Forest processes in the presence of wild ginger (Hedychium gardnerianum)
Wild ginger (Hedychium gardnerianum) is a tall rhizomatous herb that invades forests and shrubland fragments in northern New Zealand. In order to determine the impacts of this invasive weed on forest processes, comparisons of conifer-broadleaved forest patches with different densities of ginger were made at Opononi and Whangarei in Northland. Soil properties, vegetation structure, floristics, and seed rain were recorded. Annual litter fall biomass and chemical composition were measured.
