Forest has a substantial prospective to mitigate the accumulation of green house gases by number of forestry options available. The policy makers adoption of broad goals for GHG reduction though has considerable potential to alleviate the buildup carbon. The Clean Development Mechanism (CDM) offers benefits through sink credits and reduces the negative impact of climate change. The paper elucidates the working of CDM, the manifold effect on carbon sink, harvestable wood products, flow of energy and nutrient as well as biodiversity conservation through mixed-species-plantation, the multistrata dynamics of carbon sequestration and management of afforestation and reforestation activities for mitigation.- An Encounter with Kalyanai (Short Statured Elephant) their Behaviour and Habitat: a New Race

Tiger crisis is a stark reality of our times. There is deep concern about but its implications are not fully and properly recognized. Conserving the tiger is to conserve the biodiversity and consequently nature itself, so very essential for our own existence. Development poses a great problem as it is diametrically opposed to conservation, in essence craze for tangible benefits vis-it-vis intangible benefits goes against objectives of conservation. Development of scheduled tribes living in and around forests, upto developed nation standards will further tax our limited resources to the detriment of Homo sapiens. The authors suggest levying a tax on hotel industry, earning from eco-tourism, to provide funds for the welfare of ecosystem people. Stringent measures should be taken to curb poaching, illicit trade in wildlife and its production, revamp the monitoring system by inducting scientifically trained person in the forest services etc. and bring back the lost glory.- Structure, Diversity and Regeneration Potential of Oak Dominant Conifer Mixed forest along an Altitudinal Gradient in Garhwal Himalaya

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.- Vegetation Analysis of Mangrove Forest of Krishna Wildlife Sanctuary , Andhra Pradesh , India

Paper reports on a detailed analysis of a mangrove forest of Krishna Wildlife Sanctuary , Andhra Pradesh. The study was conducted during July 2002 , and the vegetation was sampled through random sampling method. This type of study is done for the first time in Indian Context. The result shows that Avicennia officinalis , Rhizophora apiculata , Agiceras corniculatum , Bruguiera cylindrica , Ceriops decandra and Excoecaria agallocha are the common species with sufficient number of the individuals. Good regeneration of all these species were also recorded. Some areas viz. , Nachugunta beat and Machlipatnam , support sparse vegetation composed of helophyte species i.e. Suaeda nudiflora , S. monoicea , S. maritima , Salcorina brachiata , Helotropium curassavicum and grasses Aeluropus lagopoides , Sporobolus verginicus , Spinifex littoreus and Zoysia mortella. Few species of creeper Ipomoea pescarpae , herb Launea sarmentosa and hedges Cyperus arenarius and Fimbristylis polytrichoides have also been recorded. In newly formed silt deposits in inter-tidal regions , the grass Porteresia coarcata found growing as pioneer species. A pure stand of Prosopis juliflora spread over 6km area , where the seeds were brought by 1977 cyclone. In Sorlagondi beat well grown trees of Salvadora persica were also noticed.- Cicadas in Flame - Diminishing Background Music of the Forest

Santalum album is one of the most valuable species of Peninsular India. Due to heavy biotic pressure by the greedy one this species is struggling in its own land. Natural as well as artificial regeneration is having high mortality rate in its initial stage. This study intent the mortality rate of Sandal plants at different age groups up to 5 years with suitable host plant and the impact of the water conservation on its regeneration. The study was conducted during 1999-2000 in Toppur Plateau in Eastern Ghats, represented 10 hectare Sandal plantation under different host trees viz. Albizia amara, Tamarindus indica and Azadirachta indica. The results bave revealed that the maximum mortality 86.68% was recorded in 1-3 months age group, while minimum 7.70% in 3-4 years age group of plants. The mortality rate found gradually decreasing with the increasing age of plants and zero per cent mortality was observed in 4-5 years of seedlings. Thus care must be taken for Sandal seedlings up to the age of 4-5 years after transplanting. Total nitrogen, available phosphorus and potassium in the soil of study area ranged between 0.101 to 0.291%, 0.55 to 0.60% and 0.07 to 0.145%, respectively.- Vegetation Analysis of the Tirumala Hills, Andhra Pradesh

Paper reports on a detailed vegetational analysis of Tirumala Hills forest, Andhra Pradesh. The seven hills are of great tourist and religious importance as the holy shrine of Lord Venkateswara. More that 50,000 people flock to the shrine daily for darshan of the deity. Floristically these hills are very rich. Interesting to mention here the occurrence of seven endemic species viz., Cycas beddζmei, Shorea tumbuggaia, Boswellia ovalifoliolata, Pterocarpus santalinus, Terminalia pallida, Syzygium alternifolium and Pimpinella tirupatensis. Study was conducted in the year 2002, and the vegetation was sampled through random sampling method. The result presented in four groups. In Group 1: Hardwickia binata and Pterocarpus santalinus were main dominating species having density of 183 trees/ha and 133 trees/ha. The total trees, saplings and seedlings density of the whole stand was 667 trees/ha, 2167 saplings/ ha and 483 seedlings/ha, respectively. In Group II the structure of the tree component consisted 27 species of over 10 cm dbh. The trees, sapling and seedlings density of the whole stand was 551, 1274 and 980 individuals/ha respectively. In Group III The community consisted 40 species of which two, Ehretia laevis and Pterocarpus santalinus were dominant species. The total sapling and seedling density was 1087 and 847 individuals/ha. Group IV comprised mainly exotic speceis with 18 tree in which Anacardium occidentale, Grevillea robusta and Peltophorum ferrugineum were the dominant species.- Need to Revise the Definition of Silviculture
