Invasion of Melaleuca Quinquenervia in Southern
Florida by: Val Steinbronn
Introduced Species
• Native to Australia• Impacts fire management in S. Florida
• Changes soil topography• Invades Cladium jamaicensis marshes
Plant Facts
• Grows up to 90 feet high(20 meters)• Forms dense stands• Loose outer bark• White flowers• Seeds produced in capsules
Fire Management Concerns
• Crown fires common• Foliage contains flammable oils/resins• Increased reproduction potential post burn• Leaf/branch litter on forest canopy allows for
ground fires and more intense fires
Integrated Pest Management
• Mechanical treatments
• Herbicide application
• Biological control agents
Biological Control Agents• 1997 Oxyops vitiosa (melaleuca leaf weevil)• 2002 Boreioglycaspis melaleucae (sap-sucking
psyllid)• 2004 Fergusonina turneri (melaleuca bud gall
fly)
Herbivory Study• Herbivory by Oxyops vitiosa reduces
reproduction (Pratt et al 2005)
