Protection of natural ecosystems

Pegnitztal West is a new corridor and recreation zone along a section of the Pegnitz river in Nurnberg suitable for all kinds of social groups and intended for recreational activities (1). The project instrumentalizes green and blue infrastructure for creating conditions for sport, leisure, and recreation, as well as serving a transitional function for the dwellers of the neighboring Gostenhof and St. Johannis districts (1). The green corridor also provides a protected urban habitat for various species, including more than 8 different tree species, water bats, green woodpeckers and swamp warblers. The project also stabilized the water level of the river and helps flood protection efforts. (2, 7)

View Island in Reading is a relaxing island with natural open space with grassy paths and seating near to the weir at Caversham Lock. A conservation project has been carried out to e.g. improve water flow, improve biodiversity, and improve the entrance to and around the island. The work has been carried out in consultation with Reading Borough Council, the Environment Agency and has been designed and constructed by Riverworks Ltd. (Ref, 1, 2, 3)

In 1958 the former marsh "Hellmansbruch", a botanical and zoological jewel, was drained to build the motorway junction Wuppertal North. Since 1990, the working group Nature and Environmental protection (ANU) which consists of volunteers, has maintained a protected landscape area of 3 ha (remains of the former marsh) with the regionally highest density of moorland spotted orchid in the middle of the transport junction. Based on continuous mostly manual maintenance work, such as cutting back encroaching bushes, the large orchid population could be protected and the green space area in total even increased, becoming a biodiversity hotspot. (Ref. 3 and 7). The project also includes the protection of endangered flora and fauna native to the area, including endangered amphibians. (Ref. 7) Guided tours are also offered to visitors of the "nature paradise" in order to raise awareness about indigenous and threatened nature. (Ref. 3).

From 2006 onwards, the urban stream Wupper and its riverbanks were redeveloped and ecologically improved via several water management and planning measures across the city of Wuppertal. Initiated by the city administration and the public sector company Wupper, they aimed at improving the environmental- and water quality or the area and enhancing biodiversity in and around the Wupper. These efforts were accompanied by additional citizens' initiatives with the same goal. (Ref. 1, 2, 3, 9). According to the EU Water Framework Directive, 27 percent of the Wupper and its tributaries are now in good condition, which is well above the German average of 8 percent. The complete renaturalization is planned to be completed by 2025. (Ref. 12)

Fobney Island in Reading (which is an area by the River Kennet in Berkshire county) was transformed through a restoration project in order to e.g. attract wildlife (birds; bats; water voles; otters). This partnership project (with work being carried out by the Environment Agency, Reading Borough Council, Thames Water and the Thames Rivers Restoration Trust), includes restoring the river and creating wetlands. (Ref. 1-3)

This NBS is implemented on a nature reserve site, Ciuperceni-Desa, a protected area that has habitat types with natural eutrophic lakes, oligotrophic seawaters, panonic salty marshes, sandy panonic meadows, low altitude meadows, clusters of walnut vegetation and white poplar and cultivated arable land. In 2016 the Romanian Government alongside an NGO developed a plan for its protection and conservation since locals complained that it is not taken care off accordingly, that the area became a dump for people to trow their garbage and that it affects the species (1, 2)

"Formerly a 10 hectare market gardening site, the Repainville area is rich in environmental potential: ponds, streams, springs ... the aquatic environment is present everywhere. There is a great variety of fauna and flora. As an ecosystem that is particularly rare in urban areas, protection and recovery measures are being undertaken" (Ref. 1). The restoration of the wetland of Repainville is part of a flagship project of the municipality in terms of safeguarding biodiversity in urban areas. With arrangements allowing the public to walk there without harming the biological and natural diversity of the place, the site has an educational dimension in order in particular to make young audiences aware of the preservation of the ecosystem (Ref. 7).

The 'Painting The Town Green' project worked in urban and suburban areas of Medway, Swale and Thanet. They improved or created green spaces in these areas, adding color and enhancing biodiversity together with locals from many different backgrounds. They specifically worked with schools, nurseries and community groups to improve neglected environments. The project aimed to increase participants' well-being as well as leaving improved spaces for local communities to enjoy (ref. 1).

A living green wall packed with plants including primula and thyme was the latest addition to the university's Medway Campus. It was part of a university research project that assessed the benefits of small-scale living walls (ref. 1).

The Natural Park of Collserola (about 8,000 ha) is a forested area in the hilly Northern fringes of Barcelona. Since 1987, Collserola has been managed under a special protection plan and forms part of the European FEDENATUR network that aims at protected fragile peri-urban ecosystem for both their social and ecological functions. The park is jointly managed by a consortium including the Catalan government (Generalitat de Catalunya), the Barcelona Provincial Council (Diputació de Barcelona), the Metropolitan Area of Barcelona (AMB) as well as all adjacent municipalities (Ref 1).
