Sorry, I clicked to too soon. I can provide more detail via Excel. I will try to add a screen capture of part of an Excel worksheet showing Ailanthus dry weights for wood and bark and their associated water components. Here goes. I'll try to add a file.
@Elaheh Daghighi Specific Gravity and Other Properties of Wood and Bark for 156 Tree Species Found in North America by Partick D. Miles and W. Brad Smith. United States Department of Agriculture, Forest Service. Northern Research Station, Research Note NRS-38, October 2009. I can share the Excel worksheet that computes the values in the columns. Attached is an expanded screen print of what I previously sent.
