Survey sites are traversed on foot and the weed species present are recorded on a handheld GPS unit. GPS data is processed using GIS software. Points are used to denote individual plants or polygons are used to display densities of weed species within a particular area. Depending on the project requirements, either all weed species are recorded within an area, or only a selected list of species of concern are recorded.
Data relating to weed species presence/absence is recorded on a handheld GPS unit including botanical name, common name. The cover or the extent and density is measured according to the scale described by DPaW in standard operating procedures.
