The Vidarbha Landscape (VL) is very important as it harbours a population of about 331 tigers and forms the connecting link between the central and southern Indian tiger populations. It plays a pivotal role in exchange of individuals and thereby facilitates gene flow between these two populations increasing the viability of tiger populations in India. There are 8 protected areas or wildlife divisions where these tigers live, but these refuges are scattered like islands in a sea of human dominated landscape. Therefore, knowing the locations of tiger movement corridors and probable areas of human tiger conflict is especially important for a wildlife manager.

Human-wildlife conflict (HWC) is the negative interaction between human or human property and wildlife and is a growing cause for concern among conservationists and scientists globally. Although HWC is a global phenomenon, there are certain differences in its manifestation as well as magnitude in developed versus developing nations. Developed regions of the world exhibit lower levels of direct dependence on forest ecosystems and their resources, as well as exclusionary management of the wildlife habitats. India, being a developing nation, is witness to an increasing intensity of human-carnivore conflict due to the fast-shrinking percentage of forest cover, that act as natural habitats of many carnivore species, due to a combination of factors including human population explosion, agricultural expansion, and large-scale developmental activities, leading to fragmentation and destruction of forest cover all across the country. The Central Indian Landscape (CIL) is one of the regions of high tiger populations and density in India with 6 Tiger Reserves featuring heavily as source populations, including Tadoba Andhari, Pench, Kanha, Satpura, and Melghat Tiger Reserves. But there is a disproportionate decline in forest cover as well as quality, which means that even though the populations of large carnivores are thriving, there isn’t enough pristine forest to support their growing numbers. This eventually leads to a spill-over of the carnivores into surrounding human-dominated landscapes (HDL). This acts as one of the major reasons for the burgeoning number of conflict cases between humans and large carnivores. The Vidarbha Landscape (VL) of the state of Maharashtra is facing a similar decline in forest cover leading to an increase in conflict cases. Records of conflict incidents were collected from the Greater Tadoba Landscape (GTL) which covers the divisions of Brahmapuri, Chandrapur & Central Chanda, along with the Tadoba Andhari Tiger Reserve (TATR), in the Chandrapur Circle. Using these records, hotspots of livestock depredation and attacks on humans were mapped using a hotspot analysis tool in ArcGIS. Various scientific and non-scientific methods continue to be tested to slow down the increasing rate of HWC across the world. One of the major hurdles in the implementation of a universal mitigation method to curb the number and impact of HWC is the heavy influence of local factors including topography, vegetation, and human demography of the region. This requires an intensive study of the patterns and causes of conflict in a given region. Studying conflict hotspots and understanding the emerging spatial and temporal patterns is a quintessential step in the process of mitigating the HWC of any landscape. An important step in that direction is the establishment of a comprehensive database, which can be used for trend analysis and predictions. The hot spot analysis of human-carnivore conflict for tigers, leopards, and sloth bears enables visualization of the spatial distribution of events of attacks on humans as well as livestock depredation by each species, hence aiding in the development of site-specific management strategies to mitigate the effects of human-carnivore conflict
