NAV Allocasuarina verticillata forest: closed forest facies

Community Description:

Allocasuarina verticillata forest varies from pure stands with 100 % litter layer or with little else but leaf litter beneath the trees, to stands in which umbrageous trees are interspersed in a species-rich sward dominated by tussock grasses. These forests occupy very dry sites and some have emergent eucalypts or Callitris rhomboidea. This benchmark is one of 2 benchmarks available to assess the condition of NAV.
