Green space and habitat

The city of Salford has experienced several floods and is at risk of flooding once every 100 years (Ref1). The majority of properties in the city that lie in a high-risk flood zone are in the floodplain of the Irwell. The UK's Environment Agency and the council, designed a flood prevention scheme which included temporary water storage areas which will store floodwater on the existing Castle Irwell playing fields and public open space, and double as sports area otherwise (Ref 5). It aimed to have its own wetland and wildlife habitat, and will help protect hundreds of homes and businesses (Ref 4).

The Environment Agency, Manchester City Council and the Irwell Rivers Trust had undertaken works to renaturalise a section of the River Medlock running through Manchester. The project had sought to return the river to its natural state by widening the channel and replacing the Victorian brick lining with gravel that provides a more natural-looking and fish-friendly section of the river and reduces flood risk at the same time (ref. 3). The project was also being seen as an EU exemplar of how to go about restoring an urban river (ref. 1, ref. 7).

The Revealing the Roch project uncovered two sections of the River Roch to expose a historic bridge which had been hidden for over 100 years (ref 1). Re-opening and deculverting the River Roch and bridge has a tangible benefit by reducing flood risk for the town (ref 4). The scheme, which is a key part of Rochdale town centre’s ongoing regeneration programme will help reduce flood risk in the town center and create educational opportunities. The project also includes enhancing the natural heritage of the river by introducing features that encourage river vegetation and creatures to re-establish themselves (ref 5). The project has since led to a wildlife boost, with brown trout, bullhead fish, heron and kingfishers all being seen since construction work to open the river began. (Ref 3). As the River Roch connects to River Mersey which empties into the North Atlantic ocean, this intervention addresses marine ecosystem restoration as well.

New Bolton Woods Ltd is a development partnership between the regeneration company Urbo and Bradford Council (ref5). This project aims to create a new sustainable urban neighbourhood, linked to the existing Bolton Woods. As the majority of the proposed development is situated on land which falls within Flood Zone, a range of measures including the raising of ground floor levels, and incorporation of sustainable drainage techniques will be used to manage runoff.
The project intends to provide a series of well landscaped, high-quality open areas and parks for the community. There is potential for a long term phased canal restoration (ref. 1). The second stage,145 houses are currently under construction on the slopes off Poplars Park Avenue, overlooking Canal Road, and are due to be completed by 2021 (ref 6). West Yorkshire Ecological Service raised concerns that the development would lead to a loss of woodland (ref 6).

Arcosur is a new residential neighbourhood project approved for construction in 2008 after the hosting of the Zaragoza Expo 2008. In its structure, it seeks to develop a space of 4 500 000 m2 into around 21 000 new homes, and out of which around 1 500 000 m2 will be squares, parks, and other green spaces. These green spaces would connect the neighbourhood and ensure all residents have access to green areas. (Ref. 1)

Coal mining in the Dearne Valley damaged the Dearne Valley landscape. To address these problems the Dearne Valley Green Heart partnership was formed in 2006, but the intervention discussed here is specifically related to the developments between 2012 and 2015, when it was founded as a Nature Improvement Area. It is part of the South Yorkshire Delivery Programme and part of the Doncaster Council as also being part of the Doncaster Green Infrastructure Strategy (Ref 1, 2).

The Connswater Community Greenway has created a 9km linear park project in East Belfast following the course of the Connswater, Knock and Loop Rivers, connecting the open and green spaces. As part of the project the Connswater River will be cleaned and brought back to life. The Greenway will create attractive, safe and accessible parkland for recreation and community activities. The project will improve the quality of life for the people of east Belfast as a whole new greener environment will emerge. (Ref1)

Connswater Community Greenway is a visionary urban regeneration project that is transforming East Belfast by combining improved flood protection with the creation of public spaces and pedestrian/ cycle routes that connect communities. (Ref 6)

The Carbon Landscape is a pioneering project in landscape restoration in Wigan, Warrington and Salford. Led by the Lancashire Wildlife Trust, it will revitalize a landscape left devastated by decades of coal-mining and peat extraction (Ref 5). It works to restore key habitats and reconnect local people with their unique natural heritage, preserving it for future generations. The restoration of the peat base to lowland raised bog provided an opportunity for carbon sequestration and storage (Ref 1). There is a strong vision to reconnect local people with their rich natural heritage, creating opportunities and a sense of pride in the local area (Ref 4).

City of Trees is an innovative movement set to re-invigorate Greater Manchester’s landscape by transforming underused woodland and planting a tree for every person who lives there (ref 1). Manchester City of Trees had undertaken work to improve water quality of a tributary of Worsley Brook through channel naturalisation and create wet woodland in the Cleavleys Nursery. The discharge from the tributary caused water quality failures in Worsley Brook under the Water Framework Directive (WFD) (Ref 3). This project allowed the stream to take a more natural course through the woodland and the waterlogged woods provide habitats to species and remedy these water quality issues (Ref 3).

The roof installation at the Re:center building comprises of a wildlife pond planted with native marginal plants, a native wildflower area, grasses and herbs, bird feeder tables, insect houses etc. Design features encourage the development of flora and fauna on the roofing area and a growing media (from ABG) provides a nutritionally rich base for vegetation. Beneath this surface, a free-draining void allows for storage of collected rainwater to irrigate the vegetation. This roof is part of the Bright Building at the University of Bradford. (ref2) The building was known throughout its building phase as The Sustainable Enterprise Centre, but it is recognised that thinking around sustainability has moved considerably since this project started back in 2007 and the new name will ‘re:flect’ new agendas in a way that is distinctive within Higher Education (ref 6).
