My methods are to map the area, and have a good corner to start from. I also put it down on
a topo map to determine the best method for taking plots. I run N-S or E-W lines and use a
compass and pace. 10% sample comes out to about a plot every 200'. While running lines I
can make note of where the existing roads are, the changes in timber type, and any other
pertinent info. It works well for me, but I wouldn't want to do it when there are a lot of
leaves. I also record dbh, tree grade, species, ht, and whether I would consider marking at
this time. When put against an actual 100% cruise, I can get within 5%.
You are right that a mgmt plan would cost more than a general cruise, and your figures are
good for New England. Down here you can't sell most landowners a mgmt plan and we have no
