2 Annual Report of Activities Conducted under the Cooperative Aquatic Plant Control Program in Florida Public s for Fiscal Year This report was prepared in accordance with (7), Florida Statutes, to provide an annual summary of plants treated and funding necessary to manage aquatic plants in public waters. The Cooperative Aquatic Plant Control Program administered by the Florida Fish and Wildlife Conservation Commission (FWC) in Florida s public waters involves complex operational and financial interactions between state, federal and local governments as well as private sector companies. FWC s aquatic plant management program mission is to reduce negative impacts from invasive nonindigenous plants like water hyacinth, water lettuce and hydrilla to conserve the multiple uses and functions of public lakes and rivers. Invasive plants infest 96% of Florida s 451 public waters inventoried in 2013 that comprise 1.26 million acres of fresh water. Once established, eradicating invasive plants is difficult or impossible and very expensive; therefore, continuous maintenance is critical to keep invasive plants at low levels to sustain attributes like navigation, flood control and recreation while conserving native plant habitat for fish and wildlife on sovereignty state lands. A detailed description of the uses of Florida waters, how aquatic plants may impair these uses, aquatic plant control options, management plan development, and research and outreach efforts is presented in the following website designed and maintained in a collaborative effort between FWC and the University of Florida, Center for Aquatic and Invasive Plants: A summary of plant control in sovereignty public waters and associated expenditures contracted or monitored by the FWC during Fiscal Year is presented in the following pages. Management statistics are summarized in Tables 1-4 and presented graphically in Figures 1-4. FWC s highest management priorities (established in rule under section 68F F.A.C.) are the control of floating plants (water hyacinth and water lettuce) and hydrilla. Other plants listed in the tables include both native and nonindigenous plants that may impair the uses of Florida public waters. Table 1 presents the amount of control and associated funding for each plant type within the boundaries of the five water management districts to provide some geographical perspective on where plants are controlled in Florida. Table 2 breaks down aquatic plant management expenditures by federal and state funds. Twelve aquatic plant species found in Florida are considered to be invasive in that they are capable of causing environmental or economic harm if not managed on a routine basis. Some are widespread like floating plants or hydrilla and are under continuous maintenance. Others are present in only a few locations and are under eradication programs to prevent them from becoming established in Florida waters. Table 3 lists individual plant types found in Florida public waters summarizing acres controlled and associated control expenditures for Fiscal Year Table 4 lists management expenditures by waterbody, including assessment and monitoring costs. Figure 1 shows the ranges in size of the floating plant populations reported in Florida public lakes and rivers in Although these plants are widespread, found in 255 public waters, most populations are being suppressed to fewer than ten acres, keeping overall management costs and environmental impacts at low levels. Figure 2 shows water hyacinth cover in Florida public waters in ten-year intervals dating from 1947 through 2013 to give an historical perspective of the presence of this prolific plant species through the decades. The Maintenance Control management philosophy 1

3 was implemented for floating plants in the early 1970s - control invasive plants on a statewide coordinated, routine and consistent basis - to reduce the overall population from about 125,000 acres in 1959 to a few thousand acres at any one time for the past 35 years. Floating plants were under maintenance control in 98% of Florida s public waters during Figure 3 shows acreage ranges for the 194 hydrilla populations that were reported in public lakes and rivers in Seventy-five percent of all hydrilla populations observed in 2013 covered fewer than ten acres, and hydrilla was considered to be under maintenance control in 98% of Florida s public waters in Figure 4 compares funding for hydrilla control vs. acres of hydrilla reported in public waters from When funding is adequate, hydrilla can be suppressed at low levels. When funding is insufficient, hydrilla expands and forms underground tubers that can persist for many years, representing the potential for immediate regrowth after control, and the need for prolonged higher levels of management funding until these tuber banks are depleted. 2

4 Year in Review - Fiscal Year Invasive non-native plants were reported in 96% of Florida s 451 public lakes and rivers that comprise 1.26 million acres of fresh water. Eradicating established invasive aquatic plant populations has proven nearly impossible; therefore, routine maintenance is needed to suppress invasive plants at low levels to sustain attributes like navigation, flood control, and recreation while conserving native plant habitat. Floating water hyacinth and water lettuce, two of the world s fastest growing plants, covered as much as 125,000 acres of Florida public waters as recently as the 1960s and therefore are the FWC s highest management priorities. Floating plants were present in 255 public lakes and rivers in 2013 covering about 5,880 acres and are under maintenance control in 98% of Florida s public waters. Eighty-four percent of the floating plant populations reported in 2013 covered 10 acres or less. (Figure 1) Managers spent about $5.80 million controlling 46,757 acres of floating invasive plants in Florida public lakes and rivers during (Tables 1-3). This was about a 40% increase in funds expended and acres controlled in FY as managers coped with increased floating plant growth, a common occurrence as lakes refill after extended drought. Submersed hydrilla, imported during the 1950s as an aquarium plant, is capable of growing several inches per day filling the water column and covering the surface of water bodies that are not frequently and routinely managed. Insufficient funding allowed hydrilla to evolve into statewide water and habitat management crises by the middle 1990s infesting about 100,000 acres in 365 (80%) of Florida s public lakes and rivers. Sufficient, recurring funding and improved technology aided by FWC-funded research enabled managers to reduce hydrilla to about 28,610 acres in (Figure 4) Hydrilla was reported in 194 public waters in 2013 and is considered to be under maintenance control in 98% of Floridas public lakes and rivers; however, tubers infest about 90,000 acres and represent the potential for immediate regrowth. 75% of the hydrilla populations reported in 2013 covered 10 acres or less (Figure 3). Sixty-five percent of the hydrilla reported in 2013 occurred in the four lakes of the Kissimmee Chain of Lakes, among Florida s largest and most important multiple-purpose waterways. Managers spent $7.43 million treating about 14,150 acres of hydrilla in Florida public lakes and rivers during to conserve the multiple uses of these resources (Tables 1-3). The Florida Exotic Pest Plant Council lists 12 Category I invasive plants, capable of disrupting aquatic ecosystems and causing harm in Florida public waters. Seven Category I plant species in addition to hydrilla, water hyacinth, and water lettuce were detected covering about 6,670 acres in 91% of Florida s public waters in $2.74 million were spent managing about 6,670 acres of aquatic plants other than hydrilla and floating plants during (Tables 1-3). Most for the control of tussock-forming plants like frog s bit, burhead sedge, and tropical American water grass in Lakes Okeechobee, and the Kissimmee Chain of Lakes, and floating islands and tussocks in Tsala Apopka to conserve fish and wildlife habitat and navigation in the extensive marsh systems of these waters. 3

6 Floating Plants Figure 1: Number of Public Lakes and Rivers in which Floating Plants Were Reported in 2013; Reported by Range of Population Size. 153 of the 255 floating plant populations reported in 2013 covered less than one acre. This is significant in that few floating plant populations are not under maintenance control. Those waters with large floating plant levels reported in 2013 are high priorities to regain control in # of Populations < >500 Hyacinth Acre Ranges Figure 2: of Hyacinth Reported in Florida Public Lakes and Rivers from hyacinth reached its apex, covering more than 125,000 acres in the early 1960s. Frequent and consistent management efforts coordinated on a statewide basis have allowed managers to reduce the standing crops of water hyacinth and water lettuce to low levels where they do not impair the multiple uses of Florida waters. (thousands) Year Hydrilla Figure 3: Number of Public Lakes and Rivers in which Hydrilla Was Reported in 2013; Reported by Range of Population Size. 146 of the 194 hydrilla populations reported in 2013 covered 10 acres or less, signifying that most that are under maintenance control are at very low levels. Populations exceeding 100 acres are the higher management priorities for # of Populations < ,000 >1000 Hydrilla Acre Ranges 5

7 Figure 4: Reported and Managing Hydrilla in Florida Public Lakes and Rivers from Hydrilla Funds Expended (thousands) (millions) Year When funds are sufficient, hydrilla can be managed at a low level. When funds decline, hydrilla expands to a higher level requiring additional recurring funding for control. Hydrilla reached its apex in Florida public waters in 1994, covering nearly 100,000 acres. Although the standing crop in the collective 194 waters in which hydrilla was reported in 2013 totaled about 28,610 acres, underground tubers, that represent hydrilla s ability to immediately sprout and refill the water column, are estimated at about 90,000 acres. 6
