I dont know...well
If you want to know how to find the BSA of a woodlot you can do this.
Take a dime and hold it about 24 inches from your eye width way. Then count each tree that is as wide or wider than that dime. Times the total by 10 and that gives you the BSA of that area. BSA=Basil Square Feet per Area.
In some regions, the BSA should be 70, in others lower. Like AZ where it should be real low. In some forests (Hardwoods for example), If the BSA is over 70, then you need to cut some out to lower the BSA to about 70.
In the northern Hardwood Forest, depending on the hardwood class, I like to see it at 60 for a class ‘A’ stand-that is a stand with mixed mature/young trees. In a young stand, 70. This is something I have argued about with foresters for years now..especially now since the youngsters think they know it all since they have learned it out of a book.
You need to do several plots around the lot and average it out to find the Average BSA. Take plots on thick areas and plots on thin.
I got 45 years in the business and have worked in AZ for a year near Flag doing those cuts. One was next to the Fairgrounds..Fort, or whatever they called it-I cant remember the name-The Lake Mary Road we did another. Worked up in the Bradshaws near Prescott by the YMCA camp also-the Old Senate road I think they called it.
Some timber types require clear cut- Most Aspen and many softwoods. Oak does best with a darn good cut.
Its all in the experience a person has.
“Then count each tree that is as wide or wider than that dime.”
Do you look in all directions or choose just the area in front of you to do this?
