Fil vert aims to help green the streets in Normandy and raise awareness among citizens of the importance of being an actor of their daily life with regard to the occupation of public space. They aim to "embellish our streets, which are often devoid of vegetation, but also to train responsible citizens" (Ref. 7). "Operation "Fil Vert" was launched at Croix de Pierre (District) in Rouen in September 2013 to beautify and revitalize the district by mobilizing residents and tradespeople. It aims of installing planters in front of the inhabitants and the merchants (subject to obtaining the agreement of the owners in case of hiring), along the pavements, provided that it makes at least 1.40 M width to allow strollers and wheelchairs to pass." (Ref. 3)

The orchard of the Vallon was established by the city in an area that had historically served as an orchard fifty years previous (Ref. 9). A few pear trees had survived and gave rise to the idea of ​​reconstituting it. In 2014, the city planted apple, peach, pear, cherry, apricot and other fruit trees on one and a half hectares of greenery. "At the beginning of 2015, the association Le Verger du Vallon was born. With its members, its mission is to maintain these trees with a view to sharing knowledge and educational exchanges "(Ref. 9). "Called upon by the city of Rouen for the establishment of a participatory orchard, the social center wished to promote this project among the inhabitants within the framework of the arrow projects of the CAF (social security) de la Seine Maritime entering the field of financing "to support a cooperative project of residents initiated and built with them from a common concern " (Ref. 3, page Description).

The FUTURE - a project of 100,000 trees in the Porto Metropolitan Area - is a planned and coordinated effort of various organizations and citizens to create and maintain native urban forests in this region, which needs to enrich its biodiversity, sequester carbon, improve quality of air, protect their soil and contribute to a better quality of life for regional people. The 100,000 Trees Project for the Porto Metropolitan Area” intends to restore 100 hectares of urban forest with native trees. (1, 2)

The Chartreuse Park has been chosen as a pilot site for the EU-funded VALUE project, enabling the City of Liège to finance and pilot a participatory requalification process for the Chartreuse Park. Since the acquisition of the site (about 20 hectares of park and green spaces), the City has taken several steps to recognize the historical and environmental potentialities of the Park and to integrate its values in the operations for the urban development of this old military site (the Fort de la Chartreuse). As a result of broad consultation with citizens, between 2012 and 2014, three circular walkways were created in the park connected to each other, enabling greater access to the park (Ref. 1).

A botanical garden in a forest was created owing to the cooperation of Gdansk Forest District with the city of Gdynia and the University of Gdansk. It consists of 27 thematic collections, covering ca. 50 ha, and adjacent forest phytocoenoses. The garden is specialized in showcasing trees, shrubs and herbaceous plants of the nemoral and boreal zone, particularly species indigenous for the Pomorze Gdanskie region. The garden protects a collection of species endangered and rare in the region and protected by law, as well as an orchard of old forms of fruit trees and shrubs [1,3].
The initial works have been completed, but greenery planting and further investments in the garden are ongoing. The botanical garden is a long-term undertaking and many plants were planted long before the construction began and the garden will "grow" up to 20 years [5].

The Strasbourg Grandeur Nature Plan is engineered by Strasbourg Metropole and is focused on optimising the actions and resources and resources of local authorities in the maintenance of local biodiversity and improving the living environment (Ref. 7). It combines with local associations and citizens through organising interfaces (e.g. workshops, online tools) that allow relevant local authorities to engage with local projects and make interventions on the basis of proposals made by the community. The project aims at improving the maintenance and development of green spaces and biodiversity due to the environmental issues surrounding urban sprawls (Ref. 4).

The "Ciobarciu wetland" project resulted in the creation of a wetland area of ​​about 224 hectares near the city of Iasi (30 Km distance). The area of ​​nature thus became in spring and autumn a significant resting place for migratory birds, and the specific types of natural vegetation are growing again, constituting a natural habitat for the locales specific to these places. The project was developed by the National Administration of the Romanian Waters alongside the Dutch Government in order to restore the area and to include it in the ecosystem of the place (1)

With spaces for biodiversity being continuously threatened by urban development, the environmental association Ökolöwe Leipzig initiated a biodiversity-enhancing project during the 100th Catholic Day event in Leipzig in May 2016. Consisting of green interventions at four schoolyards all over Leipzig involving the active collaboration of students who are also expected to maintain the interventions into the future and 100 mobile high beds at the central city square for public display, the project objective was to demonstrate how to foster biodiversity even in limited urban spaces while also to raise awareness (1, 3).

"The Conservatoire des Restanques is dedicated to preserving biodiversity (conservation orchard, forgotten vegetable garden, Mediterranean garden with the typical plant species of low limestone Provence) and to be a showcase of the current considerations of Sustainable Development (energy, waste management, water resources management, etc.). The development of the site and the different elements of the landscape make it possible to develop educational programs on the themes of flora diversity, wildlife, heritage conservation, food, consumption and health, eco-construction and energy management" (Ref. 3).

The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).
