Finally, in the fall of 2002, Salvinia
molesta, an aquatic plant widely regarded as the worst invasive weed in the world, engulfed Central Oahu's Lake Wilson in a blanket of green.
Over a dozen invasive plant species were noted including common water hyacinth (Eichhornia crassipes), hydrilla (Hydrilla verticillata), cogon grass (Imperata cylindrica), purple loosestrife (Lythrum salicaria), Eurasian water-milfoil (Myriophyllum spicatum), and giant salvinia
molesta Mitchell Aquarium water-moss, kariba-weed Setaria pumila ssp.
The introduced water weed, salvinia
, proliferates in the oxbow lakes on the lower Kinabatangan river.
The prolific growth of a floating aquatic fern, Salvinia
rotundifolia, occurred in all tanks during this period.
The 50-year-old crewman was working on board the Dutch-registered Salvinia
docked in Cork Harbour when tragedy struck.

Solid successes have been achieved this way, as with the control of the water fern Salvinia
molesta, in Papua New Guinea's Sepik River.
Reported values of L refer to the species-average longitudinal dimension of unicellular species, the length of floating multi-cellular aquatic species (e.g., frond length of Azolla and Salvinia
), length of aerial vertical stems, maximum tree height, shell length of mollusks, standard body length of fishes, head to tip of abdomen of insects, snout to tip of tail for quadrupeds, and fully extended head-height of bipeds.
Species of the genera Pistia, Salvinia
or Eichhornia present high stocks of N or P in their tissues (Martins et al., 2003; Henry-Silva and Camargo, 2000, 2006), moreover when submitted to an environment of reduced WLF (Neiff et al., 2008; Medeiros et al., 2016).
