Site details
Site description: Governor’s Shola is located in the northwestern corner of Tamil Nadu, on the interstate boundaries with Karnataka and Kerala. It lies c. 8 km from Ooty town along the Ooty-Porthimunth road. It is a part of the Wenlock Down’s Range in the Nilgiris South Forest Division. This site was known for its excellent natural forest and grassland till the first half of the 20th century. Today, much of what existed in the mid 20th century is converted into exotic plantations, as in many other sites in the Nilgiris. This site also experienced significant habitat loss over the years because of anthropogenic pressures from the surrounding villages and conversion of land to agricultural use. Nevertheless, this small forest area still harbours a number of bird species of conservation interest. Governor’s Shola is a medium size patch of shola amid a sea of plantations and cultivation. Species comprising such shola include Actinodaphne bourneae, Ilex denticulata, Litsea wightiana, Michelia nilagirica, Microtropis ramiflora, Pithecolobium subcoriaceum, Symplocos pendula and Syzygium arnottanum, Eurya nitida, Photina notoniana, Ternstroemia japonica, Berberis tinctoria, Heydotis stylosa, Leucas suffruticosa and Smithia blanda. Besides, several genera of Himalayan elements such as Rhododendron, Hypericum, Rubus, Lonicera, Gaultheria and Pittosporum are also common.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas) KBA identified in the CEPF Ecosystem Profile of the Western Ghats Hotspot (2007). Taxonomy, nomenclature and threat status follow the 2002 IUCN Red List.
Additional biodiversity: AVIFAUNA: Governor’s Shola holds a bird community with small populations of some of the globally threatened and restricted range species, besides many common birds also. A checklist of birds recorded in the area around this site is given in Zarri et al. (2002). Governor’s Shola is located in the Western Ghats Endemic Bird Areas (EBA), where Stattersfield et al. (1998) have listed 16 restricted range species. We could record only five such species from this site; most of them are associated with Wet Temperate sholas and Subtropical Broadleaf Hill Forest, which proves that some natural vegetation is still surviving. This site is selected as an IBA based on the presence of globally threatened and restricted range species, A1 and A2 criteria respectively, of BirdLife International (2001). OTHER KEY FAUNA: Most of the mammals found in the sholas of the Nilgiris are also found here. Noteworthy species are Nilgiri Langur Trachypithecus johni, Tiger Panthera tigris, Leopard P. pardus, Wild Dog Cuon alpinus, Sambar Cervus unicolor and Barking Deer Muntiacus muntjak.

Threats
Summary of threats to biodiversity at KBA: MAIN THREATS: Consequences of monoculture plantation and invasive species; Overgrazing; Conversion of forests into cultivation; Extensive use of inorganic pesticides. This shola has been subjected to a succession of large-scale monoculture plantations of Wattle Acacia mearnsii, Eucalyptus or Blue gum Eucalyptus globulus and Pine Pinus patula. Now, invasive weeds such as Scotch Broom Cytisus scoparius and Ulex europeus have invaded this site, putting further pressure on the natural ecosystem. Settlements around the site have grown mainly because of immigration of people from the plains encouraged by several development projects. This has resulted in habitat degradation through firewood collection, illegal tree felling and overgrazing. Depletion of the shola undergrowth has affected the population of important bird species such as the White-bellied Shortwing and the Nilgiri Laughingthrush. There is an urgent need to protect this area with the active involvement of the inhabitants of the surrounding settlements, if long term conservation of the biodiversity in general and bird community in particular, is to be ensured.
