging to 316 genera and 115 families were collected and identified. It includes 228 species of medicinal and aromatic plants, 85 species of exotics. The biological spectrum of study area reveals that the vegetation is theronanophanerophytic. The life forms of the area are Megaphanerophyte (0.52%), Mesophanerophyte (12.34%), Microphanerophyte (16.54%), Nanophanerophyte (19.16%), Chamaephyte (7.61%), Hemicryptophtye (5.51%), Geophyte (2.10%), Hydrophyte or marsh plants (3.41%), Therophyte (31.24%), Liana (0.79%), Parasite (0.52%) and Epiphyte (0.26%). The higher percentage of therophyte when compared to normal biological spectrum is due to the climate being favourable for growth of annuals. It is also presumed that the dominance of therophytes and nanophanerophytes may have partly resulted from disturbance in vegetation and grazing.

Abstract

Montane bamboos are represented in the western-Himalayan State of Himachal Pradesh by two species i.e. Arundinaria falcata and Arundinaria spathiflora. Both these species, having great ecological and local socio-economic significance, have gregariously flowered across the State during the year 2000 and 2001 respectively. This paper documents specie-wise extent of flowering of these bamboo species in the Sutlej catchment of the State.

Abstract

Agroforestry plays an important role in the development and improvement of an area. The existing agroforestry practices in different parts of India and their potential contribution to sustainable development in cold desert region of Himachal Pradesh, India, as well as the potential for developing and improving agroforestry with rural people participation has been recommended. Different agroforestry systems have been suggested for improving tbe productivity of land in cold desert region.

Abstract

The study was conducted in the cold desert region of India in the State of Himachal Pradesh and Jammu & Kashmir. Colutea nepale1UJis Sims attains an average height of 1.20 m with 2.50 m² average crown area. The shrub provides effective soil cover and binds soil over an area of 3.25 m². The contribution of aboveground biomass was maximum (57.61%) to the total biomass followed by ischolar_main biomass (42.39%). The taper rate varies from 0.21 to 0.42 in tap-ischolar_main and 6.17 to O.30inlateral ischolar_main, which itself is an indication of the strong ischolar_main system of the species. Stem contributes maximum energy content (4400.0 cal/g dry weight) followed by ischolar_main (4000.0 cal/g dry weight) and leaves (3270.0 cal/g dry weight) in descending order.

Abstract

The article outlines the results of a study carried out for assessing the distribution and ecological status of Juniperus polycarpos C. Koch in cold deserts of Himachal Pradesh, comprising the districts of Lahaul and Spiti and Pooh Subdivision of Kinnaur district. A valley-wise inventory of the cold deserts under the species had been prepared and compared with the available records. Regeneration status and vegetative associates of the species in various valleys of the cold deserts have also been recorded. The results of study show that the species is under great threat due to the ever-increasing biotic pressure and poor natural regeneration. The article also suggested some measures to be initiated for its conservation.
