Site description (2004 baseline):
AVIFAUNA: Thanks to its remoteness, Grass Hills is perhaps one of the finest habitats in the Western Ghats for endemic and restricted range species. Although no detailed work on avifauna has been done, 8 of the 16 restricted range species have been identified. Along with Eravikulam National Park, this IBA is the main habitat of the Nilgiri Pipit Anthus nilghiriensis. Nilgiri Wood-Pigeon Columba elphinstonii and Broad-tailed Grass-Warbler or Grassbird Schoenicola platyura are other vulnerable and restricted range species found here. As a detailed checklist of birds of Grass Hills is not available, it is not known how many biome species are found here. The site lies in Biome-10 (Indian Peninsula Tropical Moist Forest.) Looking at the extent of intact shola, many biome-restricted species are likely to occur here, especially high altitude forest birds of the Western Ghats.
OTHER KEY FAUNA: Besides the Nilgiri Tahr, Grass Hills is famous for large herds of Gaur Bos frontalis. Other fauna include the Tiger Panthera tigris, Leopard P. pardus, Asian Elephant Elephas maximus, Sambar Cervus unicolor and Barking Deer or Indian Muntjak Muntiacus muntjak.
The site is well protected with no encroachment and there are no settlements, except a few in adjacent areas. Visitors have to seek permission from the Forest Department, and the site is not open to tourists. However, as the area is understaffed, poaching is rampant. Mishra and Johnsingh (1994) found at least three poachers with muzzle-loading guns during their survey. They also heard shots twice in one week. The Forest Department made several attempts to establish Wattle plantations. Pine (Pinus sp.) and Eucalyptus plantations can be seen near Konalar bungalow (Mishra and Johnsingh 1994). Wattle has already taken over the grassland near Konalar and along the fringes of Eravikulam National Park. It is now colonising the National Park area, seriously threatening the Tahr habitat. The Forest Department has uprooted and destroyed wattle from a few hectares so far, and the same has to be done in the remaining areas. The existing pine and the earliest Eucalyptus plantations are being used to meet the fuel wood and other requirements of the Konalar Bungalow. This is a desirable practice since it substitutes for fuel wood extraction from the sholas. Evidence of these species colonising more areas was not recorded, and the existing plantations should be maintained for fuelwood (Mishra and Johnsingh 1994). The streams have been stocked with Rainbow Trout Oncorhynchus mykiss which has affected local hill stream fish fauna.
