Troup : Teak Forests of Burma.

interesting to note that the three richest teak forests in Burma are 
situated on flat alluvial land where bamboos are scarce or absent. The 
three forests in question are :— 
(1) Mohnyin Reserve, Katha Division . . 707 trees per 100 acres. 
(2) Satpok Reserve, Tharrawaddy Division . 455 trees per 100 acres. 
(3) Kangyi Reserve, Zigon Division . . 441 trees per 100 acres. 
Of the forests of the upper mixed type there are two with over 400 
sound trees 3 feet in girth and over per 100 acres : these are 
(1) Bondanng Reserve, Toungoo Division . 409 trees. 
(2) Kadinbilin „ Tharrawaddy Division . 408 trees. 
There are no fewer than 9 forests with totals of between 300 and 400 
trees per 100 acres ; these are all situated in the Pegu Yoma except the 
Ziyaing Mehaw reserves, and all are of the upper mixed type. 
(c) Forest rich in small-sized teak .—As mentioned above, a very ac¬ 
curate comparison of the number of small-sized teak in different forests 
is not always possible, as so much depends on the season in which the 
enumerations were carried out. The figures in Appendix II, however, 
reveal one or two interesting facts. First, as regards the Pyinmana 
reserves of the Pegu Yoma : although the heavy over-working of the 
past has considerably depleted these reserves of large trees, it is to be 
noted that reproduction is springing up in profusion, aided no doubt 
by the openings made in the overwood, the constant breaking down 
of bamboos by innumerable elephants, and the wounding of the soil 
during extraction. The figures, indeed, show that in the eight reserves 
concerned in no case is the crop of young teak under 3 feet in girth less 
than 768 plants per 100 acres : in only two other reserves in the Province 
is that number exceeded, namely in Bondaung reserve (799) and 
Kangyi reserve (2,920). 
In these same Pyinmana reserves it is to be noted that the quantity 
of small teak in the drier forests of the north, particularly in the Sinthe 
reserve, is greater than it is in the moister reserves in the southern half of 
the Division ; this merely bears out the well-known fact that in the drier 
and therefore opener teak forests reproduction ordinarily springs up in 
greater profusion than in the moister and denser forests. 
The profusion with which reproduction is springing up in the Kangyi 
reserve is remarkable ; this is to be contrasted with the state of affairs 
in the Mohnyin reserve, where reproduction is very poor in comparison, 
although these two reserves resemble each other in being both situated 
on alluvial land and being both exceptionally rich in large-sized teak.
