The IUCN/SSC Plant Conservation Sub-committee directs the work of the Plants Programme under the umbrella of the IUCN/SSC Plant Conservation Strategy. Much of the Programme's work is implemented by approximately 30 Plant Specialist Groups and the Plant Red List Authorities. Although Fungi and Lichens are not technically “plants," that is they belong to a separate taxonomic Kingdom, their conservation is also a major concern within the Plants Programme.
