What is an invasive species?
As nutria began to invade the swamps of Louisiana through the 1940s and 50s, they quickly made themselves known and began to cause significant damage to the land. To be considered an invasive species, an animal must meet a few criteria. First, they must cause major disruption to the ecosystem around them, physically degrading the health of said ecosystem. Next, the animals will not be native to the area in which they are wreaking havoc, and finally, once the invasive animal is introduced to the area, it will cause significant environmental harm and sometimes even harm to human health. The nutria quickly met all the criteria and within less than three decades, earned themselves the “invasive” title.
