Saving trees initiatives from an association
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).
Cardiff Bay Wetlands Reserve
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).
Balne Lane Fields project
“Balne Lane Fields are an area of land close to the city centre of Wakefield. The site comprises of an area of nine hectares, which includes a former landfill site that has been restored to open green space. Part of the site is within a flood zone (Balne Beck).” “The field is popular with the local population for informal recreation. The potential to improve the variety of recreational uses, ecological value and environmental quality together with its links to both local communities and strategic greenspaces make it an important piece of green infrastructure in the City of Wakefield.” (Ref. 1)
A vegetable garden on an urban terrace
An urban garden on a private citizen's terrace in the city of Aix en Provence, has been created with the help of the organization "Pays d'Aix en Transition" working towards permaculture and urban gardening. The main objective of this urban garden is to produce vegetables and fruit for personal consumption, to install plants in a very urban environment, and use permaculture techniques. Another objective is to grow climbing plants to decorate the walls. (Ref.1 )
Urban Buzz Cardiff: A bee-friendly university
Cardiff City Council and Urban Buzz brought together local organizations, community groups supporting wildlife, to create environments to encourage more bees, butterflies, hoverflies and other insects. (ref 1). One project inspired by Urban Buzz is Pharma Bee, a project housed and run by Cardiff University’s School of Pharmacy and Pharmaceutical Sciences, that worked to create a bee-friendly campus through their PharmaBees team (ref 7). In association with Urban Buzz, a project run by BugLife, it renovated the Cardiff University’s Redwood Building by planting bee-friendly plants (ref 2), installed beehives and trained bee-keepers (ref 7). The efforts were then expanded to the Hayden Ellis building on Cardiff University's campus (ref 7).
Green Roof of St David's shopping centre
In 2013, St Davids shopping centre, which has over 200 stores and restaurants (ref 5) completed the installation of a green roof, which included bird boxes and beehives and the centre is looking to expand its green roof further. The city shopping centre has become the home of a 60,000-strong colony of bees. A second green roof was developed in 2015 in the parking garage to expand educational programs (ref 4). School children from Cardiff were involved in the planting of seedlings to create pollinator habitats for bees, butterflies and other local wildlife around the ‘Hayes’ area (ref 3). The customers and local community, with the help of this project, have been taught about the value of adopting an eco-friendly approach to public space. (ref 1)
Cardiff Castle Interpretation Centre - green roof
The Interpretation Centre at the Cardiff Castle is displaying a green roof of wildflowers. As well as changing the look of the roof, the wildflower meadow has increased the biodiversity of the area. The nectar-rich species of wildflower turf attract bees, butterflies and other pollinators. The roof had a simple irrigation system built into the substrate where the maintenance would be minimal (ref 3).
River Maritsa: Strengthening the basin
The project aims to preserve the river ecosystem and provide a suitable place for social life by the river. For the purpose, only natural materials will be used in strengthening the basin. Part of the activities include planting grass and natural vegetation in order to boost the ecosystem, including tall plants that provide shelter and a nesting place for birds. The area under work will cover 10.6 kilometres of the urban part of the river (Ref. 1).
BBC Roath Lock Studios
The project involves the BBC Drama Village - a combination of studios and stores with associated offices and technical suites. It was the requirement for all buildings to achieve a BREEAM Excellent standard (ref 1). GreenBlue Urban structural RootCell systems were used for this development to create adequate tree root volumes, to ensure optimum tree establishment and growth in a demanding coastal location (ref 2). A Living Wall has been made which has a number of functions including the provision of a new home for solitary bees, lacewings and other invertebrates. A rainwater harvesting system has been installed (ref 1). Speaking generally, the studio, stores and office amounted to over 18,000 square meters and 900 new meters of HV, gas water drainage and telecoms (ref 1). Areas of eco-design include transportation, energy efficiency, water efficiency, materials, indoor environmental quality, waste reduction and biodiversity (ref 1).
Nine Lakes Project
"The proposal is to create a leisure landscape in the countryside to the south of Wakefield, Featherstone and the South East Rural Renaissance areas. The project looks at integrating a series of existing environmental and historic attractions such as Nostell Priory Estate, Newmillerdam Country Park, Haw Park and Anglers Country Park in a landscape that is shaped by reclaimed open cast mining, and features e.g. an innovative forest planting scheme". The proposal is part of the ‘Strategic projects’ to deliver Wakefield’s vision for green infrastructure. (Ref. 1, 2)
