    Your results mention that 9 species were encountered during surveys. C. galbinifrons, G. spengleri, M. impressa, and P. steindachneri are mentioned in the text. What were the other 5 species found during surveys?

      We have missed to give other species: Cyclemys oldhami, Sacalia quadriocellata, P. sinensis, P. megacephalum, and C. mouhotii. A highlight that, we found only and G.spengleri in the wild. the rest were from village observation
      Thank you for your comments.

    I am to assume the forest you surveyed is not a protected area? With 9 different turtle/tortoise species, this sounds like a high priority area for protection / wildlife enforcement.

      Hi Billy,
      Yes, the forest was not a protected area. It is true that this area is very priority for the wildlife protection. But the goverment has invest to established a protected area which about 12km away from this area. I have already recommends the provincial to enlarge the existent protected area. However, the financial limited is very problematic. I myself can’t do a big project to establish a protected area

        Hi Thong,

        Good to hear from you and glad to know that there are protected areas nearby. With all the information / data you have collected, what is your next step?

        • Thong Van Pham on August 7, 2020 at 5:44 am

          Well, we have written the data in a paper and awaiting for peer review. For further conservation action, we would propose that area to be a nature reserve that will be corridor to connect other NRs around (including an important Protected area in Northern Laos)

    What is the typical habitat that make the area so divert?

    • Thong Van Pham on August 26, 2020 at 4:28 am

      Hi Sadie,
      Thank for your question, the habitat here typical a tropical forest hill which divert by mix bamboo forest, evergreen forest and many stream, rivers going around lead the area to be very divert in turtle fauna. The topography also typical as it is wide range of elevation from 200-1500m a.s.l
