Nutria were introduced to the Louisiana ecosystem in the 1930s, when they escaped from fur farms that had imported them from South America. Nutria were released into the wild by at least one Louisiana nutria farmer in 1933 and these releases were followed by E. A. McIlhenny who released his entire stock in 1945 on Avery Island. [ 51 ]

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]
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 ...
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far.
Due to similar cranial morphology, the nutria was once considered a close relative of the Caribbean hutias and placed together with them in the family Capromyidae. [1] Later, it was more accepted to place it in its own family, the Myocastoridae. [2] Recent molecular studies place them in the family Echimyidae, in the tribe Myocastorini. [3] [4] [5]
They cause serious damage to coastal marshes and may dig burrows in levees. Hence, Louisiana has had a bounty to try to reduce nutria numbers. Large alligators feed heavily on nutria, so alligators may not only control nutria populations in Louisiana, but also prevent them spreading east into Florida and possibly the Everglades. Since hunting ...
