Conclusion• Comparing forest conversion before and after
inscription as a World Heritage site, the analysis
found that forest conversion trend is positive to Outstanding Universal Value (OUV) of the World
Heritage criteria
• Within the core area, an old clearing site has
been rehabilitated by a forest Plantation Project
and natural succession
• Forest loss has occurred in around the edges and
buffer zone of Thap-lan National Park, but this might not impact the OUV of World Heritage site
Conclusion• Forecasting land use change for the next 20 years
found that future land use change in Thap-lan
National Park might have a small negative impact
on OUV
• The results of this study could be used for land use
planning in order to protect the natural World Heritage site for the long-term
