Pollination of an invasive plant

The movement of plants around the globe for agriculture, forestry and horticulture has in some cases resulted in the accidental spread of aggressive species into natural communities. These invasive species are considered to be an important threat to native biodiversity. It is very difficult to predict whether a particular type of plant will become invasive, but one of the main factors is whether or not it can reproduce successfully in its new habitat. For those plants that are animal pollinated, the ability to recruit suitable pollinators is clearly important and it is thought that generalised species (which can be pollinated by a wide range of different types of animal) are more likely to become invasive than more specialised species.
