The value of urban gardens for biodiversity
urban gardens are oases of calm and peace in the middle of the hectic city drive and not only offer residents, but also a variety of animals and plants. The value of a garden for biodiversity is much larger than one would take at first. In this article we will deal with the diverse importance of urban gardens for the local and global ecosystem.
biodiversity in urban gardens
What is biodiversity?
Biodiversity, also called biological diversity, refers to the variety of life on earth. It contains variations within species, between species and ecosystems. It plays a key role for the smooth functioning of ecosystems, since every animal and every plant plays a special role in the food chain and contributes to the balance of the ecosystem.
The contribution of urban gardens on biodiversity
Urban gardens are often more diverse than natural ecosystems because they can contain a wide range of plants, trees and shrubs that come from different parts of the world. This diversity can attract a variety of animals such as birds, insects and small animals that find food and refuge within the garden.
In addition, urban gardens are important to create corridors for the wildlife in an urban environment. They offer animals, in particular birds and insects, secure thorough zones between natural habitats that have been interrupted by urban development.
The role of urban gardens in the preservation of biodiversity
Creation of micro -based
Through targeted design and care, urban gardens can help create microbitats that serve certain species as a habitat. For example, dead wood piles or dry stone walls can offer shelter and food for a variety of insects. Oppress gardens, on the other hand, can represent a replacement habitat for plant and animal species that can hardly find habitat in the other urban environment.
promotion of rare and endangered species
Many domestic plant and animal species, including some rare and threatened species, find a home in urban gardens. By creating suitable conditions, these gardens can contribute to the preservation and spread of these species. For example, the sowing of wildflower meadows can help insects such as bees, butterflies and beetles, which are endangered by the loss of habitats and the use of pesticides.
urban gardens and climate change
The role of urban gardens for biodiversity is not only important for the flora and fauna, but also in the context of global climate change. Gardens can help to reduce the negative effects of climate change and to make cities more resistant to these effects.
carbon storage
Trees, shrubs and plants in urban gardens contribute to reducing the CO2 content in the atmosphere, since they bind carbon through photosynthesis. Studies have shown that urban green, including gardens, street trees and parks, can make an important contribution to carbon storage.
heat capacity
The dense development and the high proportion of sealed areas lead to a phenomenon in cities that are called "Urban Heat Island Effect", in which the temperatures in urban areas are higher than in rural areas. Gardens can help to reduce this effect by offering shadows and contributing to cooling the environment through evaporation and transpiration.
tips on promoting biodiversity in urban gardens
There are many simple and practical steps that every garden owner can take to promote biodiversity in his own garden.
selection of local plants
Local plants have adapted to the local conditions and often offer the most suitable food and the most suitable habitat for native animals. By selecting local plants, garden owners can ensure that they make a contribution to supporting local biodiversity.
Provision of nesting places and food sources
The installation of birdhouses, insect hotels and feed stations in a garden can help to offer a safe place to nest and eat.
Reduction of pesticide use
Pesticides can be harmful to many animals, especially for bees and other polluting insects. By reducing or doing without the use of pesticides, garden owners can help protect these animals.
conclusion
Urban gardens are more than just attractive, green areas in our cities. They play a crucial role in promoting biodiversity by offering plants and animals habitats and food sources. In addition, they help to mitigate the effects of climate change and make our cities more resistant. Every garden, no matter how small, can contribute to the protection and promotion of biodiversity. With a little knowledge, use and love of nature we can transform our gardens into real biodiversity havens.
