The influx of elephant population in to the Coimbatore Forest Division occurs mainly during the post-monsoon and dry season periods. Elephant population from Bandipur Tiger Reserve, Mudumalai Wildlife Sanctuary, Nilgiri North and South Forest Division intensifies for a period of 3-4 months at a density of 1.5 elephants per sq km. However, this ecological density exists only for a short period. Although elephants migrate to this division only for spatio-temporal use including part of its annual home range, any threat to this reserve forest would affect the elephant population in the Nilgiri Biosphere Reserve.
Five corridors that are critical to contiguity of habitat within the division were identified. Two corridors, namely, Kallar-Jaccanare and Kallar-Gandhapallam were extensively studied by Sivaganesan, et al., (2000). The other three corridors, namely, Anaikatti-Anuvavi, Maruthamalai-Thanikandy, and Kalkothi-Walayar were also studied during this project period. Even though there was no wide variation among the tree species (32 to 34), very few species were found to be dominant in all corridors.
Thus, Albizzia amara, Bamboosa auridinaceae, Euphorbia antequorum, and Tectona grandis accounted for about 30% of the tree species in all three corridors. It is interesting to note that, elephant food species formed a high proportion of the tree species except Euphorbia antequorum.
The agricultural crops such as ragi, sorghum, sugarcane, and avarai were the most raided crops. Chilly, Grapes, and Marigold were the least raided crops by elephants in all corridors.
