46.1 to 152.1 Range

Page 1015 Table 1
I have never seen values above 80:1 before.
Two other trees were listed:
Saltceder 31:1 to 83:1
Russian olive 15:1 to 30:1

Have a avg ratio of 30:1 but the range is 15:1 for leaf stem to 170:1 for thick part of the branches (2.8inches) for specific species
Most active growing grass/legume/vegetation leaves have an avg ratio of 15-25 to 1, so I think it is safe to assume that said number is the same for tree leaves.
Bark and Heartwood have a avg ratio of 400:1
So if we are talking about a 10ft super-dwarf apricot tree that has a mature thickness of 2.8inches, it really never qualify as a "tree' and will have an avg the same as ramial woodchip of 30:1
If we were to focus on a goumi 'plant' that never really reaches 2inch thickness and is also a Nitrogen fixer similar to legumes the avg ratio will be even lower than raminal woodchip and closer to legumes so 19:1
If you have a oak 'tree' that is young and only 10ft tall it would be considered 100% ramial woodchip and thus 30:1
If that same oak tree was 30yrs old it would only be 20% ramial woochip and 80% regular woodchip so 20% at a 30:1 ration and 80% at a 400:1 ratio for a combined ratio of 326:1
Now if that tree was young and only 18ft it might be 70% ramial woodchip and 30% regular woodchip .........So it depends and you would have to give more specific info.
But seeing as how you said brush. I am just going to avg it and call all of it 3inches or less ramial woochip with a C:N of 30:1
Now rye grass that is freshly cut has a 26:1 ratio but if we sun dry it it goes up to 80:1.
That 80:1 is the same number quoted for dried autumn leaves from trees which makes me think the growing summer leaves have a regular ratio of 25:1
So try not to sun dry the chipped ramial brush, because just like dry rye the ratio will go up to the 80-160 range.
