Monitoring of Land use/ land cover changes of Daying Ering Wildlife Sanctuary, Arunachal Pradesh, India, using Remote Sensing and Geographic Information System

The advent of geospatial technology plays a vital role in identifying environmental problems and provides solutions to good decision-making. In India, much of wildlife research and management occurs in protected areas. Therefore, it is imperative to study the landscape dynamics of such areas. The present study aimed to investigate the spatio-temporal of land use/land cover (LULC) changes that occurred in Daying Ering wildlife sanctuary, East Siang District, Arunachal Pradesh, for 10 years (2012-2022). The LULC were categorized into vegetation, water body, marsh, riverbed, and grassland. Supervised classification was used with the maximum likelihood algorithm in ERDAS 15.0 software. Post-assessment of the study area images revealed that there had been some major land changes whereby grassland has decreased by 25.10 %, an increase in the river bed (16.73%), and an increase in the water body (16.16%). The findings of the present study call for attention from researchers, environmentalists, policymakers, government officials and local villagers to study the consequences of LULC changes on vulnerable species and form mitigation/management measures accordingly

Do Trap-Neuter-Return (TNR) Practices Contribute to Human–Coyote Conflicts in Southern California?

One possible contributor to the unusually high number of conflicts between coyotes (Canis latrans) and people in urban southern California, USA, may be the abundance of free-roaming domestic cats (Felis catus; cats) subsidized by feeding and augmented by trap-neuter-return (TNR) programs. To determine if coyotes regularly prey on and consume cats, we combined visual and molecular-genetic approaches to identify prey items in stomachs of 311 coyotes from Los Angeles County and Orange County, provided to the South Coast Research and Extension Center, in Irvine, California, between June 2015 and December 2018. We detected cat remains in 35% of the stomachs of 245 coyotes with identifiable meals, making cats the most common mammalian prey item consumed and more common than reported previously. Using a geographic information systems approach, we then compared landscape characteristics associated with locations of coyotes that ate cats to public shelter records for TNR cat colonies. Cat-eating coyotes were associated with areas that were more intensively developed, had little natural or altered open space, and had higher building densities than coyotes that did not eat cats. Locations of TNR colonies had similar landscape characteristics. Coyotes associated with TNR colonies, and those that were euthanized (vs. road-killed), were also more likely to have consumed cats. The high frequency of cat remains in coyote diets and landscape characteristics associated with TNR colonies and cat-eating coyotes support the argument that high cat densities and associated supplemental feeding attracted coyotes. Effective mitigation of human–coyote conflicts may require prohibitions on outdoor feeding of free-roaming cats and wildlife and the elimination of TNR colonies
