3. The Objectives
Study on The Forest Conversion in
Thap-lan National Park after World
Heritage Inscription (2006 – 2014)
Mapping the risk area
Create new forest type map of the
PA in Dong PhayaYen – Khaoyai
Forest Complex

4. Method
 Informed by LANDSAT satellite imagery
 Classification of plant Community and
other Land use patterns were analysed
by comparing the imagery during 2006
and 2013.

6. The Results
Forest types in Thap-lan NP
Land use change
Risk areas

56. Areas at risk for future land
conversion

59. Conclusio
n• 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

60. Conclusio
n• 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
