This article relates to flora and fauna of the state of Kerala, south India. Most of Kerala, whose native habitat consists of wet evergreen rainforests at lower elevations and highland deciduous and semi-evergreen forests in the east, is subject to a humid tropical climate. However, significant variations in terrain and elevation have resulted in a land whose biodiversity registers as among the world’s most significant. But the district Alappuzha situated in Kerala is the only district of Kerala which have no forests. Evergreen forests Most of Kerala's significantly biodiverse tracts of wilderness lie in the evergreen forests of its easternmost districts; coastal Kerala (along with portions of the east) mostly lies under cultivation and is home to comparatively little wildlife. Despite this, Kerala contains 9,400 km2 of natural forests. Out of the approximately 7,500 km2 of non-plantation forest cover, there are wild regions of tropical wet evergreen and semi-evergreen forests (lower and middle elevations — 3,470 km2), tropical moist and dry deciduous forests (mid-elevations — 4,100 km2 and 100 km2, respectively), and montane subtropical and temperate (shola) forests (highest elevations — 100 km2). Such forests together cover 24% of Kerala's landmass. Kerala also hosts four of the world’s Ramsar Convention-listed wetlands: Ashtamudi Lake, Lake Sasthamkotta, Thrissur-Ponnani Kole Wetlands, and the Vembanad-Kol wetlands are noted as being wetlands of international importance. There are also numerous protected conservation areas, including 1455.4 km2 of the vast Nilgiri Biosphere Reserve and 1828 km2 of the Agasthyamala Biosphere Reserve. Parambikulam forest in Palakkad district is one of the jungle regions in Kerala. Flora of Kerala Eastern Kerala’s windward mountains shelter tropical moist forests and tropical dry forests which are generally characteristic of the wider Western Ghats: crowns of giant sonokeling (binomial nomenclature: Dalbergia latifolia — Indian rosewood), anjili (Artocarpus hirsuta), mullumurikku (Erythrina), Cassia, and other trees dominate the canopies of large tracts of virgin forest. Overall, Kerala's forests are home to more than 1,000 species of trees. Smaller flora include bamboo, wild black pepper (Piper nigrum), wild cardamom, the calamus rattan palm (Calamus rotang — a type of giant grass), and aromatic Vetiver grass (Vetiveria zizanioides). .......... The world's oldest teak plantation 'Conolly's Plot' is in Nilambur. Fauna of Kerala In turn, the forests play host to such major fauna as the Asian elephant (Elephas maximus), Bengal tiger (Panthera tigris tigris), leopard (Panthera pardus), nilgiri tahr (Nilgiritragus hylocrius), and grizzled giant squirrel (Ratufa macroura).
