Abstract

The study of small carnivores of the montane forests of Eravikulam National Park in the southern Western Ghats, India recorded nine species of small carnivores using the camera trapping technique. These include three species of Mongoose (Herpestidae), two species each of lesser cats (Felidae) and civets (Viverridae), one species each of Otter and Marten (Mustelidae). They are Stripe-necked Mongoose Herpestes vitticollis, Brown Mongoose Herpestes fuscus, Indian Grey Mongoose Herpestes edwardsii, Jungle Cat Felis chaus, Leopard Cat Prionailurus bengalensis, Common Palm Civet Paradoxurus hermaphrodites, Small Indian Civet Viverricula indica, Asian Small-clawed Otter Aonyx cinereus, and Nilgiri Marten Martes gwatkinsii. It is interesting to note that the felines (lesser cats) are the more common small carnivores in the montane forests. Felis chaus was the most abundant small carnivore, which is followed by Prionailurus bengalensis and Herpestes vitticollis. Two species are Vulnerable as per the IUCN Red List, viz., Martes gwatkinsii and Aonyx cinereus.

Highlights

  • The montane landscape (>1500m) in the Western Ghats, a biodiversity hotspot, is situated in the hills of Nilgiris, Anamalais, Palni, High Wavies and Agasthyamalai Hills

  • Of the 16 small carnivores of Western Ghats, all except the Honey Badger Mellivora capensis, are known to occur in Kerala (Mudappa 2013; Nameer 2015); the small carnivore community shows a high degree of endemism in the Western Ghats

  • The Brown Palm Civet and the Nilgiri Marten are endemic to the Western Ghats at species level while the Stripe-necked Mongoose and the Brown Mongoose are endemic to the Western Ghats at the subspecies level (Pocock 1941; Menon 2014)

Summary

Introduction

The montane landscape (>1500m) in the Western Ghats, a biodiversity hotspot, is situated in the hills of Nilgiris, Anamalais, Palni, High Wavies and Agasthyamalai Hills. The natural vegetation in these montane landscapes is dominated by the grasslands, classified as 11A/C1-Southern Montane Wet Grasslands (Champion & Seth 1968). These grasslands are interspersed with isolated, compact and sharply defined stunted evergreen trees, locally known as sholas (Images 1 & 2) and classified as 11A/DS2 - southern wet temperate forests (Champion & Seth 1968).
