The following measurements are recorded in the Poona babul forest 

 working plan,^ though the working plan officer does not place absolute reliance 

 on them since they are based on ring-countings : 



Berar. Mr. Shrinivasulu Nayadu ^ says that in Berar generally speaking 

 a babul crop attains a height of 12 to 15 ft. in ten years, and estimates that 

 with proper cultural attention babul crops ought to produce about 1 ton or 

 40 cub. ft. per acre per annum. In the Loni Bhongaon range working plan 

 the mean annual radial increment is estimated from ring-countings to be 

 019 in., and the average yield of timber and fuel in existing coupes is estimated 

 at 470 cub. ft. solid per acre. 



Sample plot measurements extending over four years in the Akola forest 

 division gave the following results :
