EXECUTIVE SUMMARY This is the final report of a herpetodiversity research, which was commissioned by GIZ Hin Nam No National Project. The herpetology research team undertaken 33-day field work in four sites within HNN NPA between March and April 2017. Based on the specimen identification and direct observation in the field, we recorded a total of 55 species (33 species of reptiles and 22 species of amphibians) from HNN NPA. To combine with the results from previous studies, the species number of the herpetofauna of HNN NPA is 71 (44 species of reptiles and 27 species of amphibians). Among four survey sites Nong Ma has the highest number of recorded species (32), followed by Dou (22), Nong Ping (22), and Thong Xam (17). The research team also found 15 new records for the herpetofauna of HNN NPA. Remarkably, the specimen of Keelback snake collected in Nong Ma may represent a second specimen of Hebius andreae described by Ziegler & Le more than 10 years ago. Statistic analysis showed that herpetofauna of Thong Xam is similar to that of Nong Ping and the highest difference is between Thong Xam and Nong Ma. In comparison with this data from PNKB NPA we found that 6 reptile species are only known to occur in HNN NPA only. Four of them are endemic species on the western side of the Annamite Mountain Range. Threatened species: Among 71 species recorded from HNN NPA, seven species are being globally or nationally threatened: seven species listed in the IUCN Red List (2017) and two species in the Appendix II of CITES (2017). Although the number of threatened species is not so high (ca. 10% of the total species), they are very rare in the wild. Recommendations for biodiversity conservation: • Support for further herpetodiversity research • Identification of priority areas for biodiversity conservation ບົດລາຍງານການສໍາຫຼວດສັດເຄ ິ່ງບົກເຄິ່ງນໍ㛉າ ຜົນການສໍາຫຼວດຄວາມຫຼາກຫຼາຍຂອງສັດເຄ ິ່ງບົກເຄິ່ງນໍ㛉າ ໃນປ່າສະຫງວນແຫ່ງຊາດຫີນໜາມໜ 㛈 ແຂວງ ຄໍາມ່ວນ, ປະເທດລາວ ບົດລາຍງານຫຍ 㛉 ນີີ້ແມ່ນບົດລາຍງານສະບັບສົມບູນຂອງການສຶກສາຄົີ້ນຄ້ວາສັດເຄ ິ່ງບົກເຄ ິ່ງນໍ㛉າ ແລະ ສັດເລືອຄານ ທີິ່ໄດ້ຮັບການມອບໝ າຍໂດຍໂຄງການຈີໄອແຊັດຫີນໜາມໜ 㛈. ທີມງານສຶກສາຄົີ້ນຄ້ວານີີ້ໃຊ້ເວລາ 33 ວັນໃນການເຮັດວຽກພາກສະໜາມ ພາຍໃນ 4 ພືີ້ນທີິ່ທີິ່ຢ່ ໃນເຂດປ່າສະຫງວນແຫ່ງຊາດຫີນໜາມໜ 㛈ໃນຊ່ວງລະຫວ່າງ ເດືອນ ມີນາ ຫາ ເດືອນ ເມສາ 2017 ອີງຕາມການຈໍາແນກຕົວຢ່າງຂອງຊະນ ດພັນ ແລະ ການສັງເກດຕົວຈ ງໃນພາກສະໜາມ ພວກເຮົາໄດ້ບັນທຶກທັງໝົດມີ 55 ຊະນ ດພັນ (ສັດເລືອຄານ 33 ຊະນ ດພັນ ແລະ ສັດເຄ ິ່ງບົກເຄ ິ່ງນໍ㛉າ 22 ຊະນ ດພັນ) ຈາກປ່າສະຫງວນແຫ່ງຊາດຫີນ ໜາມໜ 㛈. ເພືິ່ອສົມທົບກັບຜົນໄດ້ຮັບຈາກການສຶກສາຄົີ້ນຄ້ວາໃນເມືິ່ອກ່ອນ, ຈໍານວນຊະນ ດພັນຂອງສັດເຄ ິ່ງບົກເຄິ່ ງນໍ㛉າຂອງປ່າ ສະຫງວນແຫ່ງຊາດຫີນໜາມໜ 㛈ແມ່ນ 71 ຊະນ ດພັນ (ສັດເລືອຄານ 44 ຊະນ ດພັນ ແລະ ສັດເຄ ິ່ງບົກເຄ ິ່ງນໍ㛉າ 27 ຊະນ ດ ພັນ). ໃນບັນດາການສໍາຫຼວດພືີ້ນທີິ່ 4 ແຫ່ງນີີ້: ເຂດໜອງມ້າມີການບັນທຶກຈໍານວນຊະນ ດພັນຫຼາຍກວ່າໝູ່ (32 ຊະນ ດ ພັນ), ຕ 㛈ມາແມ່ນ ເຂດບ້ານ ດຸ (22 ຊະນ ດພັນ), ເຂດໜອງປິງ (22 ຊະນ ດພັນ) ແລະ ເຂດທົງຊໍ㛉າ (17 ຊະນ ດພັນ). ນອກຈາກນັີ້ນ ທີິ່ມງານສໍາຫຼວດກ 㛈ໄດ້ຍັງມີການບັນທຶກໃໝ່ຈໍານວນ 15 ຊະນ ດພັນສໍາລັບສັດເຄ ິ່ງບົກເຄ ິ່ງນໍ㛉າຂອງປ່າ ສະຫງວນແຫ່ງຊາດຫີນໜາມໜ 㛈. ໂດຍສະເພາະແມ່ນ ຕົວຢ່າງຊະນ ດພັນງ ທີິ່ໄດ້ເກັບກໍາໃນເຂດໜອງມ້າອາດຈະເປັນ ຕົວຢ່າງຊະນ ດພັນທີສອງຂອງ Hebius andreae ທີິ່ໄດ້ອະທ າບໂດຍ ທ່ານ ຊ ກເລີ ແລະ ເລ ໃນເມືິ່ອຫຼາຍກວ່າ 10 ປີ ກ່ອນ. ການວ ເຄາະທາງດ້ານສະຖ ຕ ສະແດງໃຫ້ເຫັນວ່າສັດເຄ ິ່ງບົກເຄ ິ່ງນໍ㛉າໃນເຂດບ້ານທົງຊ㛉ໍາແມ່ນຄ້າຍຄືກັບເຂດບ້ານໜອງປິງ ແລະ ມີຄວາມແຕກຕ່າງກັນຫຼາຍລະຫວ່າງເຂດບ້ານທົງຊໍ㛉າ ກັບ ເຂດບ້ານໜອງມ້າ ເມືິ່ອສົມທຽບຂ 㛉ມູນນີີ້ໃນອຸທ ຍານແຫ່ງຊາດຟອງຍາແກບ່າງ ພວກເຮົາໄດ້ເຫັນວ່າ ມີສັດເລືອຄານ 6 ຊະນ ດແມ່ນຮູ້ວ່າມີ ພຽງຢູ່ໃນປ່າສະຫງວນແຫ່ງຊາດຫີນໜາມໜ 㛈ເທົານັີ້ນ ເຊ ິ່ງໃນນັີ້ນມີ 4 ຊະນ ດພັນທີິ່ເປັນຊະນ ດພັນສະເພາະຖ ິ່ນໃນເຂດ ເບືີ້ອງຕາເວັນຕົກສ່ຽງເໜືອຂອງສາຍພູຫຼວງ. ຊະນ ດພັນທີິ່ຖືກໄພຂົມຂູ່: ໃນບັນດາ 71 ຊະນ ດພັນທີິ່ໄດ້ບັນທຶກຈາກປ່າສະຫງວນແຫ່ງຊາດຫີນໜາມໜ 㛈 ມີ 7 ຊະນ ດ ພັນທີິ່ກໍາລັງຖືກໄພຂົມຂູ່ຂອງໂລກ ຫຼື ພາຍໃນປະເທດ: ມີ 7 ຊະນ ດພັນທີິ່ໄດ້ຂືີ້ນບັນຊີແດງຂອງອົງການ IUCN (2017) ແລະ ມີ 2 ຊະນ ດພັນທີິ່ລະບຸໄວ້ໃນເອກະສານຊ້ອນທ້າຍ II ຂອງ CITES (2017). ເຖ ງແມ່ນວ່າຈໍານວນ ຊະນ ດພັນແມ່ນຍັງບ 㛈ທັນຫຼາຍ (ປະມານ 10%ຂອງຊະນ ດພັນທັງໝົດ) ແຕ່ວ່າພວກມັນເປັນຊະນ ດພັນທີິ່ຫາຍາກຢູ່ໃນ ປ່າ. ຄໍາແນະນໍາສໍາລັບການອະນຸລັກຊີວະນາໆພັນ: • ການສະໜັບສະໜູນສໍາລັບການສຶກສາຄົີ້ນຄ້ວາກ່ຽວກັບຄວາມລາກຫຼາຍຂອງສັດເລືອຄານ ແລະ ສັດເຄ ິ່ງບົກ ເຄ ິ່ງນໍ㛉າໃນຕ 㛈ໜ້າ • ການກໍານົດເຂດພືີ້ນທີິ່ບຸລ ມະສ ດສໍາລັບການອະນຸລັກຊີວະນາໆພັນ TABLE OF CONTENT ACRONYMS AND ABBREVIATIONS ........................................................................................................... i EXECUTIVE SUMMARY ............................................................................................................................... ii ACKNOWLEDGEMENTS ............................................................................................................................. iii 1.
