Generally three species of non-human primates occur in the State of Orissa (India). Among these only two species of non-human primates occur in the forests of Similipal hills of Mayurbhanj District. A census for different species of wild mammals occurring in the Similipal Tiger Reserve was undertaken during May, 2004. The results of population structure of two species of non-human primates, viz. Semnopithecus entellus entellus and Macaca mulatta were furnished. The census was carried out for four consecutive days in the line transect method covering a total distance of 122 km. Of the 144 troops sighted consisting of 1,505 Hanuman langurs, the mean troop size worked out to 9.6 ± 1.19. The highest and lowest density of Hanuman langur was 162.5 and 1.7 per km2 respectively. Similarly, out of 12 macaque troops sighted consisting of 138 individuals, the troops were made up of 4 to 25 individuals, with a mean of 11.5 ± 1.82. The population density was 10-98.3 per km2, with a mean of 26.86.Keywords

The Similipal Tiger Reserve (21°28' - 22°08' N latitude, 86°04' - 86°37' E longitude) of Mayurbhanj District, Orissa is one of the nine initially constituted Tiger Projects in India. The Reserve is a virgin sub-tropical forest and is a repository of large flora and fauna, which are a mixture of South Indian, North Indian and Andaman species. The Malabar or Indian Giant squirrel (Ratufa indica) which is distributed in Peninsular India, was also recorded in Similipal forest. According to the last census there were 10,660 squirrels estimated in Similipal Tiger Reserve. During the study period a total of 24 species of food plants have been recorded. Giant squirrel depends majority of time on seeds of some tree species. The study reveals that the squirrels were preferred more the petiole of leaf followed by fruit and bark of the tree as their food in all the months of the year. Data on nesting habits were recorded and a squirrel used more than 4 nests within a territory either to escape from nest predator or may provide shelter from natural calamities. The present communication deals with the study on the status of Giant squirrel (Ratufa indica) in Similipal Tiger Reserve, Orissa, India.- Economy of Resin Tapping from Pinus kesiya in Orissa, India

The paper presents a study on economy of resin tapping from Pinus kesiya in Orissa. The results indicate that performance ofthe species is satisfactory in both qualitative and quantitative respects. The proper period of resin collection is from February to October. Per quintal cost of resin collection comes to Rs. 900/- where as the sale price of one quintal of resin would be Rs. 2,100/-.- Provenance Trial of Pinus caribaea in Koraput, Orissa (India)

Result on seed germination, height growth, diameter growth and survival percentage are presented from a provenance trial (1983) at Koraput Research Station, Orissa with Pinus caribaea at the age of 10 years. A total number of 20 provenance i.e. 16 ofvar-hondurensis, 2 ofvar-bahamensis and 2 of var-caribaea are taken into account. Following an analysis of the above parameters, it is found that Prov-Santa Clara, Nicaragua of the var-hondurensis shows relatively better performance than rest of the provenances where as Prov-Cuba of the var-caribaea shows a poor result in comparison to other provenances.- A New Report of Hyblaea puera Cram.

Elephant census was carried out by the author twice in the Kuldiha Sanctuary of Orissa, one in June and the other in December, 1992. The result of such census has been discussed in this papcr. The Elephants in this sanctuary live in highly fragmented groups due to scarcity of food and biotic interference. Suggestions have been made to save this fragmented population from annihilation.- Human Impact on Tropical Deciduous Forests: A Case Study of Indian Sal (Shorea robusta) forests of Similipal Biosphere Reserve

With the aim of evaluating the impact of fuelwood collection for household and commercial use like sale in the urban centres and use in brick kilns on tropical deciduous forests, Similipal Biosphere Reserve in India was taken as a case study. There was a decrease of 418.07 ha dense forest (canopy cover more than 40 per cent) in compartments P3, P4 and P5 of the Reserve from 1997 to 2006 due to unsustainable removal of fuelwood by the local people. Everyday on an average 214 (s.d.19) bicycle-loads of fuelwood were transported to Baripada city from the above three compartments which was estimated to be 9538.39 m3 wood annually against annual increment of 4797.63 m3 only. The paper stresses on introduction of modern cooking fuels and stoves in and around the forest fringe villages, massive energy tree plantation, and alternative avocation to the people dependant on fuelwood sale.Keywords

The extent of genetic diversity within a species is an important determinant of successful adaptation to adverse environmental conditions. Assessment of extent of genetic diversity/variability is also important to monitor genetic erosion within a species. In threatened plant species, genetic diversity assessment helps in selection of genetically diverse populations to enrich the genetically impoverished populations, thus minimizing the probability of genetic drift. Confirming taxonomic identity of threatened species, particularly those belonging to species complexes with dispute identity, is another essential task in the conservation of threatened species, which is best resolved through molecular approaches. The present study estimated the genetic variability within and among the populations of four threatened species, viz. Justicia beddomei (C.B. Clarke) Bennet (Acanthaceae), Embelia ribes Burm. f. (Myrsinaceae), Madhuca insignis (Radlk.) H.J. Lam (Sapotaceae) and Cycas beddomei Dyer (Cycadaceae) using Inter Simple Sequence Repeat (ISSR) and Simple Sequence Repeat (SSR) markers for selecting the genetically diverse populations. The phylogeny was analysed through ITS (nrDNA) and matK (cpDNA) sequences to confirm the species identity.
The phylogenetic analyses confirmed four distinct species of Justicia, which also revealed that J. beddomei and J. adhatoda were sister groups with a common ancestor showing rapid parallel speciation with J. gendarussa in one clade and J. betonica in another. Madhuca insignis with extremely small population in the Western Ghats (Karnataka to Kerala) might have undergone either extensive hybridization or incipient speciation. In case of Embelia species, a greater evolutionary closeness between E. subcoraceae and E. floribunda was revealed, while E. ribes had a distinct clad. Both ISSR and SSR markers distinguished various genotypes of Cycas beddomei.

To prevent extinction of threatened species, in vitro regeneration protocols for the propagation of six threatened species were standardized. The regenerated micro-shoots were ischolar_mained in nutrient medium supplemented with low concentrations of auxin. The well-developed plantlets were successfully established in field conditions, thus improving the probability of self-sustenance of the introduced populations. The success story of these six threatened species reaffirms the role of in vitro propagation in conserving plants facing the threat of extinction.Keywords
