Construction is underway on a significant ecological restoration project in Arles, France, with the first phase of renovations to the Marais de Beauchamp wetlands scheduled for completion by the end of April 2026. The project, spearheaded by the city of Arles, aims to enhance public access to the 115-hectare natural area whereas preserving its biodiversity.
The Marais de Beauchamp, situated in the Pont-de-Crau district and within the Parc Naturel Régional des Alpilles, is a former marshland that represents a diverse range of freshwater wetland ecosystems, including reedbeds, temporary ponds, and riparian forests. The site is too part of the Natura 2000 network (FR9301596 – Marais de la Vallée des Baux and marais d’Arles) and is being integrated into the perimeter of the Parc naturel des Alpilles. This restoration highlights a growing trend of leveraging technology and ecological understanding to revitalize natural spaces.
According to city officials, the project will cost just over one million euros, with approximately 300,000 euros funded by the city itself. The renovations include the development of a two-hectare arboretum designed as a “cool island” at the edge of the city, accessible by foot, bicycle, and public transportation. The site is divided into two distinct sectors on either side of the East ring road.
The eastern sector, encompassing 25 hectares of marshland, 57 hectares of pasture, and 28 hectares of reedbeds, is a designated Natura 2000 area. The western sector includes a nautical base, a derelict area known as “Jardin des Avettes,” and a reception area spanning approximately five hectares. The project’s focus on accessibility and ecological preservation reflects a broader movement toward sustainable urban development.
During the initial phase of construction, lasting until March 31, 2026, the entire site will be closed to the public. The overall project is expected to continue through March 2027. The Conservatoire d’espaces naturels de Provence-Alpes-Côte d’Azur manages the site, which is owned by the city of Arles. Visitors are currently encouraged to stay on marked trails, keep dogs leashed, and refrain from removing any plants, animals, or minerals from the area. More information about the Marais de Beauchamp can be found on the Provence-Alpes-Côte d’Azur tourism website, at the CEN Paca website, and in La Provence.
The project aims to “promote public access” and create “a place for discovering nature, respectful of the remarkable biodiversity of the site.”
