This question is about looking! In this forest there are indicative herb species of acidic and open forests, one of them is European blueberry (Vaccinium myrtillus, blauwe bosbes). However, if you look really carefully, you might find other species that you can identify and link to this forest type. You might even still be able to find heather!
