Improved water quality

The Wetlands uses natural processes for water treatment and involved local communities in the regeneration of the area. The
Wetlands were constructed in 2005 by diverting a small flow of Chellow Dene Beck through a constructed wetland designed to improve the appearance, water quality and biodiversity of the site. It consists of a series of ponds at the lower end of the site that acts together to remove impurities from the water before returning it to the beck further downstream. The creation of wetlands and maintenance is also a part of the larger Bradford beck project. (reference 1) The site is also used as a recreational trail for the local people and tourists (ref 4). As the reservoir is a local recreational centre it also promotes (paid) recreational fishing activities in some designated spots (ref 5).

Ben Rhydding Gravel Pits Nature Reserve has a variety of habitats. The site is largely artificial, originating from former gravel pits. The river gravels were of good quality and represented an important local source for the construction industry. The pits ceased to be worked in 1970’s and flooded. Infill materials - a variety of materials have been used: building rubble, soil and treated sewage residues from the treatment plants. Plant materials and soil from parks, gardens and building sites have added to the bio-diversity. The reserve is owned by Bradford Council and managed by Wharfedale Naturalists Society volunteers. (reference 1) With the support of Natural England, the site was declared a Local Nature Reserve in October 2013. (ref 7).

The Sun Lane nature reserve in Burley-in-Wharfedale is the second site in Bradford to receive the Local Nature Reserve (LNR) status. The land was used as a garbage dump and reclaimed in the 1970s. (ref1) Pollution from the landfill site was leaching into nearby watercourses and in 1993, Bradford Council undertook a scheme to cap the landfill and restore the site. They installed a reed-bed purification system, to eliminate pollution from contaminated water and add to the reserve’s biodiversity. The Burley Village Wildlife Group began conservation work to enhance biodiversity. (ref4) In 2003 a group of volunteers took over the maintenance of the area and now help to manage it in collaboration with Bradford Council (ref 5). As the site heals at its best, forty-two Common Blue butterflies were recorded together in 2006 (ref 5).

The once rich in fish Nidda river in the north of Frankfurt was canalized and dammed in the 20th century. River loops were pierced, filled in or made into oxbow lakes. Newly built weirs stopped the fish migration. The expansion provided good protection against flooding, but the river became a canal (2).
In the 1990s, the Nidda neighbours developed a program for the renaturation of the river, the concept "Natural Nidda". It was decided by the city council of Frankfurt am Main in 1998 (2). The project consisted of many measures aiming at the restoration of the natural course and ecosystem of the Nidda river, the creation new habitats for flora and fauna, the expansion of the floodplain area and thus the river's retention capacity, the deconstruction of weirs, the renovation and building of bridges and the reconnection of disconnected branches of Nidda. Besides the environmental aspects, another project goal was to make the riverside more accessible for local offering various ways for relaxation and recreation. (2,7)

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).

In their application for funds from the city’s participatory budget, the citizens introduced the cleaning of the river Glowna (riverbed and riverbank) in Poznan along the entire length of the river within the city area (excluding private and inaccessible areas). The initiative aimed to clean the stream and to increase the attractiveness of the riverside. The action was implemented with the voluntary help of the residents as a way of promoting ecological behaviours [1].

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).

The project revitalized beaches around three lakes near Poznan: Kierskie, Strzeszynskie, and Rusalka. Over 1000-ha of forest and three lakes located within the city borders make this a unique recreational area for the inhabitants of Poznan and its surroundings. The project aims to modernize the neglected beaches and build basic infrastructure and communication paths. The plans involved cleaning of the area, planting greenery, regulation of the lake beachline, introducing environmentally friendly solutions (e.g. solar lamps), open-air playgrounds and gyms, and renovation/installation of the new bridges over the lakes [1].

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 restoration of the Nesttun watercourse was made in order to secure the watercourse’s surroundings against damaging floods and to develop its urban qualities as a blue/green structure traversing this part of the city. The City of Bergen has exploited possibilities in flood control measures to develop the watercourse’s natural qualities and improve accessibility. A number of measures were completed in order to give the watercourse a positive ecological status and make it into an attractive recreation corridor, learning arena and secure ‘blue-green’ urban structure.
