Membership in the TFTSG is by invitation only, based on experience, expertise,
and leadership in freshwater turtle or tortoise conservation and/or biology.

Please contact Peter Paul van Dijk or Brian Horne if you would like to be considered for TFTSG membership. We are especially interested in new members from nations under-represented in the membership, and who are focused on scientific research and/or conservation efforts for tortoises and/or freshwater turtles. We are always interested in new members with turtle and/or tortoise expertise and a passion for their conservation. Turtles are in serious trouble and need all the help they can get. If you feel that you are interested and would like to contribute to our work, please contact us. Although membership is considered an honor earned, it is also a responsibility to participate and to contribute actively to our turtle conservation efforts. We focus primarily on scientific evaluations of status and threats analysis, and help to catalyze conservation action, while avoiding non-scientific advocacy. For more detailed information on the work and activities of the TFTSG, see this link.
