Abstract Variation in the foraging strategies of Sambar deer (Rusa unicolor) with changing plant availability has received little attention. The pellet group density and seasonal vegetation availability in tropical climatic conditions of dry deciduous forest of Pench Tiger Reserve, were assessed through indirect evidences (pellet group density). Stratified random sampling was used in different habitats from 2012 to 2015 on a seasonal basis. The Sambar deer (R. unicolor) is one of the largest deer species distributed throughout the Indian subcontinent. Pellet group data were collected on 10 m radius permanent plots at every 200 m intervals on line transects. Teak forest, teak mixed and bamboo forest was the preferred habitat during summer (89.87 ± 88.36), and winter (98.19 ± 94.59) seasons respectively. Microhistological study was conducted to understand the feeding preferences of Sambar through pellet groups. A total of 57 plant species were identified in summer diet. While 51 species of plants were identified in winter diet. Sambar is predominantly a browser and for the conservation of the declining population of Sambar, long undisturbed tract should be protected with preferred browse and grass species.
