The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...

Invasive species in Florida are introduced organisms that cause damage to the environment, human economy, or human health in Florida. [1] Native plants and animals in Florida are threatened by the spread of invasive species. [2] Florida is a major biodiversity hotspot in North America and the hospitable sub-tropical climate has also become a ...
Exotic species control falls under the management of the U.S. Fish and Wildlife Service, which has been compiling and disseminating information about invasive species since 1994. Control of invasive species costs $500 million a year, but 1,700,000 acres (6,900 km 2) of land in South Florida remains infested. [5]
