,Host specific refers to an organism that will only survive when it has a specific food source (the
host) available - term is used when referring to a bioagent that can survive only on
the target pest it is intended to suppress
Integrated Pest Management (IPM) a pest management strategy that uses various combinations of pest control
methods in a compatible manner to achieve satisfactory control and ensure
favorable economic and environmental consequences
Maintenance control (of aquatic weeds) a method for the control of aquatic plants in which control techniques are utilized in
a coordinated manner on a continuous basis in order to maintain the plant
population at the lowest feasible level
Management goal as applied to aquatic plant management, the amount and/or types of plants that will
be controlled or allowed to grow to best satisfy all water uses; often formally agreed
upon by representatives of all water use interests
Multi-use water body a water body that is used for more than one purpose such as fishing, waterskiing,
waterfowl hunting, and domestic water supply
Nitrogen a naturally occurring element in soils that is required in large amounts for plant
growth and will stimulate the growth of aquatic plants if no other factors are limiting
Phosphorous a naturally occurring element in soils that is required in small amounts for plant
growth and will stimulate the growth of aquatic plants (especially algae and floating
plants) if no other factors are limiting
Plant nutrients elements, such as P and N, that are required for plant growth
Productive water bodies those water bodies that support large amounts of plant growth as well as abundant
aquatic organisms because they are high in nutrients, especially P and N
2,4-D introduced in 1946, the first synthetic herbicide used. Extremely effective (water
hyacinth) and economical to use and was not toxic to fish, cattle, or humans
River and Harbor Act of 1899 federal legislation that authorized construction and operation of vessels and log
booms for the removal and containment of water hyacinth in navigable waters of
Florida and Louisiana
Florida Department of Natural Resources (DNR) agency designated in 1970 as Florida's lead agency in aquatic plant control;
responsibilities later transferred to FWC
Florida Fish and Wildlife Conservation Commission (FWC) Florida's lead agency for fish and wildlife management, formerly Florida Game and
Freshwater Commission
US Army Corps of Engineers (COE or USACE) the engineering branch of the US Army
,Florida's water bodies - over 7,800 lakes that are over 1 acre in surface area
- network of over 1,700 rivers and streams
- thousands of miles of canals used for drainage and/or irrigation
- thousands of miles of artificial water impoundments (e.g., recreational ponds,
permitted water retention ponds, and aquaculture production ponds)
Canals and surface water retention ponds predominantly serve for storage and movement of water to prevent flooding; provide
secondary benefits such as fishing, aesthetics (aquascaping), wildlife habitat, and
wetland mitigation
Why are most of Florida's waters naturally productive? abundant phosphate deposits in underlying soils
What is often the objective of aquatic plant management? to selectively control nonnative plants for the benefit of native plant communities
What are some of the most problematic aquatic weeds? - water hyacinth
- hydrilla
- torpedo grass
- alligatorweed
- hygrophila
What are the majority of public funds for aquatic plant control of water hyacinth and hydrilla
management spent on?
How are management goals often determined? type of water body
What is the management goal for drainage canals? minimize vegetation that will interfere with water movement
What is the management goal for a pond used only for minimize vegetation that can clog intakes of pumps
withdrawal of irrigation water?
What does maintenance control? minimizes detrimental impacts that aquatic weeds can have on water uses and on
the water body and reduces the effort needed to control the weeds
1884 introduction of water hyacinth to Florida
1899 River and Harbor Act of 1899 authorized construction and operation of vessels and
log booms for the removal and containment of water hyacinths in the waters of
Florida and Louisiana
1902 Congress authorized the extermination and removal of water hyacinths by any
mechanical, chemical, or other means
1905 Congress prohibited the use of any chemical that was injurious to cattle or man
, 1947 2,4-D successfully used to control water hyacinth
1952 FG&FWFC used public funds for limited water hyacinth management with 2,4-D
1958 Federally funded 5-year project for control and progressive eradication of water
hyacinths, alligatorweed, and other noxious aquatic plants initiated
1959 hydrilla discovered in FL
1960 FG&FWFC entered into cost-sharing contract with the Army Corps of Engineers
1965 - nationwide continuing project initiated with funding not to exceed $5.0 million
annually (increased to $12 million in 1986)
- alligatorweed flea beetles released as bioagent
1969 Aquatic Plant Trust Fund established
1970 DNR designated as lead agency in aquatic plant control under Florida Weed Control
Act of 1970
1972-1977 water hyacinth weevils and water hyacinth moth released as bioagents
1974 maintenance control defined
1979 American Assembly Conference on the Management and Control of Aquatic Weeds
in Florida held in Florida
1980 - aquatic plant control activities turned over to local government and the 5 water
management districts
- DNR given permitting authority for all these activities , except the use of
herbivorous fish
2008 - authority to direct and operate Florida's invasive plant management program
transferred from FL DEP (formerly DNR) to FWC (formerly FG&FWFC)
- responsibilities to regulate importation and transportation of aquatic plants moved
to FDACS
A lake that is used by fishermen, hunters, and water-skiers b) multi-use lake
would be best defined as what kind of lake?
a) domestic water supply
b) multi-use lake
c) hunting lake
d) fishing lake
