IUCN Red List of Threatened Plants 1997
This searchable database makes available 35,319 records from the WCMC Threatened Plants Database of plants that are recorded as globally threatened. The Threatened Plants Database contains information on over 136,000 plant taxa of conservation importance. The site also provides summery statistics of threatened plant species
Not as up to date as the IUCN Red List of Threatened Species (in which work to convert endangered plants data to the same standard has begun) it is still a valuable resource for those interested in the conservation of plants.
