The analysis of the area at risk of illegal logging of Rosewood and Padauk wood in Tham Pha Thai National Park has utilized geospatial information data related to eight factors. These factors include the distribution of valuable wood, distance from the locations of Rosewood and Padauk wood case, distance from road, distance from village, distance from the National Park Protection Unit, distance from water body, slope, and Normalized difference vegetation index (NDVI).

Based on the study, it was found that there were five levels of risky areas, including the riskiest area of 199.72 square kilometers, very high-risk area: 336.18 square kilometers, medium-risk area: 337.98 square kilometers, low-risk area has an area of 227.13 square kilometers, and least-risky area has an area of 113.87 square kilometers. The areas of riskiest and very high-risk are found around the edge of the park. The findings of this study can serve as a database for planning and implementing strategies the prevention and suppression of illegal rosewood in the area.
