Abstract

The damage to coconut and rubber plantations by the Indian crested porcupine (Hystrix indica) in the Nilambur Forest Division, Malappuram District was reported for the first time. The objectives of this study were to document the mode of attack and estimate the extent of damage by Indian crested porcupine in the plantation crops of the forest fringes. The study was carried out from June 2013 to May 2016 as part of the documentation of human-wildlife conflict in Malappuram District. Stratified random sampling, along with quadrat (10 m x 10 m) method was used to assess the crop damage. Estimation of the economic loss to farmers was carried out by using the market price of the coconuts during the period, collected from the website of Farm Information Bureau, Govt. of Kerala. The mean economic loss of crops damaged by Indian crested porcupine was Rs.1322.35/- per ha/annum. The debarking behavior of Indian crested porcupine on coconut palms (n=31), rubber trees (n=27) and consumption of newly formed bamboo culms (n=42) were also reported. No one has implemented proper mitigation measures against the Indian crested porcupine in the District.
