Ayatollah Ali Khamenei Supreme Leader of the Islamic Republic of Iran
c/o H.E. Mr. Gholamali Khoshroo Ambassador and Permanent Representative of the Islamic Republic of Iran to the United Nations Permanent Mission of the Islamic Republic of Iran to the United Nations 622 Third Avenue, 34th Floor
New York, NY 10017, USA
Your Excellency:
We are an international community of conservation practitioners and scholars. We all chose this path out of sheer love and passion for wildlife and the natural environment, both of which are increasingly under pressure in many regions of the world. We work in many such places, in order to address these challenges in close collaboration with national scientists, conservationists, and governmental organizations. Many of us have worked in Iran in the past.
Nine months ago, our colleagues Houman Jowkar, Taher Ghadirian, Sepideh Kashani, Niloufar Bayani, Morad Tahbaz, Amirhossein Khaleghi Hamidi, Sam Radjabi, Abdolreza Kouhpayeh, and Kavous Seyed Emami, were arrested and have since been in prison, with Mr. Seyed Emami regrettably passing away during that period. Four of them are now charged with “sowing corruption on earth”. We understand these charges are in connection to conservationists using tools of science, such as camera traps, which are suspected of having been used to undermine the national security interests of Iran. Camera traps are now a standard tool for wildlife monitoring, being deployed for that purpose in many regions around the world. Camera traps deliver invaluable, first-hand evidence on the presence of endangered species when they approach within a few meters. They are an essential tool in providing a critical basis for both science and conservation strategies to save species from extinction.
All of the conservationists in question have dedicated their lives to the conservation of wildlife in Iran, including the critically endangered Asiatic cheetah. Throughout their careers, they have always promoted the image of Iran in the international conservation community and applauded its efforts to conserve wildlife while facing many other challenges. They have also inspired young biologists and conservationists in Iran to follow in their footsteps. To the best of our knowledge, our colleagues have worked and carried themselves with the highest moral integrity.
We are convinced that their work and research had no second means or objectives. Given the general international political backdrop and sometimes tense relationships between countries, we fully understand the current concerns. We are horrified about the thought that the neutral field of conservation could ever be used to pursue political objectives. We as a community strongly condemn that, and we are convinced our colleagues had no such part.
We stand by the innocence of the conservationists in question and urge you to call for a fair and just evaluation of the evidence, access to lawyers of their choice and a transparent trial. Some of us are ready to provide evidence and witness testimony upon request.
Sincerely
CC:
The Honorable Ayatollah Sadeqh Larijani Head of the Judiciary of the Islamic Republic of Iran Howzeh Riyasat-e Qoveh Qazaiyeh (Office of the Head of the Judiciary)
Pasteur St., Vali Asr Ave. (south of Serah-e Jomhouri) Tehran 1316814737
