Species-focused

This intervention is about the restoration of the riverbanks of the Janon River along a street in the Terrenoire District of Saint Etienne. This area was abandoned for more than 10 years, without maintenance and cleaning. Therefore, this intervention was mandatory for clean up to avoid flood as well as bringing back vegetation and offering some quality walking areas for citizens (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).

The Brackwede open-air pools have been a significant landmark of the city of Bielefeld and part of locals' life since 1926. After several renovations since its opening, in 2005, the maintaining company of the Brackwede open-air pools proposed to convert the pools into natural-water bodies through the application of natural water filtration systems. The pools are supplied from the natural underground stream of Ems-Lutter whose spring water is physically and biologically purified by natural mineral soil filter and water plants. Chlorine is prohibited in this pool - the nature itself ensures water quality (1). Since 2009, the Natural pool of Brackwede offers natural facilities for swimming and other water-related activities besides cultural, sport and recreational opportunities for all (1).

"The main idea of the project is to join the two parks at the end of the intervention (Pedion Areos and Lofos Likavitou) with a green mass that will flow all along the intervention, bringing back the greenery to an area that used to be a green zone in the outside of the old Athens walls.That green corridor is formed by: (1) the existing trees preserved; (2) the new trees added; (3) a continuous floor all along the project with a pattern that is an abstraction from olive tree branches; (4) The artificial activity/bioclimatic trees they create" (Ref 1).

The Community Supported Agriculture initiative in Bonn (SoLaWi Bonn) is an economically motivated arrangement between consumers, farm businesses and certified gardeners to improve the urban provision of local, organic food. Together they develop a concept for collaboration where the consumer group commits to pay an annual fee to cover all of the farmer's expenses for production (according to individual financial capabilities) and to work placements at the farm per year. In exchange, the customer members of the initiative receive a variety of fresh, seasonal, locally produced vegetables. The farmers profit from financial security and economic stability and the ability to apply environmental friendly agriculture practices without the pressure of the market economy (1,4).

The lagoon has a great local significance for its biodiversity with the presence of certain species of rare birds regularly stationed in this area. Much of the biotope was degraded in the last decade by systematic embankments, constructions, as well as the inconvenience caused by various man-made pressures. A project was developed to reconstruct the area within the framework of a collaboration of the Institute of Marine Biological Resources, Inland Waters of HCMR, and Hellenic Ornology Company. The project offers directions for completing a protected region and proposes specific projects and actions of scientific monitoring, ecological rehabilitation, regeneration, and promotion. (Ref 3)

A significant expansion of the summer water level in the biggest local natural river, Giber River, was carried out in Aarhus. The increase in water flow in Giber River was achieved by a range of different measures, such as pumping purified wastewater into the river and building a string of rainwater collection ponds that will be allowed to slowly drain into the river. (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).

The botanical garden of Athens was reconstructed in 2004 to protect and maintain the biodiversity of the area. Covering a land of 1,860 sq.m., this Botanical Garden hosts over 2,500 different kinds of plants from all over the world and a rich variety of flora. All the plants and trees are protected in the park. The community also sends seeds all over the country to spread and maintain biodiversity throughout the region and hold agroecological events to increase the concern and educate the locals (Ref 1,3). The park also has a lake and a library inside it. (Ref 2)
