Nancy's Charter for Trees

Maintenance and management of urban nature, Strategy, plan or policy development, Improved governance of green or blue areas

"The new version of the Charter will make it possible to engage all the actors of urban policy to increase the protection of trees, to be vital to biodiversity and to the quality of the living environment. This Charter is in total coherence with the reference framework of "Nancy, a sustainable European city" and in continuity with the document drawn up by the Urban Community on Vegetal in the Grand Nancy." "Our ambition is to build the world of tomorrow where the plant element has roots anchored in our territory" "New knowledge has enabled us to learn more about the plant world and its interactions with the urban environment. New legal, urban, ecological and social issues have emerged. The old charter now requires improvements in the face of certain evolutions. It was decided to renew it. This new document is in line with the previous one and faces the new issues of the trees in the city." (Ref. 1, p 9)"The charter had made recommendations to improve the tree heritage" (Ref 1). -"Maximizing diversity means improving the multiplicity of services that the tree provides, both aesthetic and practical. Moreover, biodiversity is also an effective response to many plant protection and climate change issues" (Ref. 1, page 20).

"Nancy will further enrich its tree biodiversity, which is an essential element of a sustainable, reasoned and responsible development policy. The legal protection of the tree will be accentuated. In order to mobilize all citizens and involve them in the preservation of the tree heritage and its extension, the consultation process will be strengthened." "To improve tree management in the city, Nancy will develop new research partnerships with leading scientists on urban ecology." (Ref. 1, page 9) The management of the alignment trees is carried out by the Parks, Greens and Nature departments of "Grand Nancy Metrepole", ie approximately 6300 trees. While the parks, forests and landscape plantations in the city are maintained by the City of Nancy."(Ref. 2) Maximizing tree species as adaptation toward climate change: "Maximizing diversity means improving the multiplicity of services that the tree provides, both aesthetic and practical. Biodiversity is also an effective response to many plant protection and climate change issues" (Ref. 1, page 20). -no chemicals: -"Since 2005, the City of Nancy has adopted a "zero phyto"(zero-pesticides) approach in day-to-day management. The control of pests is achieved by the release of natural predators. Water spraying causes lime mites and aphids to fall. It is also possible to control populations using pheromone traps. The simple differentiated management of the natural space is sometimes sufficient: the high grass is the habitat of predators."

"The water vapor given off by a tree makes it possible to significantly lower the air temperature in cities" (Ref. 2). "Trees can stock an important quantity of carbon dioxide, reducing the greenhouse gas effect" (Ref. 1, page 43). "It fixes polluting particles in the air in addition to being a source of humidification. The water vapor given off by a tree makes it possible to significantly lower the air temperature in cities" (Ref. 2). The roots of trees maintain soil that is sensitive to erosion" (Ref.1, page 43). “impermeable urban soils can result in considerable runoff. During large storm events water treatment systems cannot handle the quantity... Trees act like retention basins and are an efficient water management measure" (Ref. 1, page 43). “In total, more than 28 green spaces were created in 20 years, more than 42 hectares." "More than 14,000 trees have been planted in 15 years." "The large projects of the last five years have led to an increase of the tree heritage of more than 40%." (Ref. 1, page 10). The territory of Nancy, with only 1500 hectares for nearly 110 000 inhabitants, has a proportion of natural areas that is very large: 320 hectares, private and public. (Ref. 1, page 5) “Maximizing diversity means improving the multiplicity of services that the tree provides, both aesthetic and practical. Moreover, biodiversity is also an effective response to many plant protection and climate change issues" (Ref. 1, page 20).
