Differences in the Stand Structure of Eucalyptus tetrodonta Forests Between Elcho Island and Gunn-Point, Northern Australia

Abstract

Eucalyptus tetrodonta dominated open forests occur across the northern coast of the Northern Territory. They typically have a well developed grass understorey, scattered saplings, numerous woody sprouts (ramets) and a conspicuous absence of seedlings (genets). We compared a typical E. tetrodonta stand on Gunn Point with an atypical stand on Elcho Island; the forest on Elcho Island had less grass cover, greater canopy and litter cover, a deeper organic layer and higher densities of seedlings, woody sprouts and saplings than on Gunn Point. Gunn Point had a greater number of large E. tetrodonta trees that were more widely spaced than trees on Elcho Island. The cause of these differences remains unclear.
