Thai teak sources in the part : Teak Forest (34 Teak) in the Upper Northern Region B.E. 2500 Prof. Dr. Loetsch's inventory of Five Main Teak - Bearing Province . B.E. 2499/2500 (Chiangmai, Chaingrai, Lampang, and Phrae) Teak resources are surveyed and it is found that five provinces have more teaks.
1. Five provinces, namely, Chiangmai, Chaingrai, Lamphun, Lampang, and Phrae, have total area of 61,010 square Kilometers (38 million rais).
2. Forest area which is lower then 1,000 meters from the sea surface level, a level of teak growing and the real teak flourishing area is 26,540 square kilometers (16.5 million rais or 43% of 61,010 square kilometer's area).
3. Five provinces have teaks densely growing approximately 20,259 square kilometers (13 million rais or 33% of 61,010 square kilometer's area) 30 cm high or above, with growing stock of 12 million cubic meters and increment of 300,000 cubic meters per year (0.025 cubic meters per year). But 590,862 cubic meters of them are cut a year (legally 270,763 cubic meters and illegally 320,098 cubic meters) or 2 times of increment, which use up the cost every year. By calculation, the teak has 12 million cubic meter's cost which will be zeroed in the next 40 years or 1987 (B.E. 2530) which is near teak forest cancellation B.E. 2532.

In the part, Thailand was a good-qualified teak resource with area more then 25 million rais generating teaks for domestic consumption and exportation in exchange of currencies for country development over 500,000 cubic meters per annum. Currently, almost all of Thai teak resources are determined to be
conservation areas (most are national parks and wild life conservation areas). The remainders are deteriorated teak forests (sanctuaries), which are closed and the teaks cannot be lawfully taken of out the forests.
