The way we live

Increasing our chance of becoming the victims of flood

A number of riverside and aquatic invasive non-native plants are widely considered to increase the risk of flooding.  They do this by clogging water courses with plant material or sometimes by causing riverbank eroding which leads to a build up of sediment.  Some animals may also contribute to the risk of flood.

In urban environments, invasive non-native species can be aesthetically detrimental.  Ponds clogged with invasive water plants can reduce their appeal and some species, such as Japanese Knotweed, can encourage deterioration in the built environment.
