Natural enemies for invasive climbing fern. Old World climbing fern, Lygodium microphyllum, an invasive plant native to tropical regions of Africa, Australia, Asia and the Pacific, is arguably Florida’s worst weed.  The perennial fern chokes native vegetation in wetland systems in the Greater Everglades Region.  Several new biological control agents from Australia and Hong Kong are currently being studied by the ARS Australian Biological Control Laboratory for their potential to reduce populations of the fern in Florida.  ABCL staff have sent shipments of the agents to the USDA ARS Invasive Plant Research Laboratory in Fort Lauderdale, Florida, for further evaluation to determine their host specificity and impact.
