Habitat and biodiversity conservation

Bee-friendly Nottingham is a campaign run by Nottingham City Council to make Nottingham a more pollinator-friendly city, promote pollinator-friendly gardening at council events and to protect bee populations by planting pollinator-friendly plants via planting schemes (Ref. 1). It aims to make some lasting changes to the way people manage open spaces in order to help wild and domestic bees and provide more flowers for foraging and more habitat for nest sites (ref. 1).

The Development of the Garden of the Schloessel project is part of the Natural Urban Park project undertaken by the City Council in consultation with the Strasbourg Urban Community (Ref. 3). The project aims to reduce the carbon footprint of the area by installing and redeveloping green spaces in the garden as well as providing the site with stormwater management infiltration (Ref. 1).

The project of the Park of Malaga was to rehabilitate the lateral spaces of the Paseo del Parque, the organization of the environment, the recovery of the flora and structure of the Park, as well to construct a solution for problems of mobility. (Ref. 1). Recovery of Vegetation of the park, its original layout, and its scientific character of garden Botanical and species acclimatization were central aims of the project (Ref 1).

Wildlife in the City is a project led by Nottinghamshire Wildlife Trust, with Nottingham City Council, to promote, protect and celebrate the nature reserves, wildlife sites and green spaces across Nottingham City (ref. 2). Wildlife in the City is a project run by Nottinghamshire Wildlife Trust was originally designed to raise awareness of the value of urban wildlife and to inspire people to get involved with caring for wildlife sites on their doorstep. The project aimed to engage people in their local green spaces and wildlife. Wildlife in the City ran lots of activities and events, volunteering opportunities, training opportunities and more (ref. 1). It began as a three-year project funded by Natural England through Access to Nature, as part of the Big Lottery Fund's Changing Spaces programme. The project worked with local people to undertake vital habitat creation and management works throughout the city. It particularly worked in areas of Nottingham with previously little wildlife activity from the partners. These areas were Bestwood, Bulwell, Aspley/Broxtowe estate, Clifton, The Meadows, and Sneinton (ref. 6). After the funding for the project has ended, its objectives and the partnership between the City Council and Nottinghamshire Wildlife Trust remained and the Trust continues managing many of the Council's wildlife sites and using local volunteers to help out with essential tasks such as scrub management, gardening, litter picks and floral surveys (ref 2).

The project of Nature Oasis Auwiesen is creating new habitats for animals and plants in Stuttgart. The project is one of a total of six “Neckar pearls” that are to be completed by 2022 as part of the Neckar Landscape Park master plan in Stuttgart. In the project with a predominantly ecological focus, grassland in the Neckaraue near the Aubrücke is to be transformed into a near‐natural, ecologically valuable wetland biotope. In the course of straightening the Neckar, the wet and floodplain biotopes that were typical and widespread in the floodplains have been lost. The aim of the project is to restore these habitats for animals and plants, which have become very rare today. A network of marshes, water surfaces, islands, and bushes is to be created in the district of Hofen. On an area previously used as grassland, new habitats will be created for rare animals and plants, which are dependent on water areas. Initially, the planned implementation time was 2016-2022, but now it has been delayed and is expected to start by the end of 2021. (2, 7).

The project called “The Apiary of Kraków” includes several interrelated initiatives to establish beehives on the rooftops of various institutions in Cracow. The aim is to provide habitat for bees, and protect biodiversity, support urban pollination, increase social awareness on the topic. Urban honey is of better quality than honey produced in rural areas where pesticides are more common. The local administration-led initiative aims to promote Cracow as a pro-ecological city which soon will be selling its honey [1,2,3,4].

The City of Milan intends to carry out a functional intervention in the valley of Ticinello for the strengthening of the environmental matrix and of the structural characteristics aimed at improving the ecological connection. The project, which aims to contribute to the valorisation, strengthening and conservation of the natural heritage, as well as expand local biodiversity, through the realization of terrestrial and aquatic ecosystems, is necessary for the realization, development and enhancement of large-scale ecological corridors already identified by the instruments of territorial planning (1).

INCREDIBLE EDIBLE (or "Incroyables Comestibles" in French) is an experiment of social innovation: the volunteers of the movement cultivate small vegetable gardens scattered in the cities and the countryside and make their products available free of charge (Ref. 1). This, the first intervention, took place in front of the "Epicerie du Coing" where volunteers planted several vegetables, flowers and plants (Ref. 2).

After more than one 100 trees were slaughtered in a few months upon order of the city in 2016, the association "Défenses des Arbres en Pays d'Aix" was created by multiple NGOs with the purpose of saving the plant heritage of Aix-en-Provence. Their main goal was to encourage the city's council to establish a "Charter for trees" dedicated to the city of Aix en Provence (Ref. 1). The work of the association was useful as the city decided to engage in a new charter, and prepare a new planting season with 64 trees (in 2016) (Ref. 4). The Charter was developed in 2017 (Ref. 6) and an environmental management plan for activities was developed in 2018 (Ref. 7).

The reserve is a biodiversity hot-spot within Cardiff Bay. The reedbed and other aquatic plants, are very productive vegetation and a habitat for birds. Prior to the construction of the Cardiff Bay Barrage, it was made up of mudflats and salt marsh. (Ref 1) The site was chosen by Cardiff Harbour Authority to create a new environment and compensate in part for the loss of the mudflats which were submerged after completion of the Cardiff Bay Barrage. Floating timber structures serve as breeding areas for birds, an underwater bund prevents wave erosion, and a boom keeps out waterborne debris (Ref 5).
