Increase in protected green space areas

Forests fulfil several important climate functions, they are carbon sinks, regulate the local climate or buffer heatwaves and cloudbursts. Based on climate projections, longer dry periods are to be expected during summer months which have major implications for local humid forests. The “fit for climate change” project was initiated to develop and implement climate adaptation measures for the latter, for instance via hydrological regulation, the use and reinstatement of resilient, adapted tree species or revitalizing moors and swamps. It was administered by the regional forestry authority and the nature conservation station Münster (Ref. 1 and 2).

The Restoration of degraded wetlands in Wolfschlugen (in the administrative district of Stuttgart) was conducted within the wider regional level of sustainable urban development to enhance resilience, protect the city from flooding, support sustainable development, and safeguard biodiversity. Ditches and craters line the 700 metres long and 50 - 70 metres wide strip of landscape northeast of the development boundary behind the Wolfschlugen forest cemetery. This is formed by the Riederwiesen, which absorb water to protect the place from flooding. The wetland should protect people at least during a so-called hundred-year flood and at the same time offer animals and plants a habitat. (ref 3, 11)

With the relocation of the railways between the Hauptbahnhof and Pasing a large area became available for an infill development strategy. The redevelopment of central railway areas of Munich is in line with the city's guidelines for sustainable development (Perspective München) referred to as compact - urban - green. The initiative is aimed at implementing 7500 new flats and creating 15000 new workplaces in total, which are supported by green recreational areas. (Reference 1) The project consists of six separately planned parts, some are already partially finished. (Reference 2) This NBS discusses Birketweg, one of these parts, which is 60 hectares large.

Wigan Flashes Project is encouraging natural re-colonisation to a site of very high conservation value and an enormous asset for recreation for the local community. The Wigan Flashes are a group of eight shallow wetlands, formed originally as a result of mining subsidence, which extend south from near Wigan's town centre. Over time, the industrial landscape has evolved in to a mixture of open water, reedbed, mossland, willow carr and fenland (ref 1).

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).

"This 26-hectare park, the largest in Clermont-Ferrand, offers a privileged view of the city. Several wooded areas serve as shelters for permanent and passing wildlife. For the last two years, gardeners in the park have no longer used pesticides to maintain Montjuzet Park, the effects are already measurable on the enrichment of flora and fauna." "During the development of the Parc Montjuzet, the choice was made to keep 9 hectares without intervention. These hectares could be a source of some ecological richness. Hives have been established near this area since 2009." (Ref. 1) This park has the Refuge LPO label. (Ref 2)

The project tackles the habitat fragility of the Ligurian wetlands and the impact of a turtle species called Emys orbicularis in the Centa Piana river, the Vara and Magra rivers areas. The project focused on the restoration of the natural habitat, the eradication of invasive American species threatening the European turtle species and the assistance of local turtles reproduction and re-introduction in the wild. A large part of the project was conducted thanks to the participation of volunteers and large emphasis was given to education about environmental habitats protection. (1)

In an effort to improve the Holásecká lakes for both recreation and local natural conditions, the revitalization project has modified areas on the shores of the Holásecké lakes reconstructed culverts between the lakes, and removed the panel which fortified the Opleta and Lávka lakes (Ref. 4). The largest restoration activity includes removal of mud from the lakes (which can be repurposed due to low contamination) for the sake of ecologically restoring the area (Ref. 4). Plans also include improving recreation by installing wooden piers and developing a paved footpath with benches (Ref. 1). The ecological restoration will be important for wildlife, especially birds and amphibians (Ref. 8).

The Arcadia nursery is a new building located at the King’s Buildings Campus, Edinburgh and owned by the University of Edinburgh. The current intervention is about promoting ideas of free play and having elements of forest schools and natural play within the garden. As outdoor spaces associated with pre-schools is critical to the health and well being of children, this project is one of the very important initiatives in the city. It mixes indoor and outdoor play areas, and children can move between the eco-friendly building and a specially landscaped garden. The playrooms lead to a garden which enables 'nature' to be in close reach for the children. (ref 1, 4)

The Côtes site is a natural space of 1300 hectares surrounded by the urban area of the Clermont-Ferrand area, between the cities of Clermont-Ferrand, Durtol, Nohanent, Blanzat and Cébazat. (Ref. 1). Its fragile biodiversity has required special attention from the city with several actions being taken to protect it from growing urbanization. Part of the site is a Natura 2000 area and the Clermont part of the overall site is designated a sensitive natural environment (ENS). A management plan was developed for the ENS and put in place for the years 2019-2024 (Ref. 12).
