         General Impact

    Asparagus densiflorus has the potential to be similar to climbing asparagus in its ability to smother forest understory to a height of 2.5 - 5 m; this species can also smother ground cover and prevent regeneration of canopy species (Bay of Plenty Regional Council, undated).



         Location Specific Impacts:
    Palm Beach County (United States (USA)) English 
    Reduction in native biodiversity: Asparagus densiflorus is found in large colonies on several scrub sites in Palm Beach County, displacing native ground cover and understory shrubs (University of Florida, 2002).
    “Has escaped as well into tropical hammocks in Palm Beach County, overtopping young native plants such as wild coffee, Psychotria nervosa (A. Zahorcak, Florida Department of Environmental Protection, 1998 personal communication)” (University of Florida, 2002).
