“…It remains unclear why the average weight of tiger prey was lower and the diversity of tiger diet higher during our study than during McDougal or Sunquist. It has been suggested that tigers include more species, as well as smaller species, in their diet when their primary prey (cervids) are unavailable (Sunquist et al 1999, Reddy et al 2004). However, owing to enhanced protection, cervid populations were most abundant during our study (Mishra 1982) suggesting that this was not the case.…”

“…Studies of tiger diet have been conducted throughout much of the range of the species, including India (Karanth & Sunquist 1995, Chundawat et al 1999, Biswas & Sankar 2002, Sankar & Johnsingh 2002, Bagchi et al 2003, Reddy et al 2004, Andheria et al 2007), Nepal (Seidensticker 1976a, McDougal 1977, Sunquist 1981, Johnsingh 1992, Seidensticker & McDougal 1993, Støen & Wegge 1996, Wegge et al 2009), Bangladesh (Khan 2004), Thailand (Rabinowitz 1989), Bhutan (Wang & MacDonald 2009) and Russia (Miquelle et al 1996). These studies indicate that tigers generally prey upon 8-15 species, and while they occasionally consume prey weighing up to 1,000 kg, the majority of tiger diet consists of small prey (i.e.…”

Fine‐scale spatio‐temporal variation in tiger Panthera tigris diet: effect of study duration and extent on estimates of tiger diet in Chitwan National Park, Nepal

Attempts to conserve declining tiger Panthera tigris populations and distributions have experienced limited success. The poaching of tiger prey is a key threat to tiger persistence; a clear understanding of tiger diet is a prerequisite to conserve dwindling populations. We used unpublished data on tiger diet in combination with two previously published studies to examine fine-scale spatio-temporal changes in tiger diet relative to prey abundance in Chitwan National Park, Nepal, and aggregated data from the three studies to examine the effect that study duration and the size of the study area have on estimates of tiger diet. Our results correspond with those of previous studies: in all three studies, tiger diet was dominated by members of Cervidae; small to medium-sized prey was important in one study. Tiger diet was unrelated to prey abundance, and the aggregation of studies indicates that increasing study duration and study area size both result in increased dietary diversity in terms of prey categories consumed, and increasing study duration changed which prey species contributed most to tiger diet. Based on our results, we suggest that managers focus their efforts on minimizing the poaching of all tiger prey, and that future studies of tiger diet be of long duration and large spatial extent to improve our understanding of spatio-temporal variation in estimates of tiger diet.

“…With this, the compensations paid for livestock losses by PTR management are also increasing (see the compensations records presented in (S3 Table). Tigers prey on large and intermediate bodied prey animals [24, 25, 26, 27, 28]. Thus, understanding how people and tigers interact in this landscape might provide conservation planners with important management insights for tiger conservation in livestock dominated landscapes.…”

Wild versus domestic prey in the diet of reintroduced tigers (Panthera tigris) in the livestock-dominated multiple-use forests of Panna Tiger Reserve, India

et al. 2017

Grazing livestock in openly accessible areas is a common practice in the multiple-use forests of India; however, its compatibility with the reintroduction of tigers to these areas requires examination. Here, we investigated the diet of tigers in a livestock-dominated multiple-use buffer zone of the Panna Tiger Reserve, India. We hypothesised that the presence of feral cattle, along with open-access grazing practices in multiple-use forests, would increase the incidence of predation on livestock by tigers, even when wild prey are available. We used generalised linear models to test whether predation of livestock versus wild animals was influenced by (1) the sex and age class of tigers, (2) season, and (3) the distance of prey from the core-zone boundary of the reserve. Overall, sub-adult tigers and male tigers killed more livestock than wild prey, even when wild prey was available. In the winter and rainy seasons livestock were killed in higher numbers in the buffer zone than in summers, this may be because of the seasonally changing livestock herding patterns in the area. Further, with increasing distance from the core-zone boundary, all tigers killed more livestock, possibly because livestock were more easily accessible than wild prey. Our results show that open-access and unregulated livestock grazing is not currently compatible with large carnivore conservation in the same landscape. Such practices will lead to an increase in negative tiger-human-livestock interactions. In conclusion, we suggest the need to encourage locals to corral valuable cattle, leaving feral/unwanted livestock for tigers. This simple strategy would benefit both local inhabitants and tiger conservation in the multiple-use forests of India.

“…Tiger, leopard, dhole, primates, gaur, wild boar and porcupine in one cluster could suggest the prey preference of the predators. Tiger scat analysis made by Reddy et al (2004), revealed that wild boar (Sus scrofa) was the most common prey followed by chital (Axis axis) and sambar (Rusa unicolor). In a detailed study Bargali et al (2004) reported that the plant matter was greater than animal matter in bear scats in all seasons and moreover, the presence of crop remains in the scat during the monsoon suggested their crop dependence, thereby increasing chances of human-bear conflict.…”

“…Use of indirect evidences in population density estimation and in determining prey-predator relations have been emphasized globally (Collins, 1981;Putman, 1984;Marques et al, 2001). Recently such indirect evidences from Indian forests have been used to study the population density, prey-predator relations and diet habits (Karanth and Sunquist, 1995;Jathanna et al, 2003;Kushwaha et al, 2004;Bargali et al, 2004 andReddy et al, 2004). The present work uses indirect evidences as an important field tool to ascertain the relative abundance of prey and predator and their activity in the selected shola forest areas under varied human interferences so that the conservation priorities could be ascertained for these isolated shola patches.…”

Indirect Evidences of Wildlife Activities in Shoals of Western Ghats, a Biodiversity HotspotsThe presence of wildlife fauna and its activities were ascertained with the density of the scat, dung and other markings or droppings of the wildlife abode therein. Attempt was made to find out spatial differences in the activities of the wildlife populations and to comment on the abundance of different preys and predators within shola forests of Western Ghat hill forests, a Biodiversity hotspot in India. An indirect sampling method, Transect Count Method, was employed to count dung/pellet group/scat and other markings in that area. Pachyderms were found to be mostly dominant in Varagaliar and Punnumala shola patches while scats of all the three important predators, viz., tiger (Panthera tigris tigris), Indian wild dog (Cuon alpinus) and leopard (Panthera pardus) were encountered only in Varagaliar shola. Greater abundance was recorded from Indira Gandhi Wildlife Sanctuary than Silent Valley National Park may be because of the restriction of animal movements in the former due to topographical barriers and its existence as isolated shola patches that led to a greater concentration of wild fauna in a relatively segregated forest cover.
