Essential to soil health and carbon sequestration, fallen leaves are much more than a melancholy symbol of autumn. A veritable fuel for ecosystems, they nourish the soil, harbour an abundance of biodiversity and play an active part in the carbon cycle.<\/p>

We sweep them up, blow them away, sometimes dread them... Yet beneath our feet, these decomposing leaves play an essential role: they return to the soil the nutrients needed for plant growth and contribute to the formation of humus, a reservoir of organic matter and carbon. Their slow transformation depends on the climate, the type of soil and the tree species present - hardwoods, for example, offer a more easily decomposable litter than softwoods.<\/p>

This carpet of dead leaves is also home to a discreet but abundant fauna: mites, springtails, earthworms, fungi and bacteria work together to maintain soil fertility and the stability of ecosystems. Without them, nature would lose one of its invisible driving forces.<\/p>
