In our opinion, policies concentrating on habitat Priorities in the conservation of European conservation should be given priority over species-centred schemes although it must be remembered that it is sometimes lycaenids easier for policy makers to focus on the protection of a species rather than the more complicated process of habitat protection. Some conclusions can be drawn from all that has been discussed In general, we consider that our section on important habitats in the preceding sections.
Most butterfly conservationists agree for lycaenids is more relevant than the present paragraph on that some general considerations are to be kept in mind if any threatened lycaenids. Therefore, the In an attempt to make our list as impartial as possible we duty of ecologists and butterfly conservationists is to make have pooled data from five European-level compilations of these available in an understandable way to the people who threatened species Heath ; Kudrna ; Collins and make decisions.
Wells ; the Berne Convention Appendix II, and an The main considerations which emerge from our appraisal unpublished list drafted by Van der Made during the Wageningen are: Symposium on 'Status of Butterflies in Europe' in For 1 The fact that many lycaenid species are declining is every species appearing on a list we have given a score depending supported by evidence derived from most European countries.
Species appearing as indeterminate or other categories two most important factors responsible for species decline. As were not considered, and the Berne Convention species a consequence, such alterations should be stopped in the areas Appendix II have all been scored as 3. In this way the highest where endangered species have their habitat.
Accordingly, wetland lycaenids status in at least one of the lists referred to above. Species in the are unanimously regarded as the most endangered by butterfly 'rare' category are a more mixed group that can be interpreted specialists.
A European wetland register is urgently needed and as species on which different authors do not agree, or that are legislation passed in order to protect all European wetlands localised but common. As we have Such a list, however, is far from perfect, mainly because for already said, the most suitable international framework for such the north and centre of Europe there is a long tradition in an action is Ramsar which might be persuaded, at a future date, conservation studies, whereas in the south of the continent to incorporate butterfly data into the listing criteria.

They Anatolia and the Caucasus, but is certainly more than rare in should be maintained wherever they are vital for the survival of other parts of Europe e.

Polyommatus of the subgenus Agrodiaetus, for instance, have The policy of continuing with traditional practices may been recognised as separate species only recently. Accordingly sometimes need subsidies, but may be enough to keep high they were not included in older lists. Another case is Agriades standards of living in many areas as suggested by the IUCN zullichi which was considered a subspecies of the comparatively conservation policies, and by several conservation specialists common A.
Abandonment of former extensive the true endangered status of what is now considered a distinct agricultural areas should be monitored, because this may species. As a consequence, we think that Agriades zullichi, eventually lead to changes in habitat as a result of natural Polyommatus exuberans and P. Special care should be taken to satisfy the ecological requirements of protected species to ensure their survival. This will mean in many cases that management will have to oppose the natural succession of vegetation.

The level of grazing in the blue's grassland habitats was ant species.

Once it had enormous number of butterflies of diverse families with higher number in each of the families and the butterfly population was in jubilant condition by having enough host plants, nectar plants and shelter plants are in the wild state.
Nevertheless, the EBBL laboratory estimated more than three hundred butterfly species still existed in this forest. In the EBBL research- study about the forest since , it is revealed that the butterfly population depletion is rapid, serious and alarming to be extinct very soon Bashar, The park is located at Kamalgonj Upazila, Maulvi Bazar district in the northeastern region of the country Lawachara. It is remarkable to note that, the largest butterfly of Bangladesh the Birdwings are found in this forest.
A decade ago this forest was with abundance of the Birdwing butterflies, but in the present situation their population has declined to the critical condition. This trend has been started in the forest owing to the fact that the host-plant is under a serious threat of the indiscriminant interference of human activities.
The Birdwing population has been declining alarm since As per the record of the EBBL, the highest number of butterfly species more than species was represented up to in the forest Bashar, Still butterfly population in the forest is rich more than in comparison to the population in the other forests of Bangladesh.
Largest butterflies the Birdwings are found in the forest with host-plant bushes. Butterfly populations are still high in the forest but very soon the population decline will be very colossal as the rate of forest destruction has already been started Bashar, But out of all forests under the experimentation of the EBBL, the butterfly population in this forest is less disturbed by the humans.
Butterfly estimation is poorly studied in the forest still today. So far the estimation is made by the researchers of the EBBL, the population volume may stand with more than species of butterflies Bashar, Anarashbari forest area This station is in Habiganj. Generally, It is a cultivated area.
Butterfly population is not rich in the forest, but still there are some species that are confined to the butterfly host plants which are poorly distributed and surviving. The EBBL report states that not more than 90 species of butterflies are estimated in the forest Bashar, Butterfly Conservation and Research Center a.
Total area is acres. It is proposed for a butterfly museum and an insect sanctuary along with the farm and the research center Mondal, Initially a 2 acres of land is going to be worked on, and there will be provisions for more expansions of the butterfly farm in the future Mondal, Total area is 10 acres. Mainly it is a natural park where not only butterfly but also many animals come for its natural setting There are types of trees are in the park and they are related to butterfly escalation.
There are three categories 32 beds provided for butterfly Mondal, Specimen and stuffing of about species are kept here. The authority has built a herbarium of about types of trees. The tourists, the students, and the researchers can obtain huge knowledge from this museum. Mainly the park is created for wildlife animals but Butterfly Park is one of the attractive parts of this park.
The gravity Level is so low down for butterfly flying capacity. Here humidity level is not sufficient for butterfly survival. It is not Eco-friendly. The basic plant for butterfly is not sufficient here and most of the plant dies. Plantation process is not done properly Mondal, Here temporary shell is made for butterfly.
Mainly Caterpillars are kept in the shell and are watched them grow up. But most of the butterfly used to die because of Humidity control level. Some photography exhibitions are held in the gallery. Mainly it is for the awareness of the people.
With proper conservation measures, we can help them to better cope with ongoing climate change. Wildflower plantings-plantation of wildflower gardens that contain an assortment of native trees, shrubs, and grasses are one of the easiest means of attracting butterflies to an area.
Because adult butterflies rely heavily on nectar as their primary food source. Garden design-wildflower gardens that include taller trees and shrubs behind shorter species can be aesthetically pleasing. Create puddles-providing a source of water in the form of shallow, lined depressions or puddles, small fish ponds, birdbaths or simply a sand-filled bowl buried in the ground will collect water to help attract butterflies to wildflower plantation NRCS and WHC, Besides other initiatives can be taken as follows: Encouraging native legumes dock, milkweed, nettle, and native grasses; Reducing pesticide and herbicide use in agricultural areas when possible NRCS and WHC, Using mechanical means of pest control to minimize loss of nectar-producing trees, shrubs and flowers; Maintaining natural and planted grassland by conducting prescribed rotational burning; Restoring hydrology and vegetation in forested wetlands; Preserving existing trees, shrubs, vines, hedgerows, and wildflowers NRCS and WHC, Preserving large populations in large areas: Large and diverse landscapes offering a large variety of microclimatic conditions can support larger and more stable butterfly populations and communities for a much longer time than small areas.

It is one of the most pleasant places for families and visitors to enjoy. So, there is a deep association and this association is strategic and characteristic for the conservation of biodiversity not only for the plant and butterfly species richness but also for the wildlife in the forests. As this association is an indicator for understanding biodiversity status in a forest ecosystem, further studies in the field should be attempted.

There are three categories 32 beds provided for butterfly Mondal, Specimen and stuffing of about species are kept here. The authority has built a herbarium of about types of trees.
The tourists, the students, and the researchers can obtain huge knowledge from this museum. Mainly the park is created for wildlife animals but Butterfly Park is one of the attractive parts of this park.
The gravity Level is so low down for butterfly flying capacity. Here humidity level is not sufficient for butterfly survival. It is not Eco-friendly. The basic plant for butterfly is not sufficient here and most of the plant dies. Plantation process is not done properly Mondal, Here temporary shell is made for butterfly.
Mainly Caterpillars are kept in the shell and are watched them grow up. But most of the butterfly used to die because of Humidity control level. Some photography exhibitions are held in the gallery. Mainly it is for the awareness of the people. With proper conservation measures, we can help them to better cope with ongoing climate change. Wildflower plantings-plantation of wildflower gardens that contain an assortment of native trees, shrubs, and grasses are one of the easiest means of attracting butterflies to an area.
Because adult butterflies rely heavily on nectar as their primary food source. Garden design-wildflower gardens that include taller trees and shrubs behind shorter species can be aesthetically pleasing. Create puddles-providing a source of water in the form of shallow, lined depressions or puddles, small fish ponds, birdbaths or simply a sand-filled bowl buried in the ground will collect water to help attract butterflies to wildflower plantation NRCS and WHC, Besides other initiatives can be taken as follows: Encouraging native legumes dock, milkweed, nettle, and native grasses; Reducing pesticide and herbicide use in agricultural areas when possible NRCS and WHC, Using mechanical means of pest control to minimize loss of nectar-producing trees, shrubs and flowers; Maintaining natural and planted grassland by conducting prescribed rotational burning; Restoring hydrology and vegetation in forested wetlands; Preserving existing trees, shrubs, vines, hedgerows, and wildflowers NRCS and WHC, Preserving large populations in large areas: Large and diverse landscapes offering a large variety of microclimatic conditions can support larger and more stable butterfly populations and communities for a much longer time than small areas.
Nature conservation not only protect existing areas, but also try to extend them and manage them to create large, diverse habitats with strong butterfly populations Van Swaay, et al Encouraging mobility across the landscape: Barriers across the landscape preventing butterflies to shift their ranges in northern direction should be removed as far as possible Van Swaay, et al Gaining time to adapt: Targeted management on the ground should offer existing populations the time to adapt and move to new areas Van Swaay, et al Reducing the emission of greenhouse gasses: Only by a serious reduction in the emission of greenhouse gasses we can expect climate change to slow down, but that should not prevent us from doing what we can do to reduce this impact Van Swaay, et al Researching: To understand what is happening in our continent and improve adaptation strategies in the future, research is a vital instrument Van Swaay, et al Monitoring: Butterfly monitoring is spreading over the continent and more and more countries are with developing schemes.
The schemes not only provide information on the effect of climate change on butterflies, but they also give direct information on biodiversity changes Van Swaay, et al Updating the indicator: Only by regularly updating the indicator we can follow the change of butterfly communities and the impact of climate change on our butterflies Van Swaay, et al Butterfly Park of Bangladesh is the first and only tropical garden in Bangladesh with live Butterfly.
It is one of the most pleasant places for families and visitors to enjoy. So, there is a deep association and this association is strategic and characteristic for the conservation of biodiversity not only for the plant and butterfly species richness but also for the wildlife in the forests.
As this association is an indicator for understanding biodiversity status in a forest ecosystem, further studies in the field should be attempted. As butterflies have got reciprocal relations with the related plants, these plants are dependent on the butterflies for their pollination purposes and gene-flow activities. For this well presence of butterflies ensures the strong status of a forest ecosystem. Undeniably there are innumerable areas that need to be strengthened to get proper conservation and management of butterflies in Bangladesh.
Conservation of butterflies will improve the whole environment for wildlife biodiversity and enrich the lives of people in present as well as in future. Bashar M. Chowdhury, S. Dhaka, Bangladesh.
