Green space and habitat

Following an extreme flood event on August 9th 2008 in Glendhu Park, eight houses experienced flooding and many more came within inches of being flooded. Two swales were constructed by Dublin City Council to provide surface water storage to ensure that no flooding will recur in a similar 100-year pluvial event. The swales are designed to self-drain back into the existing surface water sewer system following a severe storm event (Ref. 1).

Lodge Hill is a nature area allocated to become a settlement capable of delivering approximately 5000 dwellings by 2028 (original plans). Green infrastructure is a key component of the current plans and specific GI implementation will be based on the existing GI assets. Specifically, the plans include green corridors, sustainable urban drainage systems (SUDs), various parks and street greenery, community allotments, buffer zones around sites of special scientific importance (SSSIs) and woodland (Ref 1).
The plans for Lodge Hill have been controversial, as Chattenden Woods and Lodge Hill Site of Special Scientific Interest (SSSI) is a nationally important area of ancient woodland and rare grassland that supports one of the largest populations of nightingales in the UK (Ref. 7, 8, 9).
In 2018 Kent Wildlife Trust started a campaign (#SaveLodgeHill) to ask Medway Council to not to allocate Lodge Hill development, which has resulted in a scaled-back version of the original plans for Lodge Hill from the construction of 2,000 to 500 houses, avoiding any direct loss of the Site of Special Scientific Interest - which will still have an impact on the nightingale's population (Reg. 7).

The former Paulsgrove landfill is being developed into the Horsea Island Country Park to address the deficit of public open space for Portsmouth’s residents (3). The council plans to put in place a number of initiatives to make sure the country park is a recreational facility and attracts a diverse range of wildlife. This is being progressed through the PUSH Green Infrastructure Implementation Plan. (1). Veolia, the company that operated the landfill site on Horsea Island has the responsibility for implementing the landscape proposals which include tree planting, grass areas, wildflower meadows, footpaths and cycle routes. (2).

Owing to the city’s participatory budget, the residents created a well-equipped green recreational square in a vacant area of one of Bydgoszcz's neighbourhoods. The initiative involved the creation of an outdoor gym with several exercise equipment stations, as well as planting pollution-resistant trees and bushes - including oaks, maples, pine and spruce. The initiative aims to manage vacant space and increase access to the green space in this city district [1].

The initiative was funded from the participatory budget of the city and resulted in planting new greenery (including 70 trees and a thousand shrubs) by the local city lake 'Balaton' in Bydgoszcz. The justification of the project in its proposal highlights the practical and aesthetic values of green areas [1].

Southsea Green community garden was developed from a derelict strip of land, to encourage more local growing and spread the message about gardening and volunteering. With time, the garden has transformed into a community green-space (1). Southsea Greenhouse is a collective of gardeners and crafters. The Greenhouse Community Co-operative is transforming wasteland into a community garden and re-investing profits from sales of produce and crafts, back into the local community. Community events and workshops are offered to encourage sharing of local skills and resources, foster a love of the city’s greenspace, and care for wildlife. (3)

Milton Common is the second stage of the multi-million-pound Flooding and Coastal Erosion Risk Management scheme being developed across the north of Portsea Island, from Mountbatten Centre round to Milton Common. The overall project will reduce the risk of coastal flooding and erosion and provide the critical infrastructure the city will need over the next 100 years (6).
As the second phase, Milton Common included the instalment of a new rock revetment as a plans defence, the creation of a coastal path and three new earth bunds with new footpaths (6). The work has also included the demolition of Great Salterns Quay and restoration of the natural mudflat habitat (2,4).
The fully completed scheme will significantly reduce the risk of coastal flooding to Milton Common and the local area over the next 100 years; it will offer protection against a 1 in 500-year flood event providing one of the highest standards of flood protection in the UK outside of London (6).

The revitalization of two parks in Bydgoszcz - on 'Dabrowski’ and 'Liberty’ hills was planned in 2016 and successfully implemented in 2019. The project involved greenery planting, building health paths and outlook points, as well as new benches and a playground. It improved the aesthetic qualities of the parks, supported the effective management of rainwater and reduced noise from the surrounding areas [1].

The drought-tolerant garden was established by Portsmouth Water at its Head Office entrance in 2007. The plants in the garden, all of which require little or no watering, were chosen to be visually stimulating whilst contributing colour, scent and variation in leaf texture and shape (1). This garden has been designed to be drought-tolerant, easily maintained and can take some wear and tear. The planting reflects the changing seasons with something of interest all year. None of the plants is difficult to grow and is easily obtainable (2).

Intercultural Garden Nuremberg Langwasser e.V. is a community garden project aimed at sustainable urban development and tolerance between different social and cultural groups. People of different origins work together on their own plots (about 25 m² each), without a fences between neighbouring plots and consciously in interaction through horticulture and other activities. All the grounds are used as vegetable and flower gardens. Environmentally friendly production is desired and promoted (1). Other opportunities offered in the garden are intercultural activities and self-designed educational work. (10) The association actively promotes integration through social activities, which, as stated by the association “can include things like providing German lessons, organizing small festivals and even settling of a dispute happened once”.
