Hi Konstantinos, yes it's good to get diversity in oak genetics. Me and a botanist friend are busy with assisted forest migration. We've had it so hot in France and it's been so dry and not a drop of rain in sight, we fear we're moving in the wrong direction way too fast. Nature can't keep up. The natural speed at which trees migrate is way slower than it gets warmer. So we fear we might have reached a new plateau.
The government wants to help the farmers by giving permission for mega bassins, giant outdoor swimming pools that evaporate and need chemicals in it. They suck up the ground water to fill them to feed their monoculture crops. Creeks and sources dry up and forests struggle to rech the ground water, but that's no problem, as long as industrial agriculture keeps paying tax and keeping workers busy the state doesn't care about unliveable situations for citizens. Complain, complain etc.
So instead of waiting for disaster to strike we are looking into helping nature building a diverse population of oak trees better equiped to deal with drought and heat tham our local oaks. This year they are in my region ok, although many acorns are empty, but in other regions they start to yellow up.
My friend says this.
Oaks are magical because they love to hybridize; you should plant them all—*ilex*, *suber*, *x turneri* (*ilex* x *robur*), *x hispanica* (*suber* x *robur*)... *faginea*, *rotundifolia*, *macrolepis*...—and let nature take its course over subsequent generations, allowing local oaks to incorporate new genes and create the species of the future. Simply bring a multitude of species together; since they no longer have time to migrate fast enough, adaptation will occur down the line. That is exactly what happened in Mexico during the last ice age: northern species moved south, southern species moved north, and everything hybridized. Now, there are over 200 oak species in the country, plus another 160 that recolonized the north—a major biodiversity hotspot teeming with new hybrids that are still being discovered, some of which have stabilized into distinct new species! Landrace oaks!
Do you agree with that, being an oak specialist?
