Flora and Fauna of Goa
Goa, being in the tropical zone and near the Arabian Sea, has a warm and humid climate for most of the year. The month of May is the hottest, seeing day temperatures of over 35 °C (95 °F) coupled with high humidity. The monsoon rains arrive by early June and provide a much needed respite from the heat. Most of Goa's annual rainfall is received through the monsoons which last till late September.
Goa has a short cool season between mid-December and February. These months are marked by cool nights of around 20 °C (68 °F) and warm days of around 29 °C (84 °F) with moderate amounts of humidity. Further inland, due to altitudinal gradation, the nights are a few degrees cooler.
Most of Goa's soil cover is made up of laterites which are rich in ferric aluminium oxides and reddish in colour. Further inland and along the river banks, the soil is mostly alluvial and loamy. The soil is rich in minerals and humus, thus conducive to plantation. Some of the oldest rocks in the Indian subcontinent are found in Goa between Molem and Anmod on Goa's border with Karnataka. The rocks are classified as Trondjemeitic Gneiss estimated to be 3,600 million years old, dated by the Rubidium isotope dating method. A specimen of the rock is exhibited in the Goa University.
Forest cover in Goa stands at 1,424 km², most of which is owned by the government. Government owned forest is estimated at 1224.38 km² whilst private is given as 200 km². Most of the forests in the state are located in the interior eastern regions of the state. The Western Ghats, which form most of eastern Goa, have been internationally recognised as one of the biodiversity hotspots of the world. In the February 1999 issue of National Geographic Magazine, Goa was compared with the Amazon and Congo basins for its rich tropical biodiversity.
Goa's state animal is the Gaur, the state bird is the Ruby Throated Yellow Bulbul, which is a variation of Black-crested Bulbul, and the state tree is the Asan.
The important forests products are bamboo canes, Maratha barks, chillar barks and the bhirand. Coconut trees are ubiquitous and are present in almost all areas of Goa barring the elevated regions. A large number of deciduous vegetation consisting of teak, sal, cashew and mango trees are present. Fruits include jackfruits, mangos, pineapples and blackberries.
Foxes, wild boars and migratory birds are found in the jungles of Goa. The avifauna includes kingfishers, mynas and parrots. Numerous types of fish are also caught off the coast of Goa and in its rivers. Crabs, lobsters, shrimps, jellyfish, oysters and catfish form some of the piscine catch. Goa also has a high snake population, which keeps the rodent population in control. Goa has many famous National Parks, including the renowned Salim Ali bird sanctuary. Other wildlife sanctuaries include the Bondla Wildlife Sanctuary, Molem Wildlife Sanctuary, Cotigao Wildlife Sanctuary, Madei Wildlife Sanctuary, Netravali Wildlife Sanctuary Mahaveer Wildlife Sanctuaryand the Salim Ali Bird Sanctuary located on the island of Chorao.
Goa has more than 33% of its geographic area under government forests (1224.38 km²) of which about 62% has been brought under Protected Areas (PA) of Wildlife Sanctuaries and National Park. Since there is a substantial area under private forests and a large tract under cashew, mango, coconut, etc. plantations, the total forest and tree cover constitutes 56.6% of the geographic area.
