Some examples of invasive species from various parts of the world. Use the tag 'invasive species'.

An invasive species is generally one that is not native to that region and their introduction is likely to cause damage to the existing ecosystem. In UK, for example, Japanese Knotweed is an invasive species that can cause disruption especially in urban areas, it is estimated that the cost of removing it from the Olympic park in London was £70million.

Many non-native or alien plants and animals arrive in new areas but generally only a small proportion become problem invasive species. Some species have moved around the planet with man and are now major problems in many areas, an example is the brown rat, one of the most successful species on earth. While writing this description I was somewhere between 1 and 6m away from the wild brown rat shown in the picture.
