The diversity has been studied with respect to cumulative species richness and relative abundance, Shanon-Weiner diversity, bootstrap richness, Chao 1 richness, Coleman rarefaction richness. Attempts were also made to find a correlation with these parameters to the photoperiod of the day. Some of the potential threats of the wetland as well as the inhabitants have also been noted. In this current project the status and distribution of waterfowls in Santragacchi wetland were recorded and their description were described.

Species belonging to this family are usually known as grasses. Grasses are distributed in various climates, Soils and elevations on the surface of the glove. They have been recorded in marshes, deserts, prairies and woodland, on sand, rock and fertile, alpine and saline soils from tropics to the Polar Regions and from sea level to altitudes of perpetual snow. In the present study, We did taxonomic survey of grass species in Balaghat District of Central India. The grasslands of Central India got immense importance because these hold highest tiger population in the world and consequently a large number of deer species like spotted Deer and Sambar.

Both the leopards were fitted with VHF radiocollar, and 148 locations were collected from the first leopard (SP1) and 268 locations from the second (SP2). Third-order resource selection function (resource selection of the individual animal within its home range) was estimated from trans-located leopards using generalized linear mixed effect model with data on vegetation types, elevation, encounter rate of prey species and presence of tiger. With 100% minimum convex polygon (MCP), the estimated home range of SP1 and SP2 was 84.3 and 63.2 km 2 respectively. Both the leopards established their home ranges in and around the Sariska Tiger Reserve. The resource use of these trans-located leopards increased with increasing area of Zizyphus mixed forest and Acacia mixed forest, and decreased with increasing area of Anogeissus-dominated forest. Similarly, they selected habitats with higher encounter rate of wild pig and nilgai, and used less the habitats with high encounter rate of chital and common langur. Finally, it was observed that the 'problem' leopards in this study showed significant positive selectivity to the available natural vegetation types and wild-prey abundance, rather than degraded habitats and domestic prey species.

using scat analysis between November 2010 and June 2011 in Sariska Tiger Reserve, Western India. Total 104
scats of golden jackal and 86 scats of striped hyena were collected and analyzed. The frequency of occurrence
of each prey species was estimated through bootstrapping using program SIMSTAT. Niche breadth of these
two species was quantified using Levin’s measure. The diet overlap in the two species was assessed using
Pianka’s index. Twelve food items were identified in golden jackal scats and nine in striped hyena scats.
Vegetative matter contributed maximum (17.57%) in jackal’s diet followed by rodents (15.77%), chital (10.81%),
sambar (5.41%) and nilgai (4.05%). Nilgai and domestic cattle contributed maximum (24.76% each) in the diet
of striped hyena, followed by sambar (17.14%), chital (16.19%) and vegetative matter (10.48%). The estimated
dietary overlap between striped hyena and golden jackal was 67%. Niche breadth for golden jackal was
estimated as 0.69 and for striped hyena it was 0.57. The considerable overlap was attributed to mutual
dependence on ungulates, which indicated high resource competition between the two species.

Three tigers (one male and two females) were radio-collared and reintroduced in Sariska Tiger Reserve from Ranthambhore Tiger Reserve, Western India during 2008-2009. The reintroduced tigers were monitored periodically through ground tracking using "triangulation and homing in techniques." The estimated annual home ranges were 168.6 km 2 and 181.4 km 2 for tiger and tigress-1 respectively. The estimated summer home range of tigress-2 was 223.4 km 2 . In total, 115 kills and 103 scats of tigers were collected to study the food habits. The line transect method was used to estimate the prey availability. The density of peafowl (Pavo cristatus) was found to be highest (125.2 ± 15.3/ km 2 ) in Sariska followed by livestock (Bubalis bubalis and Bos indicus) (59.9 ± 22.3/ km 2 ), chital (Axis axis) (46.7 ± 9.5/ km 2 ), sambar (Rusa unicolor) (26.2 ± 4.9/ km 2 ), common langur (Semnopithecus entellus) (22.8 ± 6.5/ km 2 ), nilgai (Boselaphus tragocamelus) (19.5 ± 3.3/ km 2 ) and wild pig (Sus scrofa) (15.4 ± 4.4/ km 2 ). Tigers fed on seven prey species as shown by kill data. Tigers' scat analysis revealed the presence of five prey species. Prey selection by tigers based on scat analysis was in the following order: sambar> chital> nilgai> livestock> common langur. It is proposed to restock the tiger population initially with five tigers in Sariska and subsequent supplementation of two tigers every three years for a period of six years, which will allow the population to achieve demographic viability. Removal of anthropogenic pressure from the national park will be crucial for the long term survival of tigers in Sariska.

Twenty-five days of camera trapping was done with a sampling effort of 1,675 trap nights from January to April 2008. Camera traps yielded a total of 85 Hyena photographs of 26 individuals within an effective trapping area of 229.7 sq. km. Heterogeneous Jacknife model was best fit in estimating population with a capture probability of 0.31 P(hat). Population size was 34 ±(SE 5.4) and density was estimated as 15.1 ±6.2 hyena/100 sq. km (spatially explicit model). The study revealed that camera based capture-recapture method is an effective tool for assessing the population size of Striped Hyena in Sariska.
