Animal-plant interactions: applying the theory on the ground in north-east New South Wales

Abstract

Northern Rivers area of north-east NSW Questions for reserach: Positive and negative attributes of mixed weedy regrowth, and how these affect animal-plant interactions. Weeds can inhibit regeneration but can provide habitat resources, seed deposition sites, and establish corridors for animal movement. How can we manipulate weedy regrowth to trigger regeneration and maintain wildlife habitat? Herbivory of regeneration and planted trees by swamp wallabies Wallabia bicolor which has thrived in weedy matrix areas and has expanded its range to further areas - however, thye may have a positive role as well, for example through movement of mycorrhizal fungi. Genetic diversity - need to know how far certain plants are able to disperse their genetic material (pollen and seed) and whether there is effective dispersal between remnants.
