Reviving cobblestones to microhabitats for fauna

Construction sites are often seen as a nuisance, with the noise, dust, and debris they generate. However, did you know that they can also be an unexpected source of biodiversity? By reusing materials such as cobblestones and creating microhabitats for fauna, construction sites can help support local ecosystems and promote sustainable development. 

When you enter a construction site, it’s easy to only see waste. But when you think beyond this, these old materials are a source of inspiration. At the Coronmeuse site in Liège all existing materials, such as cobblestones, old bluestone borders, foundations, and pruning waste, will be reused, recycled, or even composted. This reduces the need to extract new materials, reduces waste, and helps save energy. It’s like the well-known three R’s “reduce, reuse, and recycle” but on a massive scale. 


Building a sustainable future, one stone at a time

And when these pre-loved resources transform into homes for small animals…it’s like a full circle moment. Cobblestones can be reused to make small walls, rock gardens, or even simple piles that provide shelter and protection for small animals such as insects, reptiles and amphibians. 

Moreover, microhabitats can be easily incorporated into urban areas, providing a green oasis in the midst of concrete and asphalt. By creating these small-scaled eco-homes, we can encourage the return of biodiversity to our cities and towns, promoting a healthier and more sustainable environment.
