Why are salt margins so important?

salt meadows are ecosystems that are located in transition zones between the country and the sea and play an important role in the earth system. Their worldwide distribution makes them an indispensable part of global biodiversity and they make a significant contribution to maintaining planetary health. But why exactly are salt meadows so important? The answer lies in its unique ability to store carbon dioxide in its role as a habitat for a variety of animal and plant species and as natural coastal protection. These aspects make the salt marshes an extremely valuable ecosystem, both from an ecological and economic perspective.

The ecological meaning of salt marshes

carbon storage

Salms are excellent carbon storage. You can effectively bind and save carbon dioxide - a greenhouse gas that contributes significantly to global warming. They are one of the so -called "blue carbon sinks", which have their names due to their ability to convert carbon into biomass through photosynthesis and produce oxygen. This happens in photosynthesis when plants absorb carbon dioxide from the atmosphere and convert it into glucose, which they then use as an energy source.

biodiversity

Salt meadows are also hotspots of biodiversity. This means that they are home to a variety of animal and plant species- including many endangered and protected species. Sea birds, insects, fish and mammals are dependent on this unique environment, which offers them food, shelter and spawning spaces. Salt meadows are also important resting places on their long trips for migratory birds.

water quality

Salt flies also contribute to improving water quality. The plants and the bottom of the salt marshes serve as natural filters for the surface water flowing into the sea. They hold back sediments and pollutants - such as heavy metals or pesticides - prevent them from getting into the sea.

The economic meaning of salt marshes

natural coastal protection

Salzwiesen act as natural coastal protection. They dampen the force of the waves and thus reduce the erosion of the coast. This aspect is particularly important in times of climate change and increasing sea level. According to a study by the Nature Conservancy, Salzwiesen protect the coastal regions a year ago over $ 625 million damage caused by storm surges.

fishing and aquaculture

Salms are also of great importance for fishing and aquaculture. They serve as spawning spaces and nursery for many types of sea animals - including economically important fish and crustaceans. The healthy and productive function of this habitat is therefore also essential for the yield of fishing and aquaculture.

natural tourism

In addition, salt meadows offer diverse recreational opportunities and are an attraction for natural tourism. Hiking, watching birds or just enjoying the calm and beauty of nature - these are just a few of the activities that people can enjoy in salt marshes. The value of this "ecotourism" can be in the millions and is an important factor in local and regional economic life.

conclusion

The importance of the salt marshes can hardly be overestimated. You play a crucial role in the general health of our planet by saving carbon dioxide and thus contributing to combating climate change. They are home to a variety of animal and plant species and contribute to improving water quality. They so protect Our Coasts from erosion and serve as vital spawning grounds for many marine species. And they generate significant income from tourism, fishing and aquaculture. Despite their enormous importance, salt marshes are still threatened worldwide, especially through climate change, land use and pollution. Urgent measures are required to protect and restore these unique ecosystems that provide such essential services for us and our planets.
