Thanks for the info Big J and Andrew. I'll keep in mind the variations on growth due to site etc. The link to the carbon code web page is really useful 👍

Thanks daltontrees - that's a good point about dried wood, I'll have a look into research on that angle too. As for my conclusion, I'm not sure until I've looked into it more but I presume some tree species will store more carbon than others.

Hi everyone, thanks very much for getting back to me! The purpose of the research is to estimate how much carbon different tree species would store over 30 years from being planted as small whips. If I know their DBH at 30 years I can use this to calculate the carbon they have (theoretically) stored and then see which tree species stored the most and least. I realise this will depend a lot on location, soil, site etc, but it was just an average DBH that I needed. It's for an environmental science project assignment, from the angle of carbon sequestration for climate change purposes. Thanks for suggesting the Forestry Commission publication by John Whyte, I'll take a look at it. It's great the FC have so many books available as free PDFs, some very interesting reading. I'll have a look at the Forestry Scotland database too - that sounds interesting! Someone else has also suggested the yield tables used in the Forest Yield software so I can hopefully get hold of these and work it out manually without spending £50 🙂 Thanks again for your help!

Hi everyone, I am doing a student research project for my degree and came across this forum which pointed me in the direction of some very useful Forestry Commission PDFs (thank you!). I just wanted to ask a quick question as you all seem so knowledgeable! Is there an easy way to estimate a tree species' diameter at breast height at a certain age? I would like to be able to create a list of different tree species and say (on average) what their DBH would be when they are 30 years old. E.g. Average English Oak at 30 years = 100 cm DBH Average Wych Elm at 30 years = 70 cm DBH Etc. Could anyone suggest a way to do this please? Ideally I would like to make a list of several UK tree species and estimate their DBH when they are 30 years old. Thanks in advance for your help! I feel like I’m going around in circles trying to find the info online. I've seen the Forest Yield software programme which looks like it might do what I need it to do but it costs £50 + VAT.
