We captured 14 tigers (nine from PAs; 5 outside PAs) across different age and sex classes. The tigers were monitored intensively between years 2014 to 2019 to study their movement and ranging patterns. A combination of Medetomine hydrochloride, Ketamine hydrochloride and Xylazine was used to immobilize animals in dosages based on the body weight, age, and sex. The drug mixture was remotely administered using an air-pressurized Dan-Inject projector (Model IM) and the animal was approached in a vehicle. The sedated animals were measured, weighed, radio-collared, and photographed. Furthermore, 3 leopards (two females and one male) were captured and monitored from 2014-15. Baited cages with drop-door mechanism were used to capture leopards. The animals were immobilized using a drug mixture of Ketmaine and Xylazine. We captured 5 dholes across age and sex classes including three adult males, one sub-adult male and one adult female. The dholes were intensively monitored from 2017-18 to study their ranging pattern. They were immobilized using tiletamine and zolazepam combination (Zoletil 100, Virbac) (Van Heerden, Burroughs, Dauth & Dreyer, 1991). The drug mixture was delivered from a vehicle remotely using Dan-Inject projector (Model JMSP.25) as no other method like foot traps, cages or lures proved suitable for dhole capture in a Tiger Reserve. Between 2017 and 2018, 4 wolves consisting of two males and two females were tracked intensively in the semi-arid landscape of Maharashtra. Wolves were captured using soft-catch leghold traps. 25 traps were set up in a circle and wolf gland lure No. 100 (Stanley Hawbaker and Sons, Fort London, Pennsylvania) was used as an attractant to trap wolves (Habib, 2007). Traps were monitored continuously and trapped wolves were captured using double threaded nylon hockey net (Habib & Kumar, 2007) and immobilized using a Ketamine–Xylazine drug mixture.
