The state of Karnataka in South India has a rich diversity of flora and fauna. It has a recorded forest area of 38720 km2 which constitutes 20.19% of the total geographical area of the state.[1] These forests support 25% of the elephant population and 20% of the tiger population of India.[1] Many regions of Karnataka are still unexplored and new species of flora and fauna are still found. The Western Ghats mountains in the western region of Karnataka are a biodiversity hotspot. Two sub-clusters of the Western Ghats, Talacauvery and Kudremukh in Karnataka, are in a tentative list of sites that could be designated as World Heritage Sites by UNESCO.[2] The Bandipur and Nagarahole national parks which fall outside these subclusters were included in the Nilgiri biosphere reserve in 1986, a UNESCO designation.[3] Biligiriranga Hills in Karnataka is a place where Eastern Ghats meets Western Ghats. The state bird and state animal of Karnataka are Indian roller and the Indian elephant respectively. The state tree and state flower are sandalwood (Santalum album) and lotus respectively.[4] Karnataka is home to 406+ tigers (around 12% of tiger's in world).

Karnataka has five national parks.

Anshi National Park

This park is present in the Uttara Kannada district and spreads over an area of 250 km2. The altitude varies from 27 metres (89 ft) to 927 metres (3,041 ft), and temperatures from 15 °C to 35 °C. Average annual rainfall is about 4,700 millimetres (185 in) .

Bandipur National Park

It is situated within Chamarajanagar district covering an area of over 800 km2 and adjoins the states of Tamil Nadu and Kerala. In 1973, Bandipur became one of the first of India's tiger reserves and became a part of Project Tiger. In 1974, intention was declared under the Wildlife Protection Act to notify it as a national park.

Bannerughatta National Park

It is located in Bengaluru district and covers over 115 km2 of area. Altitude varies from 740 metres (2,428 ft) to 1,034 metres (3,392 ft), temperature from 20° to 35 °C and the average annual rainfall is 700 millimetres (28 in).

Kudremukh National Park

Spread over an area of 600.32 km2 it encompasses regions in the districts of Dakshina Kannada, Udupi and Chikmagalur. Altitude varies from 134 metres (440 ft) to 1,892 metres (6,207 ft). The park has a pleasant climate, with temperatures ranging from 17° to 28 °C. Annual rainfall varies from 1,778 millimetres (70 in) to 6,350 millimetres (250 in), with an average of 4,000 millimetres (157 in). The rivers Nethravati, Tunga and Bhadra are believed to originate here at Ganga Moola.

Nagarahole National Park

Also known as Rajiv Gandhi (Nagarahole) National Park gets its name from the Nagara Hole (Snake River in Kannada) which runs eastwards through its centre. Nagarahole river flows through the park before it joins the Kabini river that also acts as a boundary between Nagarahole and Bandipur. The park covers an area of about 575 km2. The Wayanad Wildlife Sanctuary of Kerala adjoins to the Southeast.

Dangers to flora and fauna

Due to various issues, flora and fauna in some parts of Karnataka are being threatened. These issues include poaching, human–wildlife conflict, habitat destruction, pollution and introduction of invasive new species.

Poaching

Despite the best efforts of conservation activists, poaching remains one of the serious problems affecting the flora and fauna in the state. Between the years 1997-2001, a total of 98 elephants have succumbed to poaching in Karnataka.[19] Poaching has also affected the breeding of turtles like olive ridley on the beaches of Karnataka as well as otters on the river banks. Tigers are also another species that are threatened to extinction by poachers.[20] Sandalwood, famed for its sculptures and its aroma is frequently poached out of the forests of Karnataka. Teakwood, famed for the furniture is another species of flora affected by this problem. Staff-shortage, lack of adequate funds and unscientific anti-poaching camps are some of the reasons quoted for continued poaching activities.[20] Travellers runs in these snake's forest they have to travel in glass covered buses so that traveler can escape from snake fall over these running buses, ďè

Habitat destruction

Some of the activities that are causing a destruction of habitat of flora and fauna in Karnataka are:

Human–wildlife conflict

Due to the loss of habitat, more and more species of fauna have started to venture into human habitation causing a conflict between humans and fauna. A typical species affected by this is the elephant which ventures out of the forest into human cultivations thereby eating or destroying the crops. In some cases, the elephants have also caused human deaths like an incident that happened in Hassan district where a villager was trampled to death.[22] Precautionary measures (sometimes illegally) taken up by humans to prevent such mishaps like electric fencing have also led to disastrous consequences like electrocution of fauna.[23]

Pollution

Release of industrial waste and human effluents into rivers have caused significant damages to species that reside in rivers and riverbanks. Air pollution is also a significant cause of concern in metros like Bangalore where it has been found that air pollution is discolouring foliage including those of ornamental plants.[24] A comparison of the lichen flora of the garden Lal Bagh in Bangalore has revealed that 18 of the 22 species noted in 1980 were no longer present in 1997.[19] Pollution in rivers like Kabini, Kaveri and Ghataprabha has caused sharp reduction in populations of bird species, including beneficial insectivorous birds like drongos, as well as honeybees.[19]

Invasive new species

Introduction of new species into a habitat has caused serious consequences to the existing species of flora and fauna. A typical example is the introduction of the African catfish (Clarias gariepinus) in the lakes and rivers of Karnataka. This is a carnivorous fish and has caused serious damage to the indigenous fauna living in those lakes and rivers.[19] Weeds like Eupatorium, Lantana and Parthenium have invaded large tracts of land causing destruction. An increase in Eupatorium is attributed as one of the causes for the spread of the deadly Kyasanur forest disease (which has a morbidity rate of 10%) among humans since it harbors tick populations that are vectors for this disease.[19] Eucalyptus plantations in the Ranibennur blackbuck sanctuary has seriously harmed the extremely rare great Indian bustard.[19]

Conservation efforts

Various conservation activities are in progress to protect the biodiversity present in Karnataka. These activities are mostly done by the Forest Department of the State of Karnataka and other voluntary organisations.

Relocation of human population

The presence of human habitation within the core area of reserved forests poses many problems like human–wildlife conflict and destruction of habitat due to agriculture and cattle grazing. Systematic efforts have been made to relocate some of this population into proper zones outside the protected area. An example is the relocation of some villagers from Bhagawathi and Nassehalla habitations within the Kudremukh National Park to safer regions outside it.[25]

Usage of technology

New scientific methods are being used to protect the flora and fauna. Some of these are:

Staff empowerment

It is highly important to keep up the morale of forest wardens and other staff members involved in anti-poaching activities and field trips. It is also necessary to keep them up-to-date on the technology and wildlife related laws. The following steps were implemented to address this issue:[27]

Recently discovered species

Many areas of Karnataka, especially in the forests of Malnad region are unexplored and new species of flora and fauna are discovered periodically. Some of the new species of flora discovered in Karnataka include Paracautleya bhatii (a ginger) and Isachne veldkampii (a grass), both of which were discovered near Manipal in Udupi district.[28] Two species of algae, Cosmarium bourrellyi and Cosmarium desikacharyi were discovered in a paddy field in Belgaum.[29] Other new species of flora discovered in Karnataka include Isoetes udupiensis[28] (a flowering plant) and Pisolithus indicus (a fungus).[30]

Some of the new species of fauna discovered include two species of ants, Dilobocondyla bangalorica which was discovered on the campus of Indian Institute of Science, Bangalore[31] and Discothyrea sringerensis which was discovered near Sringeri.[32] Three new species of frogs; Philautus luteolus, Philautus tuberohumerus[33] and Nyctibatrachus petraeus[34] have been discovered in Karnataka. Explorations in the Sharavathi river have yielded new fish species like Batasio sharavatiensis[35] (a bagrid catfish), Schistura nagodiensis[36] and Schistura sharavathiensis. Another fish species, Puntius coorgensis[37] has been discovered near Bhagamandala in the Kaveri river. Some other species of fauna discovered in Karnataka include two species of whiteflies, Distinctaleyrodes setosus[38] and Aleurocanthus arecae[39] and a caecilian, Gegeneophis madhavai.[40] Explorations in the soil around the Linganamakki reservoir has revealed eleven new species of earthworms.[41]
