Effects of garden type and distance from bush on adventive trees in domestic gardens

Gardens are both a source of plant species that invade native vegetation (bush) and places can invade. We test the hypotheses richness adventive exotic trees in suburban gardens declines with distance from bush, type garden strongly influences establishment trees. The woody front houses on randomly selected streets three Hobart suburbs were observed street, along type. Distance bush boundary was measured maps. Most taxa occurred less frequently increasing associated occurrence several taxa. had no effect Pittosporum undulatum, possibly because it is rare due to its fire sensitivity but attractive many gardeners well-dispersed by birds between gardens.
