“All-terrain” ecological engineering

At Egis, the environment, eco-design and ecological engineering have taken on a central role in helping to meet today’s leading challenges: the climate emergency and the protection of biodiversity. Here is an overview of our actions and know-how...

Through its Water & Environment teams, Egis has been active in ecological engineering for several decades, whether in support of land-use planning or though involvement in environmental restoration projects. Our expertise in the study phase is based on our naturalist skills (inventories, monitoring), and our advisory and support skills (regulatory environment and ARC sequence, labelling, positive biodiversity approach). As project managers for ecological restoration projects, we work in all types of environments (rivers, wetlands, forests, urban areas) and we have the capacity to co-opt ecologists into the design teams for structures and buildings.

Egis was also awarded the Special "Wetlands" Prize (2020 Ecological Engineering Prize) with the Savoie Natural Space Conservatory for the water and agri-environmental restoration of the Chindrieux marshes in the Chautagne wetland.

Initially, our ecological engineering activity was essentially focused on rural and natural environments that bordered on major regional development projects. But in recent years, Egis has also been focusing its efforts on issues related to biodiversity in urban environments (certifications, labelling, support for developers, etc.). This offering is provided through the development of innovative solutions, including Eva-Biodiversity and LandBoost.


Eva-Biodiversité is a methodology to assess biodiversity performance, designed for newbuild property programmes.

Based on five indicators, it helps to quantify the risks and opportunities at a very early stage in projects and identify the right action levers by which to mitigate impact and help design positive biodiversity projects.

Opposite is an example of the result obtained by the Eva-Biodiversité method during the diagnosis of a real estate project.



Landboost  is a set of structures manufactured using 3D printing which are designed to house wildlife on restricted or deteriorated sites. These modules, which can be either self-standing or fixed to another structure, are designed and produced to individual specifications so as to provide the best response to the challenges of the site and target species. While a tree can take several decades to provide a suitable habitat, Landboost achieves this immediately. For its design and production, our teams work in close cooperation with Seaboost (Egis group, experts in marine environmental restoration) and XtreeE, The large-scale 3D (for the 3D printing).

Following several years of development, the first Landboost totem module was installed on the Icade Paris Orly-Rungis site in October 2020. The subsequent monitoring in the coming months and years will help measure the effectiveness of this promising invention!
