Where are invasive species typically found?

Invasive species can be found in any type of environment. Plants can invade crop fields and rangelands as well as native habitats; invasive fish are found in rivers, lakes, and oceans; and invasive micro-organisms like Sudden Oak Death invade forests and plant nursery stock.


Invasive species are often most plentiful in cities and ports where people are more likely to move species around, but they are also found in remote wilderness where they may have been accidentally carried by visitors or hitched a ride on native animals. Unfortunately, some invasive species are even being sold in local garden stores and nurseries where they are bought and planted in urban environments such as yards, gardens, and retail spaces including shopping centers, restaurants, and movie theatres.
