Habitat and biodiversity conservation

In September 2011, a new eco-friendly student village ‘The Green’ opened to students at the University of Bradford. The new eco-village "The Green" has been designed to incorporate a range of features to enable students to live in a more sustainable way. It is part of a broader sustainability initiative by the University of Bradford called 'ecoversity' and its development is clustered around a pond, which is a part of a sustainable urban drainage system (SUDs). The Urban Pond/biodiversity pond – at The Green increases the biodiversity of the site. The site has been designed and landscaped with nature in mind, consisting of grassed areas, a wildflower border, shrubberies and native trees. (ref 3) The £30.4million development was the first multi-residential building in the UK - and one of only 15 buildings worldwide (ref 7).

The project area comprises the morphological floodplain of the Rhine to the north and south of the city of Karlsruhe and sections of the river Alb, covering an area of about 7.665 hectares in total. Alongside Karlsruhe, five smaller communities in the neighbourhood contribute to the project as partners. Due to the channelling of the Rhine, the construction of dykes and the isolation of river channels, the area has lost its natural floodplains and precious habitats and became more vulnerable to flooding. Major objectives of the project are the re-introduction of natural floodplains and the enhancement of natural habitats for local flora and fauna. (Ref. 7). The project included an exceptionally wide range of measures including species protection measures, the complete desludging of parts of the Rhine, the re-establishment of softwood and hardwood forests typical of the floodplain, the construction of bridges, the natural remodelling of the entire river Trench systems and the creation of new bodies of water. (Ref. 9) The project also provides environmental education, informing the public about activities and encouraging their participation (Ref. 7)

Vine Court is a student residential complex located at the heart of the University’s city campus. It is equipped with both green and brown roofs, providing environmentally friendly habitats for local flora and fauna, utilizing local plant mixes and building material rubble from the excavated site. (Reference 2). It is at the forefront of sustainable residential development in the UK higher education sector and it was built to a high standard of sustainable design and energy performance. In addition to the eco-technologies incorporated into the structure, the brickwork includes built-in nest boxes for swifts and bats. It has been awarded a design stage BREEAM Excellent certification (Reference 1).

The Mab Lane Community Woodland was planted on a former playing field at Mab lane and Croxdale Road West in Liverpool. It is a part of the larger Mersey Forest initiative which has been increasing the amount of woodland and green spaces across Cheshire and Merseyside since 1991.
The new woodland which has a network of native trees, wildflower meadows a community orchard as well as seasonal wetland areas and footpaths, was officially opened by the local community in 2010. It also includes new pathways for walkers and cyclists and areas for family picnics (Ref. 2, 10). Mab Lane Community Woodland is a partnership project involving the Forestry Commission, Northwest Development Agency, Mersey Forest, Big Lottery, Riverside Group, Liverpool City Council and the Local Community (Ref. 10).

The project BEETE & BIENEN (Beds & Bees) in the Eastern part of Karlsruhe is an awarded sustainability experiment where garden beds, flower beds and beehives create a new urban greenspace for humans and animals and increase the urban bee population. Residents - in collaboration and under the guidance of gardeners – plant herbs, flowers, vegetables, fruits and trees that provide food for humans and thereby provide a natural habitat for the urban bee population to thrive. Residents shall take over ownership of maintenance and cultivation of the garden in the long run. (Ref. 1). The project is not about honey yield, but about enabling the bees to live as naturally as possible. Hives and garden beds are established in several small gardens in the city, including one Marstallgarten and another in Grötzingen. (Ref. 8)

46.5 hectares of nationally-important habitat was restored in Doncaster as part of an Environment Agency-led project benefiting communities and wildlife. The work across seven woodland areas was designed to help improve water quality, reduce flood risk, and enhance natural habitats for protected species. By providing additional flood storage the project is able to help attenuate both peak and flood flow from rainfall events, reducing flood risk and damage and reducing the financial and carbon cost of pumping water from the Torne catchment. Although this project extended beyond Doncaster, Sandall Beat in Doncaster was part of the key sites (Ref 1).

In 1995 the city of Munich decided to implement a new green residential district in the derelict area of the former Munich-Riem airport which was closed in 1992. (Reference 9) The area was designed to have an intensively used residential area in the north and an extensively used green recreational area in the south. The project was completed in 2005. It is 210 hectares large, making it the third-largest public park in Munich. (Reference 1) The park includes a 10-hectare large artificial lake, a 15-hectare large forest and two 20 meter high artificial observation and toboggan hills made from the demolition material of the former airport. (Reference 9) The park is appreciated by people but concerns about the loss of biodiversity have been raised. Citizens use the park for walking, cycling, swimming in the lake or simply for relaxation. (Reference 4)

The Green Belt in Frankfurt am Main spans in the inner area of the city and covers almost a third of the city's wider area which is around 80 square kilometres, around half of which is the city forest (6). In 1991, as stated in the city council's Green Belt Constitution, the Belt has been declared a protected open space while it also outlined the long term goal of securing and developing it (1). The green belt with its landscapes, excursion destinations and the large network of paths is important for the quality of life in Frankfurt and at the same time offers a place of retreat for plants and animals. It is essential for a good urban climate (1).

The Desjoyaux ZAC in the Crêt-de-Roc district, was created in 2005. Since then, this three-and-a-half-hectare site, which is involved in the process of receiving the "eco-district" national label certification since 2015, has metamorphosed (Ref. 1). Some works aim to renew and embellish the public spaces located near the residences of the street and the impasse Desjoyaux to preserve biodiversity in the city center of Saint Etienne and for the well-being of citizens. (Ref. 1, 2 and 3). Community gardens, park, ephemeral gardens, swales and sustainable water filtration system are being developed in this project (Ref. 1, 2 and 3).

"On June 1st 2017, Saint-Etienne Métropole officially committed itself to the implementation of measures to promote the circulation of wildlife between the different green spaces with important biodiversity in its territory" (Ref. 3). "Saint-Etienne Métropole has signed with 13 partners a new contract called "green and blue". It is a new blue and green framework for the whole territory, a regulatory tool for the protection of biodiversity" (Ref. 2). "It aims to continue and reinforce the actions already undertaken with a transversal and urban dimension" (Ref. 2).
