Many invasive alien species have documented negative cross-cutting impacts, indicated by multiple colours in the examples: 
16 per cent of invasive alien species have a negative impact on both nature and nature's contributions to people; 7 per cent on both 
nature and good quality of life; and 5 per cent on nature, nature's contributions to people and good quality of life {4.2}. The scientific 
names of the example species are Lantana camara (lantana); Lates niloticus (Nile perch); Dreissena polymorpha (zebra mussel); Ciona 
intestinalis (sea vase); Lissachatina fulica (giant African land snail); Culex quinquefasciatus (southern house mosquito); Mnemiopsis 
leidyi (sea walnut); Pontederia crassipes (water hyacinth); Prosopis juliflora (mesquite); Solenopsis invicta (red imported fire ant); Vulpes 
vulpes (red fox); and Batrachochytrium dendrobatidis (chytrid fungus).
