Eravikulam National Park (10°10' - 10°20' N and 77° - 77°10' E) is situated in Devikulam taluk Idukki District, Kerala and was established to protect the Nilgiri Tahr (Hemitragus hylocrius). It was stated as a sanctuary in 1975 and later in 1978, was declared a National Park considering its ecological, faunal, floral, geo-morphological and zoological significance. The present study was undertaken to assess the incidence of parasites among the Nilgiri Tahr which are exposed to the area used by humans beings.
