Increased spread of native/heirloom/open-pollinated seed

"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)

Warwickshire Wildlife Trust has completed an urban river restoration on the Guphill Brook that aims to restore the brook's natural features and enhance the surrounding habitat. "The project [is expected to] bring multiple benefits to diminishing wildlife and deprived local communities but also importantly to flood risk reduction, which is becoming ever more important with the increased negative effects of climate change." (Ref. 1)

Skainos is a community regeneration project developed by the Methodist Church in Ireland’s East Belfast Mission. The Skainos Project has created the Vertical Gardens where around 6,500 plants make up the vertical panels, with a height of 12.5 m. The panels are designed to change colour with the seasons and will attract wildlife. The plants condition the air, remove pollutants, and provide seasonal colour and vegetation. A variety of roof gardens harbour natural flora and fauna. Green Roof technology is used to help with water retention. (Ref 2, Ref 6, Ref 7)

The Forest of Belfast is an imaginative label for urban tree initiative launched in the 1990s with the aim of conserving and managing existing trees, increasing the planting of suitable trees, particularly in places of public access like parks, and in promoting an interest in and an appreciation of trees and forestry(Ref 3). The project was officially launched in June 1992 (Ref 1). It is active throughout the urban area of Greater Belfast, including Belfast City. It brings together partners from the statutory sector, voluntary groups, businesses, and individual residents who become volunteer Tree Wardens. It shows how urban forestry can forge partnerships between central and local government, environmental organizations and city dwellers. (Ref 1). Forest of Belfast initiative was wound up towards the end of 2010 (Ref 6).

The Paul Verlaine Garden received the "EcoJardin"(Eco-Garden) label in 2014 (Ref. 2). The EcoJardin repository is intended to be a methodological tool to guide good practices for gardeners and managers of green spaces (Ref. 6)."This garden is labeled as "Tourisme et Handicap". Work has been done so that this place takes particular account of the accessibility to the people with reduced mobility and the visually impaired. The Jardin Paul Garden is a succession of environments and vegetation architectures" (Ref. 1). At the entrance of the park, there is a playground, a garden of le Petit Poucet, and further the forest of birches, vegetable garden and the garden of tall grasses (Ref. 1).

Nancy has the most community gardens in France. While these gardens are generally designed at the initiative of associations or collectives of inhabitants, in Nancy, they are part of the urban development plans.
This demonstrates a real desire from the city to bring the inhabitants closer to sustainable development while providing them with the means to create greenery in the heart of the city (Ref. 1). The Plateau-de-Haye district, where green space was recently created, allowed the emergence of many plots (Ref. 2).

The park of "Bois d'Avaize", with an area of 30 ha, is located south-east of Saint-Étienne on a hill site between 540 and 640 m altitude. A former mining site, operated from the 15th century until 1931, it was gradually reclaimed by vegetation before being converted into a municipal park in 1996 (Ref. 1). In 2016, the site was selected for the development of a project to enhance biodiversity by creating of a conservatory orchard, increasing amphibian-friendly habitats (with creation of ponds), and improving the connection of the park with the Pilat massif (a mountainous area) (Ref. 1). It is classified with the label "Natura 2000" for the conservation of natural environments for the richness of its fauna and flora (Ref. 1). Work was undertaken between 2017-2018 with management and monitoring set to occur from 2018-2050 (Ref. 1).

The Agenda working group called "Natural gardens in Wachtberg" aims at the development and promotion of nature-based construction solutions and increased use of local wild plants since 1998. In this pursuit, it managed to acquire land (400 sqm) from the municipality of Berkum and, transform the lawn area into a near-natural garden showcasing nature-based gardening elements with the help of other environmental associations and sponsors (1,2,7). Apart from securing and enhancing local biodiversity, the garden serves as a display of possible elements and solutions of a nature-based garden for interested parties. Moreover, through information boards, workshops and a detailed brochure on implementation guidelines, the project can spark interest and empower local residents to implement such nature-based elements in their own garden (1, 3, 4,7).

Opened in 2019, the René-Dumont Park which runs adjacent to a railway is "a centerpiece of the urban composition of the Nouveau Saint-Roch neighborhood" in Montpellier. (Ref. 1 and 2). This north/south 1.2-1.3 ha vegetation corridor represents a major of the city's urban renewal plan and "allows a great articulation among existing habitats, infrastructures and a contemporary neighborhood" (Ref. 2). The large area is considered to be exceptional for dense urban centres (Ref. 2). "The Nouveau Saint-Roch district is an example of a social, generational and functional diversity" (Ref. 2).

In 2009, the city of Montpellier launched a large census project to valorize its abandoned areas. The study gives guidance on the management of abandoned areas in Montpellier, particularly in connection with environmental education and awareness objectives (Ref. 2). The strategy aims to preserve and promote the natural heritage of Montpellier; promote wastelands as reservoirs of biodiversity, tools for connecting natural spaces; protect and enhance the great green flows accompanying watercourses (biological links and privileged sites for fauna and flora); and develop a network of soft transport throughout the city based on the green network (rivers, agricultural, natural and park areas) (Ref. 4). "The spaces have been classified according to their context, their origin, their potential. This sometimes subjective typology presents a classification of the wasteland and makes it possible to take a particular look on each land. Surfaces of all shapes and sizes fall within this operational classification." Four Experimental projects include: Zenith Friche, Promenade of the Lironde, Pastourelle, Combemale" (Source: uploaded document).
