A couple of times I have read in this forum people stating as some kind of fact that pitch is something that comes exclusively from conifer trees and sap only comes from deciduous trees.
I say hogwash.
I have never heard or read any evidence to back up this statement.
In fact I have never heard anybody make such a claim before except the couple times in this forum.
I only protest because I think forums like this should be helping people with useful and factual imformation, not for speading some homegrown myths.
Conifers contain sap just like any other tree or plant.
Pitch, in reference to trees, simply refers to the highly viscous or resinous state of some tree SAP (particularly conifers).
If you disagree and can prove it somehow, I would like to see some sort of evidence. I'm quite willing to be edjumicated.
Here is just a few government and educational references that refer to the SAP of conifer trees.

"......Williams sapsuckers in Colarado fed exclusively on sap and phloem of live conifers."
There are plenty of other links that refer to the SAP of conifers.
