Nursery performance (height, diameter, survival, stem form, branching pattern and disease and pest resistance) was studied over several consecutive years and each year superior ...

Knowledge of the habitat and regulating factors is obligatory for protection and better management of these vultures. Therefore, different types of habitats were mapped using eight species distribution models. Presence records from field survey, published data and citizen science, and 23 bioenvironmental raster layers were the model inputs. Eighteen models were developed whose strength varied greatly. As per the performance indicators, GBM and GLM were found to be superior models for EGV. For EBV all models were acceptable. MARS, with good model strength, was rejected on the grounds of field verification. However, the Ensemble model, overall, was found the best. As per this model, good habitat was restricted mostly in the Tarai ecozone. The top two vital variables were NDVI, and bio13 for both the vultures. The most vital temperature variable for EGV was bio08 ...

Very little work has been done on biomass production and carbon storage in improved stock of Dendrocalamus strictus. Present paper is an attempt to fill the gap on the basis of study in dry deciduous forest region. Three replicates of twelve distinct superior clumps growing in an ex-situ conservation plot were studied. The plantation was raised by rhizome propagation method in dry deciduous forest region and maintained by adopting normal silvicultural operations for the species. Commercial suitability of different origin stock indicated that natural source was better for paper pulp and rayon while plantation origin was more suited to housing and furniture construction purposes. For biomass estimation harvest technique and green dry weight ratio method were adopted. Total biomass at three years age ranged between 182.7 - 207.4 t ha-1. Above ground and below gr...

Wetland information was collected from office records of the UP Forest department. Bird populations were estimated by transect method and block-in-flock-in-sector method for woodland and aquatic birds, respectively. Across the twelve selected wetlands a total of 486,182 individuals belonging to 161 species of birds on 15,592 ha were recorded during the winter of 2010-11. The data were analyzed to assess the relationship between wetland characteristics and avian populations. Aquatic vegetation, surrounding vegetation, water availability and climate were found as important factors related to avian populations. January was found to be the peak of bird assemblage, while winter times before and after January were the waxing and waning period, respectively. Species richness and species diversity of aquatic birds varied betw...

Litter fall was studied by litter trap method and litter decomposition by litter bag method. Litter input varied from 1.71 ha -1 yr -1 (one year old) to 6.4 t ha -1 y -1 (30 year old). Bulk of the litter was in the form of leaf litter (87.7 - 100 %) followed by wood (00 - 15.6 %) and reproductive parts' litter (00 - 3.3 %). Winter was the peak period while rainy season was the lean period of litter fall. Age, density and basal area did not show any definite relationship with litter production independently. Colour alteration in litter and variation in nutritional status were found very distinct. Decay rates indicated that approximately 54%teak litter decomposed in first sixmonths, starting from July. Nitrogen and phospho...

Propagation medium was ETP. D-75, S7C20, S7C8 066, S7C15, S7CI 2502 and 69/5 turned to be the best suited ones. Most of these are American clones. Overall performance of Italian, Australian, Dutch and German clones were inferior. Rotation age of above promising clones should be reduced to 6-8 years if grown for pulp and intercropping.

The study site is considered as an ideal wetland. This is located at 27 o 15’ N and 79 o 55’ E. Thirty four food plant species were identified to be eaten by 16 birds.These plants were the species of Alloteropsis, Arundo, Azolla, Ceratophyllum, Chloris, Commelina, Cyperus, Echinochloa, Eichhornia, Eleocharis, Hydrilla, Ipomoea, Jussiaea, Lemna, Najas, Nelumbo, Nymphea, Nymphoides, Oryza, Pistia, Polygonum, Potamogeton, Scirpus, Spirodela, Trapa, Typha, Vallisneria, and Wolffia. Common consumer birds eating plant parts were Coot, Pochards, Teal, Wigeon, Gadwall, Gargany, Goose, Whistling-duck, Mallard, Pintail, Shoveler, and Swamphen. These are primarily the migratory birds except Coot, Whistling-duck and Swamphen. Spot-billed Duck, and Indian Moorhen were occasionally seen ea...

After screening selected clones have been put on trial for field evaluation. Promising Populus deltoides clones among exotics are S7C4, S7C2, 113324, 3324, and 82-33-3 while indigenous one' are L-12, L-13, L-30, L-34 and L-52. These clones are to be now planted on large scale in monoclonal mosaic block design.
