Hydrilla & Hygrophila
Attention all boaters, duck hunters, water skiers, lakefront home owners, environmentalists, and anyone else with an interest in Florida's waterways and aquatic ecosystems: What do you know about HYDRILLA and HYGROPHILA, a.k.a., the "Terrible Twosome"?
Aquatic invasive weeds are a major problem in lakes, canals, rivers, and essentially any type of water body in Florida, particularly, hydrilla and hygrophila. The "Terrible Twosome" have been problematic in Florida waterways since the 1950's, spreading rapidly through the state, distributing havoc with every inch of spread. That may sound a little harsh but these plants cost millions of dollars per year to manage. According to the Invasive Plant Management Section, roughly $28 million was spent in 2007 for aquatic plant control in public waters, 36 percent of that, or $10 million, was for hydrilla control! It will cost close to $30 million to manage invasive aquatic weeds in 2006/07.
Osceola County was awarded a grant to find new and alternative methods of control for hydrilla and hygrophila in the Kissimmee Chain of Lakes.
