“…Nearly everywhere in the world, studies on animal mobility and conservation are signi cant. These studies are extremely important, especially in the case of India given its enormous and expanding population (Kalsi, 2022;Sethi, 2022). People are moving toward the borders of forests as human population rises and resource availability per person declines.…”

Ecological connectivity in a landscape is one of the crucial factors for biodiversity conservation. Especially in case of large mammals like top carnivores. Frequent environmental changes have resulted in isolated world’s wildlife population which leads to increased pace biodiversity loss. Moreover, Increased human inhabitants and population shift towards the edge of forests provides animals with very less or no scope of living in the wilderness. As a result, ecological connectivity analysis and landscape planning are integral part of one another. This paper reviews the available techniques for quantifying dispersal in the landscape. A critical and thorough review of available theories of wide range of methods, techniques and tools for corridor analysis in conservation scenario is done in this paper. It also compiles various approach utilized globally. An exhaustive discussion on modeling techniques such as graph theoretic approaches (least cost path analysis, network analysis, etc), circuit theoretic approaches, agent based models and machine learning based approach is compiled for improved decision making.

“…India recorded the world’s largest number of elephant–train accidents [ 10 ]. Such accidents are the largest source of elephant mortality in India after deaths by electrocution [ 11 – 13 ]. Generally, elephants function as ecosystem engineers and seed dispersers and their substantial mortalities can cause cascading effects on ecological processes [ 14 ].…”

Railways are an indispensable component of sustainable transportation systems, but also exact a toll on wildlife. Wild Asian elephants are often killed by trains in Assam, India, where we assess temporal variations in the occurrences of elephant-train collisions (ETCs) and casualties during 1990–2018. This study also assesses spatially varying relationships between elephant-train collision (ETC) rates and elephant and train densities in the adjoining 10 km2 grid cells of 11 prioritized railroad segments using ordinary least squares (OLS) and geographically weighted regression (GWR) models. The temporal analysis indicated that ETCs spiked at certain hours and months. The adult and calf elephant casualties on the railroads were found to be two to fivefold high during the post monsoon season compared to other seasons. During the operation period of meter gauge railroads (1990–1997), the proportions of ETCs and casualties were only 15.6% and 8.7% respectively. However, these increased substantially to 84.4% and 91.3% respectively during the operation of broad gauge railroads (1998–2018). The OLS model indicated that both elephant and train densities explained 37% of the variance of ETC rate, while GWR model showed 83% of the variance of ETC rate. The local coefficient values of GWR indicated that both the predictor variables interplayed significantly and positively to determine ETC rates in the Mariani-Nakachari and Khatkhati-Dimapur railroad segments. However, the relationship between ETC rate and elephant density is significantly negative in the Habaipur-Diphu railroad, implying that the elephant population along this railroad stretch is significantly affected by railways through large scale ETCs. Hence, there is an urgent need to address long-term mitigation strategies so that elephants can be conserved by providing safe passages and survival resources along railway lines.
