Researchers
have found the existence of some rare species of birds, Slender Billed
Gull and Red Phalarope, and the Jungle Glory butterfly in the country's
forest reserves.
Of them, the Jungle Glory butterfly was spotted at Tanchi area of Bandarban hill district when researchers were updating the Red List of Species in Bangladesh for this year.
Prof Monwar Hossain of Jahangirnagar University's zoology department said this particular type of butterfly was last seen in the country some 132 years ago in forests in the Sylhet region.
The findings were unveiled at the 1st preliminary species assessment sharing workshop on updating species Red List of Bangladesh, held at the capital’s Spectra Convention Centre in the capital yesterday.
The Red List estimates the risk of extinction of a certain species which will help to set conservation plans and priority.
Two British military officials, Marshall GFL & Lionel de Niceville have documented the existence of Jungle glory butterfly in Bangladesh in their joint book named – Butterflies of India, Burma and Ceylon – published in 1882 by the British Museum.
“Later, many researcher had conducted several research on butterflies but never found the Jungle Glory in the country’s natural habitats,” added Monwar, who is also involved with updating the Red List.
Habitat loss by changing pattern of climate and forest ecosystem, and human intervention in forest has been considered as some of the primary reasons for the extinction of such species from the ecosystem, he added.
Meanwhile, the two birds’ species named Slender Billed Gull and Red Phalarope has been found in the country for the first time at the Padma River near Rajbari district in April and Slender Billed Gull has been seen at Teknaf area during last winter respectively.
Apart from this, the research team has also found a huge colony of particular type of bat, popularly known as the flying fox, at Altadighi area of Dinajpur district.
‘The flying fox colony consists of more than 1000, was found at a single compound at the area which was not seen before in the country,” said Prof Kamrul Hasan of zoology department of Jahangirnagar University.
Living together in a crowded space, the flying fox colony is unusual and indicates that these mammals like other bats has been suffering from an inadequate habitat and as a result of gradually depleting large trees and homestead forest in the country, he added.
The Updating Species Red List of Bangladesh Project was jointly taken by the IUCN and the Forest Department and will end by 2015.
In 2000, the IUCN published a Red List of Fauna Species in Bangladesh, covering the status of 895 species under five categories – mammals, birds, amphibians, fish and reptiles.
According to the list, different types of species including Gangetic ghorial, saltwater crocodile, hoolock gibbon, phayre’s leaf monkey, ritha fish, pungus fish and baghair fish were labelled as “critically endangered” due to the loss of their habitat and food scarcity.
The new Red List initiative has included two more categories – butterfly and crustacean (snails, crabs and shrimps), and the number of species will be increased to around 1,700.
