Nature in Seine et Marne | Sein et Marne department

Living environment of Seine-et-Marnais

Seine-et-Marne is a vast region that covers almost half the area of ​​Ile-de-France. Its forests, waterways, wetlands, and agricultural ecosystems make it the green lung of the region. The department records 1,500 species of plants and 10,000 species of animals.

  • The International Biosphere Reserve extends over the Fontainebleau Forest, part of the forests of the French Gâtinais and Gâtinais;
  • La Bassée, the largest wetland in Ile-de-France, has a national nature reserve within it;
  • The Fontainebleau mountain range has been designated an Exceptional Forest since 2013. Its 25,000 hectares of natural and historical richness have inspired painters, writers, and photographers;
  • The department has also established sensitive natural areas, one of which, the Épisy Swamp, is listed on the Green List of the International Union for Conservation of Nature;

Seine-et-Marnais living environment in numbers:

The Natura 2000 network is a European system that aims to ensure the long-term survival of particularly threatened species and habitats. The inventory of natural areas of ecological, fauna and flora, which is carried out by the state, is aimed at getting acquainted as comprehensively as possible with the magnificent natural, terrestrial and marine spaces.

It has been granted the designation “Biosphere Reserve” by UNESCO. It makes it possible to distinguish between sites that are distinguished for the conservation and sustainable use of natural resources. Today, there are approximately 400 reserves of this type spread over the five continents of the world.

In 1998, UNESCO awarded the label to the Pays de Fontainebleau, which covers 70,000 hectares. According to the National Forest Office, it is home to an impressive variety of plant and animal species, including:

  • 5800 plant species including 1350 flowering plants,
  • 450 species of algae,
  • 3000 species of mushrooms,
  • 500 lichens and many algae,
  • 6600 animal species including 57 mammals, 215 birds and 5600 insects.

Sensitive natural areas

Seine-et-Marne has a number of areas with great ecological outlets. Among them, the Natural Sensitive Zones (ENS). Some are placed under the responsibility of the department, others are under the responsibility of the municipalities.

preservation mission

The Department contributes to the preservation of its natural heritage by exercising its competence related to the national heritage. This allows her in particular to have and manage great websites. This tool can be used by municipalities who also wish to participate in the development of their territory.

public awareness

Conservation cannot be complete without raising public awareness of these ecosystems, which is done through the development of the site, making it possible to offer a path to the visitor and highlight all the assets of these sites, including historical and cultural sites.

Animations for 22 administrative sites representing the ENS, were commissioned by the administration to an associated organization called Seine-et-Marne Environnement or to local associations:

wonderful trees

A wonderful tree is a tree with exceptional properties. It could be its dimensions, age, history, or unique appearance.

In total, 132 trees and groups of trees were included in the provincial inventory of the remarkable Seine-et-Marne trees, begun in 1997.

There is for example:

  • Majestic red oak, in the forest of Fontainebleau, a rare gem in this massif. The roots of its collar, emerging from the ground, enhance the impression of strength and stability that this tree emits.
  • Black poplar located on the banks of the River Seine in Noyen-sur-Seine, in an environment very rich in plant diversity on ancient alluvial soils.

Seine-et-Marne Green and Blue Mesh

The Seine-et-Marne Green and Blue Network is a regional development tool. Its goal is to reduce the fragmentation of natural environments, a major cause of the erosion of the world’s biodiversity.

It corresponds to the connection of three elements that make up the “environmental continuity” (according to environmental law).

  • repositories of biodiversity, harboring heritage species and natural environments, i.e. rare and/or threatened,
  • Ecological corridors, spaces called normal nature, are essential to the movement of animal and plant species. linking the reservoirs of biodiversity to each other,
  • Waterways and canals that potentially serve as reservoirs or corridors.

To implement the green and blue frame, the circuit mustered several tools:

The department works with many actors to support the development of environmental sustainability in Seine-et-Marne. It also helps the municipalities to implement the Ile-de-France Regional Ecological Cohesion Scheme, which aims to maintain and restore ecological continuity.

Atlas of Biodiversity and Landscape Atlas

Dynamic Atlas of Biodiversity in Seine-et-Marne

Between 2005 and 2015, the Department piloted the dynamic atlas of biodiversity in Seine-et-Marne, implemented in partnership with the syndicate and scientific world (National Museum of Natural History, CNRS, Universities). This project made it possible to identify the areas and species at risk in Seine-et-Marne, the services provided by biodiversity and the threats to it. This work resulted in the publication of four works respectively devoted to plants, animals, natural environments, ecological continuity, and human-nature relationships.

Landscape Atlas of Seine et Marne

In 2007, the department published the Seine-et-Marne Landscape Atlas with the support of the Council for Architecture, Town Planning and the Environment (CAUE). This work has made it possible to provide the services of the Ministry, the State and the design offices with a complete tool for knowing the territory from the point of view of the landscape. Thus, 35 landscape groups have been preserved, and 79 landscape entities have been identified.
