The domain of Restinclières is a public estate, owned by the “Conseil Départemental de l’Hérault”. The land is rented to two farmers, one who produces cereals, the other one vine. The owner manages the trees. Research focuses on the impact of trees on the crop production and on the sustainability and resilience of agroforestry systems.

Restinclières was the first ever silvoarable experiment in France with control treatments (monocropping, forestry) that allow a true assessment of the feasability and productivity of alley-cropping agroforestry.
I am proud of our experiment because it is a showcase of agroforestry for numerous researchers, students, farmers, advisors and reporters” “If we could establish the experiment again, we would widen the alleys and choose a better location for the forestry controls by taking into account the depth of soil and water table.”
Lydie Dufour INRAE
With deciduous walnut trees, winter crop yield is not much impacted until the ratio between the height of trees and the width of the alley reaches 0.8.
Trees protect vineyard from frost or severe heat.
Tree roots are deeper in our agroforestry fields than in forestry control.
