Trees
The beukenzuilen (beech columns) near the Radarterrein form one of the Bos's most recognisable stands. Beech is the host of Lactarius blennius, L. subdulcis, Russula fellea, and Cortinarius species — including, per the existing dossier, the NL-first Cortinarius variiformis. The gnarled beeches near Bloesempark are smooth-barked landmarks.
