Habitat and biodiversity conservation

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).

"The Lez is a small Mediterranean river 28.5 km long, born from a karstic exurgence whose supply zone extends north of the source, over more than 150 km2. The “Le Lez” site was proposed in February 2001 because of the presence of several species and natural habitats protected at European level. The designated part concerns the upstream course of the Lez river, its riparian forest and associated agricultural environments. Covering an area of ​​144 hectares, the area stretches over 14 km from the Lez sources in Saint-Clément-de-Rivière to the Concorde bridge, in the town of Montpellier" (Ref. 4). Strong economic and demographic development near Le Lez implies urban pressure on peripheral sectors, particularly north of Montpellier where many residential areas are developing. The river became protected thanks to the "Natura 2000 European network" which aims to reconcile human activities and the conservation of biodiversity on the basis of the main principles of sustainable development (Ref. 4).

The agriparc of the Mas Nouguier is an agricultural reserve entirely maintained by the city of Montpellier. Conducted in organic agriculture, the estate contributes to the preservation of the identity of the territory and to the valorization of the living environment. Accessible to all, it offers a beautiful walk in the middle of the vineyards. Apiaries are used to develop educational workshops and to collect honey with school children. Olive trees, centennial pines and a large meadow come to embellish this little bit of countryside in town (Ref. 1).

The Street Office (Gatukontoret) and VA Syd rebuilt Fjärilsparken (The butterfly park) in Bunkeflostrand (Malmö). For the shallow stream that runs through the park the slopes of the dikes have been made flat, meadow vegetation and wetland-plants planted in the wetlands. An area east of the park was built with houses and stormwater was managed in new ways (ref. 1). Opening the park up to the sea, flower beds were planted for richer plant and wildlife, butterfly-attracting plants were planted, lighting for safety was installed and areas with benches and bridges were created (ref. 1).

"Micro-flowering are participative urban gardening projects that allow the vegetation of streets by small plantations of annuals and perennials, vegetable and ornamental, in the municipal public space. Generally, it is a matter of developing a mineral surface on the municipal surface of the city by planting pockets. These are then maintained by the inhabitants who requested micro-flowering. Micro-flowering is a place of sharing and conviviality that allows the inhabitants to be actors of their neighborhood" (Ref. 1). In 2018, formalized 'greening permits' were launched. In this system, micro-flowering permits are requested by residents and "The municipal agents come to drill the concrete of the sidewalks and the City provides the plants" (Ref. 9 and 11).

Sweden's second largest population of the acutely threatened Green Spotted Toad ("Bufotes viridis") populates in the Northern harbour (Norra hamnen) in Malmö. In 2014 when inventories were carried out, it was shown that four water areas were used for reproduction. Despite a major exploitation interest, city administrations and landowners, together with the County Administrative Board (Länsstyrelsen Skåne), agreed to protect the population and to take measures to maintain its status (ref. 1, 2). A 15.5 hectare area had been protected until further notice from continued land changes and other disturbing activities, and the area had been fenced (ref. 1).

Larkhill Gardens Lake improvement is a collaborative project between the City Council, the Environment Agency and the local community. It is part of the long-term project, Liverpool Park Lakes Project, whose aim is to tackle many problems faced by shallow park lakes. Larkhill Gardens Lake (4936m2) a circular shaped, steep, vertical hard-banked lake, situated in a small estates garden in the city. Like many lakes, Larkhill Gardens Lake experienced problems linked to structural decline, lack of water, poor water quality, poor habitat quality, loss of management of the user and lack of proactive management by the City Council. The improvement of the lake included changing its structure to create a deep-water fishing area, shallow water area and wetland.
The project was funded by a partnership between Liverpool City Council and the Environment Agency (Reference 1).

"Since August 2004, the city of Montpellier has allowed residents to rent plots of garden, called "Les jardins Familiaux"(family gardens). The first plots were located in the Mosson district, but in view of the success of this operation, the city decided to open additional gardens at the Grands Grès site in the Port Marianne district, then at the Rieucoulon in the Croix- Money. The enthusiasts of green spaces can thus indulge in the pleasure of gardening in family thanks to these brackets of greenery. They grow vegetables and fruit as they please"(Ref. 1). Seventeen gardens (as of August 3, 2020) are located in different areas across the city (Ref. 6). "These gardens are urban planning tools favoring the social bond and the preservation of biodiversity and the urban landscape, for the gardeners interviewed these are essentially places of nature and well-being in the city"(Ref. 4)

The rooftop garden of Nádor 15 was implemented as part of the sustainable campus development strategy of the Central European University. It contains a community garden that is managed by the CEU community, intensive green roofs and green walls as well. The rooftop garden also collects water for it's automatic irrigation system and supports biodiversity with bat shelters, bee hotels and birdhouses. (Reference 1)
