Invasives in Lake Istokpoga

     Florida- Officials say Lake Istokpoga would become a marsh if it weren't for herbicide treatments and other control efforts. Dealing with hydra, pickerelweed, spatterdock, primrose willow, cattail and water hyacinth, local efforts have gone towards clearing shoreline areas and other trouble spots in Highland County's largest lake. And while lakes do naturally progress into marshes (at least in areas where sunlight is capable of penetrating to the bottom), the progress at Lake Istokpoga is being sped up by the presence of so many invasive and nuisance species. 

     Which is a problem not only for the environment, but for the local economy. The lake has a impact measured at $39 million annually; attracting on average 190,000 boaters a year, with 60% of them coming from outside the county. Of those who responded to a survey, 24.3% of the respondents say they would not return if 25% of the lake were covered (rendered unusable for most recreation), while 53.1% said they would not return if coverage increased to 75%.
