Bushcare Notes: Bribie Island Pine

By Peter Wear (Bushcare)

Bribie Island Pine (Callitris columellaris) is one of the most common native trees on our Bushcare blocks. It is found throughout the island, particularly on the Emerald Fringe, where its bright green colour may have inspired the name of this heritage listed zone around the island’s perimeter. It can grow up to twenty-five metres, with dark, fissured bark that contrasts with the smoother, paler surface of nearby eucalypts.

Its termite-resistant timber has been used in building construction since colonial times. In late winter and spring, brown pollen can be seen covering the trees, awaiting dispersal by puffs of wind. Another feature of the Bribie Island Pine is that it is allelopathic; that is, it produces toxins that inhibit the growth of competing plants. Scientists are exploring the potential of such naturally occurring agents for weed control.

We notice in our Bushcare zones that where there are clusters of Bribie Island Pines, few other species grow, including weeds.
