In the rainy season, the frogs of 'Ghangar Ghang' are tied in one tone. Frogs are the nature of life, protection of the environment. The expansion of human habitation and urbanization clears the wetlands. Burglar's safe dwelling is missing. For this reason, the 'frogs' of the 'frogs' were heard relatively less in the street. Studies say 10 species of frogs in the country are endangered.
Experts say there are 49 species of frogs in the country. Although not extinct, these frogs are in vulnerable condition. Various species of frogs are endangered due to the loss of the wetlands due to the loss of the environment, the use of pesticides in agriculture, climate change, frog hunting for food etc. These amphibious animals play an important role in protecting the natural balance of land and on freight and water. Due to the overburdening of insects, the frogs are called 'the insect killers'. Working as a frog index, measuring the environment of an area.
According to the Red List or Red List of the International Union for Conservation of Nature (IUCN) 2015 International Organization for Nature Conservation, there are 49 species of frogs in Bangladesh. Of these, 10 species of frogs are in danger. Among the endangered frogs, two species are endangered, three species endangered and five species are inconclusive. 27 species are somewhat worrisome. Six species are not endangered
In addition, there are six species of informational deficiencies. It is not known exactly how it is in the state. Earlier in 2000, IUCN announced 22 species of frogs in the country. According to that time schedule, no species of frogs were in great condition. Three species of frogs were still in danger. And seven species of frogs were not in danger. As well as seven species of frogs were lacking in information.
Apart from this, in 2016 and 2016, the University of Zoology at Dhaka University studied the frogs in Dhaka, Rangpur and Dinajpur. These surveys show that 11 species of capital Dhaka and 13 species of frogs were found in Rangpur and Dinajpur.
Professor M. Niamul Nasser of the Department of Zoology at Dhaka University said in the light of the first light, there is not a good sign of frogs and the lack of information in the frogs. Day-to-day wetlands are getting reduced. People are filling the wetlands. As a result, the frog has reduced. On the other hand, due to the use of pesticides in the farming, the frogs are dying to a large extent. He said frogs are very important in protecting the balance of nature. Nuts are naturally suppressed by eating damaged pests of frogs. The frog is called the 'natural machine for insecticide'. A frog can eat half a million insects of his body every day. If they kept a lot of frogs in the crop, they could play a major role in controlling the insects.
Niyamul Naser said, due to frogs decreasing, other animals' food sources are also in crisis. Because frogs are aquatic animals, reptiles and birds' food. Due to the depletion of frogs at a high rate, the food of these creatures is also decreasing.
Another professor of zoology department of Dhaka University Mohammad Firoz Zaman said in the first light that there are 49 species of frogs in Bangladesh. Among them, green frogs, cola frogs, kuno frogs, frogs, and frogs are more likely to occur. There are a few small frogs out there, which are available only in forests. These frogs are mixed with the color of nature. They are hidden in the tree or blossom of color. Thus protect themselves from the hunters. He said, although all species of frog in the country are in very bad condition, even if not extinct.
Failure of environmental damage, water pollution and climate change - mainly due to these three reasons are frozen, Professor Firoz Zaman said. He said granulated insecticides were scattered in agriculture. It is very harmful for frogs. Due to this pesticide, the fungus starts from the small pona fish in the water.
Land use is increasing day by day. And the fallen wetlands, the ponds are decreasing. In this way, the balance of the environment is one of the reasons for the depleting frogs.
Another important factor is climate change. It is affecting frog breeding. The ideal time for the birth of jogh and ahshra month and the whole time of the frogs. For the survival of the frogs, there is a need for accumulated water. Now it is raining uneven. It is not about rain in almost like this time. But being As a result of this, frogs are encouraged in breeding, but the rain does not accumulate in the rain due to which the barks can not survive.
Professor Firoz Zaman commented on the importance of maintaining frogs to maintain the balance of the environment. He said, frogs eat harmful insects of crops. Large goldbags and green frogs are weighing 200 to 400 grams. These frogs can eat half a million insects of the body every day.
Working as a frog index measuring what the environment is like in an area. In some areas, frogs are considered more meaningful, there is a natural balance. In the absence of frogs, there is an environmental disaster.
However, there is not much research on frogs in the country, he said.
Forest conservationist Jahidul Kabir, Forest Conservator of Forest Department Zahidul Kabir acknowledged that there has been no effective research on frogs in Bangladesh. He also admits that the authorities do not have any attention in this regard. In the first light, he said that according to the Environmental Law of the country there are 40 protected areas. There was some survey in those areas. In the rest of the area, survey of the frog was not done and research done. Various species of frogs are endangered in the country. It was possible to identify the causes of frogs in the survey. But there are no information about the number of frogs in the country, he said.
