Along the ridge at the southern end of the reserve the woodland is noticeably more open than in other areas. This may be due to past fire regimes or possibly due to a difference in geology as it is the only locality where the rock is harder and high in quartz. Whatever the reason, species diversity and total biomass here appears to be lower. This gives the forest a more open feel.

White mahogany (Eucalyptus portuensis) trees often develop good hollows that are used by birds, and possums as nesting hollows. An occasionally old white mahogany trees develop hollows at their trunk base or exposed roots as can be seen in the picture below. We plan to set up a motion camera at the base of this tree to see what actually lives in there.

One species of small tree that stands out in this environment is the cocky apple (Planchonia careya).  In comparison to the surrounding vegetation, it’s leaves are a vibrant green and it bares large fluffy pink flowers during the end of the dry season.

Other trees in this ecosystem include sheoaks, geebung (Persoonia falcata), and bushmans clothes pegs (Grevillea glauca)
