Across a large swath of northern Australia the climate is seasonally tropical. The climate is dominated by the annual Australian monsoon system, which generates heavy rainfalls from October to April and searing droughts from May to September. These strongly seasonal climatic conditions should allow for the formation of annual growth rings in at least a portion of the tree flora. We have been exploring the dendrochronological potential of several dozen tree species in the Northern Territory, including Eucalyptus species, Callitris intratropica, and ironwood (Erythrophleum chlorostachys).
