I am looking for the book or a link to the man-dbh-type of work-type of tree flow chart that the NAA put together back in the eighties. I had it saved as a pdf that i got from some one on this site years ago, but my computer crashed and i lost the info.
this is an except from an article that references the book, flow charts, and tables. The name of the book is excluded.
"Following is a chart indicating representative average fixed and variable times to Class II (medium prune) various sizes of trees. Analyze the performance of your crews and adjust the average man-hours required for each size and pruning class to fit your circumstances. Base the figures on your average crew's performance on a normal day. Every crew has good and bad days, and all crews vary in productivity.
Table 1 illustrates the procedure in its simplest form for figuring an estimate for two men to prune two trees. For this example, 14.8 manhours are required to perform the two tasks of medium prun- ing a 16" oak and a 30" maple."
