CREXECO

Crexeco is an engineering office specialised in expertise/consulting on natural environment (habitats, fauna and flora).

Crexeco is an engineering office specialized in expertise/consulting on natural environment (habitats, fauna and flora). Between scientific research and ecological engineering, we offer independent expertise based on both scientific and naturalist approach of ecology.

Our mission deals with expertise and research on natural environments, and concerns various fields like regulatory studies, applied research and teaching.

From preliminary studies to ecological monitoring of infrastructures and wildlife inventories, our office will support any project leader in successive steps of the project.

We also develop applied research studies allowing to answer to crucial questions posed to project leaders and public authorities.

Finally we promote the diffusion of knowledge by teaching on ecology and wildlife conservation, and reading specialized literature.

Crexeco is composed by 9 ecologists : Laurent Demongin (codirector, ornithologist for more than 30 years), Hervé Lelièvre (codirector, phD in ecology and specialist of fauna), Anthony Robert (Master Integrated Management of Biodiversity and Territories, specialist herpetofauna and entomofauna), Mélanie Sillon-Hugon (Professional Master in Ecology, botanist), Nicolas Conduché (Professional license sustainable management of agricultural resources, botanist), Natasha Leclerc (Bioengineer in Forest and Natural Space Management, Ornithologist), Benjamin Leroy (Master in Engineering, chiropterologist), Mélanie Blanc(Master in Ecology and Biodiversity Management, chiropterologist), Maud Poisbleau (PhD in ecology, data analysis and writing).

In addition, we currently work with an important framework of specialized partners : botanists, zoologists, GIS engineers, scientific researchers…).
