In an effort to meet our obligation to protect populations of endangered species from over-collection, some of our specimen data (such as specific locality information) have been removed from those online records for endangered species. These data are made available to researchers . We are aware that making our herbarium specimen data available involves striking a delicate balance between access to data that are important to research and the potentially reckless posting of sensitive information. To that end, we are in the process of removing portions of records for species listed in the United States Federal Endangered Plant Species list and in the IUCN Red List of Threatened Plants. These two lists, however, are not comprehensive. If you are aware of other species that are better protected by limiting access to specific locality data, please contact us, and we will update our database accordingly. We have also removed portions of information from records of species from groups such as Orchids, Cycads (including Zamiaceae) and Cacti, which are often subject to over-collection. Please note that we have removed specific locality information from all species in these groups, even those that are not explicitly listed as endangered.
