Information on the flora of Eswatini has been gradually improving over the years, resulting in better information on which to base lists of threatened species.

The legislation for the protection of indigenous flora was updated in 2000.

• The Flora Protection Act, 2000
• Schedule A: Especially protected flora (Endangered)
• Schedule B: Vulnerable Flora
• Schedule C: Rare Flora

This replaced The Flora Protection Act of 1952.

With regard to Eswatini red list information, the list of species included in the Southern African Plant Red Data Lists, published by SABONET in 2002 (see Flora Red Data Lists) is in need of an update.

In 2022/2023, draft global red list assessments were prepared for Eswatini's endemic and near endemic flora. The draft assessments can be viewed here. These assessments are awaiting review, and then will be published on the IUCN Red List website.

The southern African status of many species can be found on SANBI's Red List of South African Plants, which includes nearly all of Eswatini's flora.

On an international level, the IUCN Red List of Threatened Species included information on 137 species of plants for Eswatini in August 2017, most of these listed as Least Concern.
