Facade greening involves planting climbing plants or other plant species on building facades. This improves the appearance of a building and thus enhances the urban environment. 

Facade greening also offers numerous ecological benefits. The plants absorb carbon dioxide and other pollutants from the air, helping to improve air quality. They also act as a natural noise barrier and help to reduce the ambient temperature by absorbing heat and generating evaporative cooling.

Green facades can also help to reduce the building's energy consumption: the plants form an additional layer of insulation that reduces solar radiation in summer and heat loss in winter. This can reduce the need for artificial air conditioning and heating.

In addition to the ecological benefits, facade greening also has a positive effect on people's well-being. The green environment has a calming and stress-reducing effect. It also provides a habitat for birds, insects and other animals, which helps to promote biodiversity in urban areas.

Green roofs are planted in the form of roof gardens. This creates a new habitat for plants, animals and insects. These roofs create a green retreat in urban environments where natural habitats are often scarce. They provide shelter and food for birds, butterflies and bees, for example.

Other benefits of green roofs include improving air quality: plants absorb CO₂ and release oxygen in the process. In addition, green roofs contribute to thermal insulation and thus lower the temperature in the building and the surrounding area, which reduces the urban heat island effect. They also act like a sponge by storing rainwater and thus relieving the burden on the sewage system, which can prevent flooding. In the long term, green roofs also extend the service life of the roofing material because they protect it from extreme weather conditions. In addition, green roofs enhance the aesthetics of buildings and create recreational spaces for people.

Sand grassland is a special type of dry grassland that grows on sandy, nutrient-poor soils and is characterized by open, often sunny and dry areas. 

Sand grassland is widespread in Central Europe, especially in countries such as Germany, the Netherlands and Poland. The “Sandachse Franken" (Franconian sand axis) runs through the middle of Nuremberg, an area that provides a habitat for many rare animal and plant species. These areas are of particular ecological value as they are home to a wide variety of species. For example, various species of butterflies, grasshoppers, reptiles and rare birds live here. Seed-eating birds such as the goldfinch and the tree sparrow also find food here in the seed-rich plants.

Typical of sand grassland are small grasses, herbs and dwarf shrubs that are adapted to the demanding conditions, such as sand sedge, sand thyme, hawkweed and sand strawflower.

Unfortunately, sand grassland are severely threatened by intensive agriculture and urban development. Various measures such as careful grazing, mowing or the removal of woody plants help to preserve and restore these valuable habitats. wbg Nürnberg is actively committed to protecting these sandy grasslands in order to promote biodiversity and preserve nature.

Deadwood are pieces of dead wood such as branches, trunks or tree stumps that remain in an ecosystem and thus form a valuable habitat. Although the wood no longer transports sap, pieces of dead wood play a crucial role in various larger ecosystems and fulfill several functions: Deadwood is an important habitat for a variety of organisms such as microorganisms, lichens and fungi, insects, birds, small mammals and other animals. Some species are specifically dependent on deadwood for nesting, feeding or completing their development cycle.

Deadwood also contributes to the nutrient supply of the soil by slowly decaying, forming organic material and releasing important nutrients. This process promotes the growth of plants and other organisms in the surrounding area.

As deadwood is therefore an essential component of healthy ecosystems and contributes to biodiversity, it is important for wbg to leave branches, cuttings, tree trunks and roots in the neighborhood in order to improve the nutrient cycle and thus ensure the stability of habitats.

In addition to its functional value, deadwood can also have an aesthetic value, for example by using old tree stumps as natural decoration or seating.

Visible successes:

Deadwood on wbg's green spaces is already serving to connect habitats for a variety of animal species. Shortly after the deadwood areas were created, it became clear how well the wildlife is thriving in its new environment.
