“…The hypothesis that an increase in vegetation competition will suppress the emergence of invading seedlings has been proven at Mt Barker in the case of gorse, and supports the findings of a number of other researchers. Bell (1961) and Ivens (1979) showed that vigorous pasture growth suppressed gorse establishment, and that if sheep grazing was added, gorse control was almost complete. Hartley & Phung (1979) compared gorse seedling survival amongst different grasses, and found survival was lowest in browntop and highest in perennial ryegrass (Lolium perenne), with Yorkshire fog (Holcus lanatus) having an intermediate effect.…”

The effect of varying levels of rangeland vegetation competition as modified by application of fertiliser on the establishment of introduced Scotch broom (Cytisus scoparius) and gorse (Ulex europaeus) was monitored over a five year period Two growing seasons after fertiliser addition vascular plant cover in the fertilised plots was twofold greater than in the control plots After 5 years higher levels of vascular plant cover induced a highly significant (Plt;00001) threefold reduction in emergence of gorse from 37 in the control to 12 in the fertilised treatment (Plt;00001) However higher levels of vascular plant cover had no significant (Plt;064) effect on emergence of broom which was 42 in the untreated and 39 in the fertilised treatment with high vascular plant cover Implications for gorse and broom invasion and management are discussed
