Site description Thaishola lies at the southwestern end of the Nilgiri Hills (Zarri et al. 2002). Taia Shola (= mother forest in Tamil) as the name suggests is a large, dense, undisturbed natural forest. A considerable area of the forest was reclaimed for tea plantation in the past, but now the remaining area is well protected. The forest, being undisturbed, harbours a host of resident and migratory bird species. There have been few botanical explorations in this area, while research on the bird community was almost nonexistent until the recent initiative by the BNHS. The major vegetation type at this site is Shola (Southern Montane Wet Temperate Forest) as classified by Champion and Seth (1968). Rhododendron nilagiricum, Rubus spp., Strobilanthes spp., Rhodomyrtes tomentosa, Solanum spp. are among the species commonly seen at the forest edges. These forests also harbour in their dense undergrowth a variety of ground as well as epiphytic orchids. The forest at this IBA is generally tall, up to 20 m. There is no grassland in the vicinity, but a few patches of plantation can be seen at the fringes. Thick shola stretches over the top of the hill, and is surrounded by the tea plantations of the Thaishola Tea Estate.
