Tree Pruning Classifications?

[SirTreeRat]

Where can find the Standards for the classifications of types of tree pruning?

I know there use to be Like Class-1, Class-2

But, I've been told they have changed or are going to change.

Anyone know?

A300 pruning standard from ANZI. You should be able to find it on your chapters ISA site or even the main ISA too. I think this might be what your looking for never heard of them called class 1 or class 2.

Pruning Classes were used in the old pruning specification.
They were put out but the NAA, with help from other organizations probably. These predated the A-300 pruning standards and were phased out.

I'm not sure of dates since I can't find my copies.
