Introduced and invasive species of Burkina Faso

The list of introduced and invasive species has been extracted from information on distribution and origin of the species as documented in the Catalogue des Plantes Vasculaires du Burkina Faso (Thiombiano, Schmidt et al. 2012) and combined with occurrence records from the West African Vegetation Database (Janssen et al. 2011, Schmidt et al. 2012) to give a measure of frequency. All species with less than 5 records have been omitted, as they were considered not to be sufficiently established. Many of these species are weedy, often found in disturbed sites, such as roadsides, segetal or ruderal habitats and the most frequent ones can well be considered invasive.
