The importance of wetlands for migratory birds
The importance of wetlands for migratory birds
in wetlands
wetlands consisting of swamps, bogs, rivers and lakes are among the most productive ecosystems in the world. They are biologically diverse areas and serve as a habitat for numerous animal and plant species. In addition to their ecological importance, wetlands play a significant role in water regulation, they act as natural filters for polluted water and contribute to carbon storage (Wetlands International, 2020). Within this multi -layered network of nature, wetlands are particularly crucial for migratory birds.
Why are wetlands important for migratory birds?
Migratory birds represent some of the most remarkable phenomena in the wildlife. Every year these types cover thousands of kilometers to escape the cold and have access to rich food sources. However, such epic travels are not without challenges, and this is where wetlands come into play.
shelter and breeding grounds
Wetlands offer important resting and resting places for migratory birds during their strenuous journey. They provide shelter, food and water that birds need to recharge your batteries and continue their way. In addition, wetlands are ideal breeding grounds for a variety of migratory birds.
Many species, including swans, ducks and geese, prefer to lay their eggs in wetlands. The dense vegetation offers protection against predators and the rich range of insects, snails and water creatures ensures adolescents of adolescents an adequate supply of food (Ramsar Convention, 2006).
food sources
Wetlands are rich in food sources that are decisive for the enormous energy requirements of the migratory birds. Flooded rice fields, swamps and wetlands are full of various insects, fishing, crustaceans and plants. Some birds, such as the green leg and the gray shop, are heavily dependent on the food sources they find in wetlands.
Danger from wetland destruction
The destruction and loss of wetlands, mainly due to the change of land use by humans, have profound effects on the global bird populations. Without sufficient rest areas and food sources on their route, birds have to fly further to find suitable habitats, which increases their energy needs and reduces their chances of survival (World Wildlife Fund, 2018).
effects of climate change on the wetlands
Climate change changes the balance of ecosystems worldwide and represents an additional threat to moisture areas. By increasing global temperatures, moisture areas can dry out or salt content and water levels can change, which makes living conditions difficult for many plants and animals (IPCC, 2014).
Effects on migratory birds
The changes in the wetlands caused by climate change affect the migratory birds directly. Changes in vegetation and the availability of food can affect the ability of the migratory birds to build up enough energy for their long flight. In addition, changes in the seasons and climate can affect the reproduction of migratory birds by changing their breeding pages and thus the chances of survival of their descendants (North American Bird Conservation Initiative, 2010).
protective measures for wetlands and migratory birds
In view of the crucial importance of wetlands for migratory birds and the environment in general, their protection is of great importance. There are various strategies and measures that can be taken to ensure the preservation of these sensitive ecosystems.
Legal regulations and international agreements
One of the most effective measures to protect the wetlands is the creation of legal regulations and international agreements. Examples of this are the Ramsar Agreement and the Bonn Convention, which concentrate specifically on the protection of wetlands and migratory birds (Birdlife International, 2015)
Local efforts and community management
Local communities play an important role in the protection of wetlands. Through sustainable land use practices and the involvement of the community in protective efforts, wetlands can be obtained effectively.
conclusion
The importance of wetlands for migratory birds cannot be assessed high enough. They are crucial for the survival of millions of birds that rely on their resources during their epic migration trips. With increasing threats from climate change and the loss of habitats, we have to make increased efforts more than ever to protect these essential ecosystems. Because the protection of the wetlands not only means the protection of migratory birds, but also promotes a richer and more diverse nature for everyone.
