Problem Plants

A problem plant is any plant, shrub or tree which has a negative environmental impact in a particular locality. The main negative impacts of problem plants are invasiveness i.e. the supplanting of naturally occurring species and subsequent loss of bio-diversity, and excessive water consumption.  Most invasive plants are alien to the biomes in which they thrive, but some indigenous species such as Acacia nilotica can become invasive as a consequence of poor grassland management practices.
