The spatial distribution of non-native plant invaders in a pine-eucalypt landscape mosaic in south-eastern Australia

Abstract

Factors influencing the spatial distribution of two major species of non-native plants, blackberry (Rubus fruticosus) and radiata pine (Pinus radiata) wildlings in a fragmented forest landscape in south-eastern Australia were quantified. A total of 1067 plots within three broad groups of sites was surveyed for these two non-native plant species. The sites were in large continuous areas of native eucalypt forest, an extensive plantation of P. radiata, and sites in patches of remnant eucalypt forest embedded within the pine plantation. In the case of the 507 plots located within patches of remnant eucalypt forest, an array of variables (e.g. distance to surrounding pine plantation, and florist..
