Ecological restoration of ecosystems

New recreation zone "Norikus Bay" in Nurenberg was completed in 2018 on the south bank of the Wöhrder lake, an artificial lake created in 1968 to protect the city from flooding. The dam itself, which is a 400m long path separating a part of the water surface from the bigger part of the lake, has become a tourist attraction with a water playground and other recreational amenities being offered. The water is naturally cleaned through the regeneration zone with natural plant filter, and simultaneously improves the habitat of fish and makes recreational swimming in possible in the cleaner water. New green areas are organized on the shore in order to improve environmental, aesthetic and recreational conditions of the area (1, 7, 8).

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)

The Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust (BBOWT) 'Water Vole Recovery Project' is working in partnership with the Environment Agency, the Canal & River Trust and Thames Water to monitor water voles. Water voles have undergone one of the most serious declines of any wild mammal in Britain during the 20th century. The intensification of agriculture in the 1940s and 1950s caused the loss and degradation of habitat, but the most rapid period of decline was during the 1980s and 1990s as American mink spread. Between 1989 and 1998, the population fell by almost 90 percent! The above project also is identifying habitat enhancement opportunities and influencing local landowners to manage sites sympathetically for water voles and implement mink control. (Ref. 1)

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)

The acronym VERDIR stands for Sustainable Rehabilitation and Responsible Innovation (Valorisation de l’Environnement par la Réhabilitation Durable et l’Innovation Responsable) and is a project of the University of Liège, about the development of local economic activities based on urban and peri-urban agriculture. It aims to convert existing brownfield sites according to the needs of the population. This involves the large-scale production of vegetables and plants which can be used for food but also for the pharmaceutical industry and the production of biomass, which is increasingly needed (Ref. 1).

Until the 1990's Bidston Moss was a landfill site and was "unsafe for public access", thus giving a negative impression (close to several residential areas). Restoring work begun in 1995, and in 2006 development started in Bidston Moss through a Newlands scheme: including new features and landscape enhancements to “unlock the full potential” of the area (“as a valued and well-used community woodland for local people and wildlife.”). (Ref. 1, 2)

The association Legambiente Catania has presented a project to protect and enhance the biodiversity of the Cibali forest, a natural reserve in Catania close to the volcano Etna. The area has been subjected to strong anthropogenic pressures in the last decades, and the area is home of several species of flora and fauna. The main aim of this intervention Is to protect endangered species and to preserve the services the forest provides in terms of air quality regulation and heat mitigation. In addition, the entire zone is a cultural heritage for the whole island (Ref.1.)

North Wirral Coastal Rangers and volunteers are working together to plant discarded Christmas trees to stabilise sand dunes between Leasowe Bay and the Gunsite area of the North Wirral Coastal Park. The Christmas trees help to catch and trap sand blowing in from the beach and in a few years will create artificial dune shapes, benefiting plants and animals. (Ref. 1)

In 2016 the Rangers and volunteers undertook a dune restoration project at the Gunsite. They advertised for the public to drop off their old Christmas trees at a collection point. The trees were then used to reinforce the dunes and trap sand. This was very successful and in 2017 they continued with the project, again with great success. In 2018 they ran a high profile social media campaign using Twitter and Facebook, asking for more Christmas Trees. This has generated a huge response and generated over 900 trees. It also prompted Radio Merseyside to interview Dave Stevenson, the Coastal Ranger, over the project and how it was helping to stabilize and re-establish the dunes (Ref 8).
