The IUCN Red List provides consistent criteria to assess the threat status of all wildlife. The IUCN Bumblebee Specialist Group aims first and foremost to complete a status assessment for all ~250 species of bumblebees worldwide using the IUCN Red List Categories and Criteria. With Regional Coordinators facilitating the data collection for each region, the Specialist Group will place each species of bumblebee into one of nine categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient, or Not Evaluated.
IUCN Red Listing Materials
Red List Categories
Below are some IUCN resources that can help by describing the process:
When you are ready to assess a species of bumblebee, you will enter the data directly into the Species Information Service (SIS) database.
Here is an example red list assessment, which was completed by Elaine Evans of The Xerces Society in 2009 for Bombus affinis. The current assessment form, which differs slightly from the one used in the 2009 example above, is available from the IUCN upon request.
In 2009, Paul Williams and Juliet Osborne published a study of the conservation status of bumblebees worldwide. The preliminary conservation status of each species is summarized in Table 1 of that paper. This was a preliminary outline study and we look forward to doing a more complete assessment together.
A listserv has been set up to facilitate communication among the BBSG. Regional Coordinators have been automatically subscribed to the listserv. If members would like to join the listserv, please send a request to Sarina Jepsen. Once you are a member of this listserv, you can post a message to the entire listserv by sending an email to: email@example.com.
