Protect and enhance urban habitats

LIFE VIMINE is a project that aimed to define and apply a new type of integrated approach to the management of the territory, based on the erosion protection of the most indigenous barns and marshes in the Laguna of Venice. These unique habitats are rapidly disappearing due to natural processes and human impacts of varying nature. The project has contributed to repair and protect salt marshes borders as soon as erosion starts, build micro soil bioengineering works that are able to absorb wave energy, reduce erosion, promote sedimentation with a low effort and cost and improve coastal resilience and protection (1).

Formed by residents and local organisations, the original focus of Greening Wingrove & Arthur's Hill was to address issues of litter and flytipping in Wingrove. The informal association later became a Cooperative (Community Interest Company) (1,2). Since its formation, the organisation aims to clean and green its part of Newcastle's West End through a diverse set of activities (15). These include the development of a former bowling green to become a community bike garden and community hub; encouraging locals' action on litter, promoting greening and food growing and local stewardship (4)

The Wild West End project encompasses the goals and visions of Greening Wingrove & Arthur's Hill. The project is aiming to explore local natural heritage, with a focus on species currently at risk such as bats, birds (swifts and house martins) and hedgehogs with the inclusion of residents, schools and local communities. Besides mapping the status of these species, habitat creation is also an objective to prevent the further decline of these at risk species in the area (15, 16)

The WWF Oasis of Valle Averto extends to the edge of the Venetian lagoon and is a typical fishing valley of the Venetian lagoon, the only one closed to hunting. It is located within a Community Importance Site (SIC IT3250030). It is also a Special Protection Zone (SPP IT3250046). The area, about 200 hectares, includes ample mirrors of brackish water, canes, igrophilous forests, canals. After being purchased by WWF, plants of the planífico igrofilo forest kind were re-introduced: oak, black poplar, elm, ash and other typical species (1).

The project aims to reintroduce Patella ferruginea in the three Protected Marine Areas (AMP) (Portofino, Bergeggi and Cinque Terre), where the causes of extinction have been eliminated and an adequate level of protection is ensured (1). The project expects to achieve the following results: Biodiversity recovery and restoration of ribbed Mediterranean limpet by re-establishing a local population starting with 100 specimens; Reproduction and production of juveniles (some 6 000 larvae per year) to be introduced to the target areas for restocking; Full recovery and new population development of ribbed Mediterranean limpet in the target area; Restoration of the population translocated from Tavolara by introducing juveniles from controlled reproduction; and Strengthened territorial promotion and reinforcement of the “clean sea” message" (4).

The Jardin des Plantes represents a space rich in nature in the heart of the city and also hosts the Opera Theater of Saint-Etienne (Ref. 2). In 2015, "A thematic urban commission (with the citizens' district representatives) is set up to enhance the "Jardin des Plantes" while keeping its wild side but with a controlled vegetation." For instance, the social center proposed a fitness trail and elected representatives propose a signage of trees, the integration of design, thanks to urban furniture and ephemeral works" (Ref. 1). Citizens requested that vegetation of walls be undertaken to "avoid the flourish of unattractive tags" (Ref. 1).

O'pflanzt is! is a community garden in the inner part of Munich. It was founded in summer 2011 by Vanessa Blind. Her vision was to create an urban, socio-ecological community garden - a place of planting, sowing and harvesting, a place for meeting and learning, a piece of nature in the city, a creative wilderness. The garden is a real community garden, as there are no individual beds, and decisions are made collectively. Sustainable production is one of the main goals of the project, which is why planting is done organically without synthetic fertilizer and only wood and recycled materials are used. (Reference 2) In 2018, the area of the garden had to be returned to its owners. The leaders of the garden, however, managed to find a new plot within a year and a half. (Reference 13)

"Pending the creation of housing and new walks by 2020, the association Carton Plein and the EPA (Public Building Institution) of Saint-Etienne have created a temporary public space on the site known as "la Cartonnerie". A place for exchange and conviviality, the site hosts artistic installations, ephemeral installations and events. It is a laboratory conducive to imagining new ways of doing the city" (Ref. 1). The citizens also created shared gardens in this area called "Le Jardin Experimental"(Experimental garden) (Ref. 4).

Lisbon's Biodiversity Route is a pedestrian route of 14 km, marked according to the norms of the Portuguese Federation of Camping and Mountaineering. It connects the Forest Park of Monsanto to the Tejo river, which aims to contribute to raising the awareness of the value of the city's biodiversity (ref. 4). The position and dimension of these connected areas important in relation to the climate regulation, air quality and for the diversity of habitats that the city offers. The Biodiversity Route is a circular route, which can be done on foot or by bicycle where each species of fauna and flora that can be observed (Ref.1).

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 "Green Play City", a nature experience park on 4,500 sqm exists since 1999. Initiated and administered by the non-profit organization "Wissenschaftsladen" (short WiLa), it combines nature experience and recreation for kids and grown-ups with education about the environment and nature-based design while also serving as a place for social interactions through intercultural events (3,4). The initiative "Raus aus'm Haus" aims at expanding the educational and participatory component of the Green Play City. By closely collaborating with schools and kindergartens on options for related on-site workshops, project days or open-air classrooms will be explored and conceptualized (1).
