Random amplified polymorphic DNA (RAPD) markers were used to evaluate the genetic diversity among populations of Jatropha curcas (L.) from different agro-climatic regions of India. Out of 305 amplified bands obtained with 30 primers, 291 were found polymorphic.
Bambusa tulda Roxb is distributed in Northeast India, Orissa, Bengal, Chhattisgarh, Bangladesh, Myanmar, Thailand and Indonesia. In Andhra Pradesh it has distribution in Visakhapatnam district.
Litterfall added by trees enriches the organic matter and nutrient content of soil under the trees. The influence of tree species was evaluated on soil organic carbon (OC), available macro (N, P and K) and micronutrient (Zn, Fe, Mn and Cu) concentration of soil and their accumulation in the soil.
Studies have been conducted to assess bamboo resources at both forest and non-forest areas in the state of Jharkhand. Information on land use, bamboo overlapping areas in forests, demographic features of the villages, households owning bamboos, species diversity, their growth, productivity etc have been collected on sample survey basis covering all the agro-climatic zones of the state.
Inspite of loss of many native flora from National Capital Territory (NCT) region, due to rapid urban growth, seven plant species that had not been hitherto known from this region, have been recorded.
The Shivalik range of Himalayas, represent the most fragile ecosystem in India, in order to restore the ecological environment in this area, a hilly watershed typical of the region of 21 ha area was brought under study in 1963. The watershed has been under complex protection and was treated by soil and water conservation measures during 1963-64.
A study has been undertaken to assess the number of six important tree species including teak, mango, babool, neem, kathal and shisham outside forests in rural areas of district Gorakhpur.
The impact of protection on the ecology and ecosystem services of a fragmented sacred grove of Karnataka in agricultural landscape was studied. Comparative assessment of two time scale data revealed positive influence of protection on vegetation in term of species richness, diversity, endemism and basal area. An increment in above ground biomass indicates groves potential for carbon sequestration. Species level study on carbon storage finds the contribution of young individuals in recent time period.
The field experiment was conducted during the year 2001 to 2006 on marginal degraded bouldery riverbed lands of Doon Valley in North-West India under rainfed conditions. The performance of grasses viz Panicum maximum (fodder grass) and Eulaliopsis binata (industrial grass for fiber and paper pulp) was evaluated alone and in association with Paulownia fortunei with regard to growth parameters and biomass yield.
Although the JFM concept is becoming popular more and more all over India, there is no well defined methodology to evaluate the functioning of JFM. As a result, it is not possible to evaluate JFM functioning and to find out the level of success of JFM. Therefore, an attempt has been made to bring out a concept paper on JFM that enables evaluation of JFM in a systematic manner.
