Land Change Analysis of Moon Point Vegetation on Fraser Island, East Coast, Queensland, Australia

Philip Le C.F. Stewart, Patrick T. Moss, Rebecca Farrell

Abstract


This study investigates vegetation thickening and encroachment at Moon Point wetlands on Fraser Island using historical aerial photographs with present day data and a land change modeller to identify the extent of thickening and encroachment of three major vegetation types, forest, Banksia and wetlands. Through quantified assessment of the aerial photographs using fine-gauged graticules, vegetation types were manually assessed and counted to identify changes in woody vegetation density. Further vegetation polygons were created of the three vegetation types for analysis through a land change modeller for change analysis to identify percentage gains or losses of vegetation types, transition potential for change and  change prediction to fifty years into the future. Both the quantified assessment and land change modeller identified vegetation thickening with percentage gains for forest and Banksia, with forests having the greatest percentage gains. Wetlands showed an overall percentage loss to forest and Banksia, which increases fifty years into the future.
