Generate reportList of Species
Top of pageThe table lists the species recorded in the Compendium for this region (from the full species datasheets). It includes species that are invasive in this region, those for which there is no data on invasive status, and also species that are not invasive in the region but are reported as invasive elsewhere. This summary table is based on all the information available. When several references are cited, they may give conflicting information on the distribution record. For further information, please follow the link to the datasheet.
