Species that are protected under the Nature Conservation Ordinance 4 of 1975 and Amendments are indicated in the database.
Plants on the Forest Act 12 of 2001 and Amendments are also noted. This Act repeals all previous Forest legislation (Preservation of Trees and Forests Ordinance No. 37 of 1952 and the Forest Act 72 of 1968) where specific trees were listed as protected, but the situation is not clear regarding species protected under the new Act (2001), although passed through Parliament, it is however not yet in force and does not have any guidelines listing species protected under it. We have indicated which species were formerly protected under the Forest laws.
