Information on the flora of Swaziland has been gradually improving over the years, resulting in better information on which to base lists of threatened species.
The list of species included in the Southern African Plant Red Data Lists, published by SABONET in 2002 (see Flora Red Data Lists) is already in need of an update, and on a global level, the IUCN Red List of Threatened Species information is even more out of date.
The legislation for the protection of indigenous flora was updated in 2000.
This replaced The Flora Protection Act of 1952.
The IUCN Red List of Threatened Species lists the following threatened species for Swaziland:
