Abstract

Medicinal plants have attracted considerable interest in recent years. Commcrcial enterprises and local dwellers are regularly exploiting natural heritage of these mcdicinal plants. There is an urgent need of conservation of these valuable medicinal plants through cultivation. Poor marketing structure in the country is the primary challenge towards its promotion and cultivation. In Uttaranchal, attention has been given to conservation/cultivation and its open trading system by the government. The present paper highlights the cultivation and opcn trading aspects of medicinal plants in the State.

Abstract

Temperate forest structure, species composition, dispersion, diversity and regeneration behaviour in relation to the physico-chemical properties of soil were studied in the Oakmixed coniferous forest in a part of Garhwal Himalaya during the year 2000. The study indicated that the total density and basal cover values in the tree layer varied from 630 to 1,590 stems/ ha and 20.04 to 82.51 m²/ha respectively. The maximum number of saplings and seedlings (520 and 720 stems/ha respectively) were observed on the highest altitude (2,100m asl), whereas, the minimum number of saplings and seedlings (200 and 100 stems/ha respectively), on the lowest altitude (1600m asl). The study further revels that the moist temperate forest is characterized by a patchy distribution of species and individuals with mixed species composition and the sites are represented by different dominants and codominant species. The values of diversity and concentration of dominance oscillated between 1.33 to 2.01 and 0.27 to 0.45, respectively. Physico- chemical properties of soils were found to be promising for the growth of forest. Availability of higher average organic carbon and nitrogen contents might have given birth to higher total basal cover values on 1,700m and 1,800m altitudes, whereas, lesser prevalence of these parameters on 1,900m and 2,000m altitudes apparent to lower total basal cover values.

Abstract

Biological transformation of carbon is a primary mechanism for removing carbon from the atmosphere. Standing stock of vegetation plays a major role in carbon sequestration at present as well as in the future. This biospheric carbon sequestration is essentially a huge natural biological scrubber for all emission sources of carbon. An estimated value of 2GtC is removed from the atmosphere each year by the earth's mantle of vegetation. Forest fires the world over due to ever increasing population pressure, release stored carbon into the atmosphere in large quantities every year. Forest fires not only damage the forest wealth but also release huge amount of the secured storage of carbon in the form of forests into the atmosphere. The present paper examines the carbon sequestration and consequences of forest fire carbon emission to the climate.

Abstract

The present study was conducted in the Keflarnath Forest Division, involving three high altitude villages to study the involvement of local inhabitants/villagers with the forest and their effect on forest composition and regeneration status. Investigation revealed that the average firewood and fodder requirement of the study area was 1093.35 kg/day/village and 4758.65 kg/day/village, respectively. Whole of this firewood is extracted from the adjacent forest. However, the fodder extracted from the forest was maximum 1211.14 kg/day at Sari village and minimum 838.24 kg/day at Makkumath village. The rate of exploitation of forest resources was verified by vegetation analysis where no regeneration has been recorded from all the adjacent forests of the selected villages. The total basal cover of all the species was highest (76.47 m²/ha) at Sari and lowest (46.94 m²/ha) at Krokhi village. The values are comparatively higher than the earlier reported values (5.61.59.39 m²/ha) for similar type of forest, again indicating the greater biotic pressure to the forest. Quercus leucotrichophora was found associated with Lyonia ovalifolia and Rhododendron arboreum in the study sites.

Abstract

The population structure and growing stock variations under various diameter classes were recorded in five distinct natural forests of Cedrus deodara of Garhwal Himalaya. In all, 25 sample plots (five on each site) of 0.1 ha were laid out randomly to observe the variations in the structure of growing stock under different sets of environmental conditions. The results have manifested that the highest total growing stock value (761.70±58.73 m³/ha) among all the diameter classes was recorded in Dewarkhal area (site No.3, at the highest altitude, 2300m amsl) in Uttarkashi District, where highest total basal cover (TBC) (60.5424±4.6362 m²/ha) and minimum density (313±23.44 trees/ha) of C. deodara individuals, along with highest potassium content (372.27±6.15 kg/ha) in the soil were present. On the other hand the lowest total growing stock value (298.54±99.65 m³/ha) was observed in Devidhar area (site No.4, at the lowest altitude, 1900m amsl) in Rudraprayag District, where the lowest TBC (34.2763±9.9157 m^l/ha) and the highest density (438:t43.08 trees/ha) of C. deodara with lowest values of moisture contents (17.57±1.20%) in the soil were recorded.

Abstract

In Sukhna Wildlife Sanctuary, Chandigarh the enumeration of vegetation was conducted during 2005 at five different sites, i.e. Lattwala, Bolianwala, Miyapur Ka Khet, Barotawala khet and Kansal. The results revealed that five sites yielded a total of 2720 stems and 25 species of trees ≥ 30 cm cbh with different combination of dominant and co-dominant species. Acacia catechu was dominant at Lattwala, Bolianwala and Kansal sites, Acacia nilotica ssp. indica at Miyapur Ka Ket and Dalbergia sissoo at the Barotwala site. The total tree basal area among the five sites ranged from 7.28 to 26.50 m² ha and total density varied from 280 to 1020 stems/ha. Carissa opaca and Murraya koenigii were the common shrub species in all the sites. The density of shrub layer among the sites varied from 3.0 to 2 13.05 stems/9m². Remarkable difference was observed in the composition of herbaceous flora including grasses. Both herb and grass species among the sites varied from 7 to 64 and 1- 26, respectively. The density value oscillated between 7.90 and 69.10 stems/m² for herbs and 0.22 and 146.93 2 tillers/m² for grasses. The diversity indices suggest that the Kansal site had greater diversity in all stratums except sapling layer.

Abstract

Seabuckthorn (Hippophae spp. L.) is an important plant of cold zones of Himalayas in India. In India, Seabuckthorn grows in high altitude, cold arid conditions of Ladakh (Leh and Kargil), Lahaul – Spiti, parts of Chamba (Pang) and upper Kinuar districts of Himachal Pradesh and Badrinath and Chamoli in Uttarakhand (Dwivedi et al., 2006). Seabuckthorn has also been reported from Sikkim (Basistha et al., 2001) and in Dibang valley in Arunachal Pradesh (Tiwari and Singh, 2001).
