> 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.
I thought pine trees were particularly acidic or their pine needles are, which is why the floor of pine forests is not very diverse, just large blankets of dead needles.
The second part is right though, these are important but very long term efforts worldwide which is why we need to start doing something now. A few percent difference could still be the difference between a fire and not a fire or between new wildlife moving there or not.
Burning the pine is how you end with a soil composed of 90% sand. Respecting the slow building of fertile soil is basic. There are several decicuous trees able to grow in very acid soils. Not so much in acid, plus sandy, plus salty.
A fact that is not being noticed is that pine trees forests evolve naturally to substitute the pines with a bigger mix of species so if you plant a pine monoculture you need to manage it to keep the monoculture. This forest evolution happens for free by natural means unless:
Sheep enter the forest or...
Weather is very cold or very hot or...
Soil is really poor, because wildfires.
Keep controlled this variables for a generation and the flammable monoculture problem will fix itself. All forests evolve to be eventually less flammable, but they need time to do this.
