From Le Monde:

> Some efforts have begun to diversify the Landes forest and to maintain or promote deciduous trees, particularly along the edges of plots. The major difficulty, according to foresters, is that very few species are able to grow in this region, where the sandy soil is very poor and very acidic (it is one of the poorest soils in Europe). Foresters describe the maritime pine as a "miracle species" in this regard.

> While other species can still grow, it is much more slowly and with greater difficulty. Radically transforming this vast forest, currently 80% dominated by maritime pines, therefore seems complicated, and there is also a significant economic stake involved in timber production in the region.
