Sap Ladder questions

[ldick]

I am trying to understand how a sap ladder works and under what conditions they make sense and/or problem they are designed to solve. Can someone point me to information that will help me understand sap ladders? Thanks in advance.

try doing a search on Sap Ladders, i would guess there has to be over 100 pages on it

Check out the Proctor Maple Research page they have pictures and they might even have some information on how they work. http://www.uvm.edu/~pmrc/?Page=pictures.htm
