I'm asking for a compatibility with forestry trees!

Forestry wood types are already supported. Maybe your block type config is messed up? Try resetting "Block Types / Wood Log Whitelist" to default, or just deleting the BF config file.

Hello! sorry for the late response :l
I've tryed what you said, deleting BetterFoliage.cfg but seems that it didn't solved the problem °-°

I noticed that some forestry trees like brazilwood wood (that WAILA show me as from Extra Trees) appear to have rounded logs and instead other trees like for example maple wood (where WAILA show me as from Forestry for Minecraft) appear to be squared.
I'm actually using Forestry 4.2.12 with Binnie Patcher 1.6
