Why in news?
- Last year, the Uttar Pradesh government received the approval of the Central Zoo Authority to set up a lion safari in 50 acres of forestland, just 5 km from Etawah town.
- Follow-up to that event, recently Modi vs Akhilesh verbal spat about lions vs hyenas during election campaign.
(Interview Q) From zoology/environment point of view, is it viable to move lions away from their natural habitat?
|yes because||no because|
Sequence of events:
- National Board of Wild Life took decision to translocate Gir lions.
- War of words between Gujarat and MP.
- Supreme Court PIL, court says yes shift Gir lions to MP. (2013) this is one example of “wildlife judicial activism”.
The action plan of Lion translocation:
- From Gir Sanctuary Gujarat to Kuno Sanctuary Madhya Pradesh.
- 25-year-long translocation programme.
- In next two years, 5-10 lions will be sent to MP. (60-70% of them will be females)
- Then every 3-5 years, a few more males would be sent.
- Sophisticated radio collars for all lions, constant surveillance by forest officials.
Interview: From zoology/environment point of view, is this viable to move lions away from their natural habitat in Gir?
- Government has notified Bor, Maharashtra- as the 47th tiger reserve of India.
- River: Bor, districts: Nagpur and Wardha districts; Mountains: Satpura-Maikal
- Bor sanctuary provides corridor between Tadoba-Andhari and Pench Tiger Reserves of the State.
- IUCN: Least Concern.
- Found across Asia- can survive in Himalayan highlands, Western Ghats rainforest and even Rajasthan’s desert.
- But, it is not a single species, Semnopithecus entellus (Hanuman Langur) consist of at least four distinct species.
|across north India|
|S. priam||drier parts of peninsular India|
|S. hypoleucos||mostly in the Western Ghats|
|S.Schistaceus||Himalayas but genetic profiling still undergoing.|
- Their feeding had migration behavior varies accoding to species.
- Therefore, we need to assess status of each population, to make customized conversation plans for each of them.
- IUCN: Near threatened.
- Spotted near Chennai coastline, and shallow waters, when sea is relatively calm.
- Occasionally, They also enter estuaries, lagoons and mangrove swamps in search of food..
- Population Declining because
- Gillnets and other harmful fishing gear
- Faecal coliforms in estuaries: hard for organisms to survive.
- IUCN Status: Critically endangered, Hardly 100 left.
- a rare species of fish in China- in Yangtze and Pearl Rivers.
- Lived since the age of dinosaurs.
- Nicknamed “aquatic pandas”.
- They swim all the way from rivers to the sea, to lay eggs.
- But this became difficult after construction of numerous dams, and increased boat traffic for inland navigation.
- Last year, no natural reproduction hence at the risk of extinction.
|WHAT||These green plants float on the water.|
|NATIVE TO||South America and Central America|
- IUCN status: DATA DEFICIENT.
- Where? only in the forest of Andaman and Nicobar
- it is the largest land crab [adult can be as long as 1 meter and weigh 4.5 kilos]
- Also called coconut crabs, because they climb trees, cut coconuts and descend to eat it.
|Avicennia variety||Ceriops decandra|
|also known as “Kalo Baine”||known as “Garan”|
|It has high tolerance to salt||It is less tolerant to salt.|
|This species is declining||This species has increased in Sunderban|
- This hints, water’s PH levels are changing and mangrove forest is adapting accordingly.
- This may also change the biodiversity and gene-variation in Sundarban.
