Vegetation change in an urban grassy woodland since the early nineteenth century

Abstract

Our understanding of the history of vegetation change after the British invasion of Tasmania is limited. The Queens Domain in Hobart is an area of remnant grassy woodland that provides the opportunity to document such vegetation change and its causes using historical images and reports. Tree removal, stock grazing, and the consequent reduction in the incidence of fire appear to have resulted in a decline in tree cover after European settlement, reaching a nadir during 1861–1880. Paintings and photographs indicated a sharp increase in tree cover between 1921 and 1941, associated with the banning of stock grazing. This increase appears to have been encouraged, rather than hindered, by the increasing frequency of low-intensity fire resulting from a reduction in grazing pressure
