Is one ton carbon contained by any species of tree locked up 3.67 tonnes of carbon dioxide from the atmosphere???

Vera Barbosa

Yes, one ton of carbon stored in any tree is equivalent to approximately 3.67 tonnes of atmospheric CO2.

What is the regression model for Q. semicarpifolia for above ground biomass calculation?

Vera Barbosa

If you want to calculate the above ground biomass for Q. semicarpilfolia you can follow the method I described in my blog, i.e. measure the radius of the stem in cm(r1) the radius at the top of the stem (r2), and the height of the stem in metres (h); and estimate the tree volume using the equation for the volume of a truncated cone given in the blog. The wood density of oak is 590 - 930 kg/m3, depending on how dry it is; then use the equation: Mass = Density × Volume to calculate the biomass. Hope this helps!

I am wondering that how can we relate the annual tree ring increment with biomass increment? I have data of annual ring increment but cannot convert it into biomass, So is there anyone can help me???

Very informative post and a definite must read for anybody who is interested in how tree's create and produce carbon dioxide, keep up the good work, I will definitely recommend this to my readers.

Again as I said on the previous post wonderful and informative post on how tree's create and store carbon dioxide, I really am enjoying these posts please keep them coming

Great info on the photosynthesise and carbon dioxide. Thank you, great article!

Hope this could inspire people not to cut down the trees but instead will encourge them to protect and contribute in their growth, for better global climate. This scientific research will help to design the industrial area too.

Loved this, Thank you.

Very interesting, Further should be conducted, I would personally like to see more.

How can you have a mass of Co2 higher than the mass of the actual tree? :s

Vera Barbosa

Each tonne of carbon equals to approximately 3.67 tonnes of CO2 taken out from the atmosphere. The reason you have a mass of CO2 absorbed by a tree which is higher than the mass of the actual tree is that the CO2 molecule is not made of just carbon; it also contains two oxygens for each carbon; and only the carbon part of CO2 is absorbed and therefore counted as part of the tree biomass. I hope this answers your question.

Then why does the Kyoto Protocol encourage countries to cutdown natural forest and replant them? I mean, take a look at Guyana. They cannot participate in carbon credit scheme because their forests are not replanted. Shouldn't it be opposite way around? What I heard is when a tree breaks down, stored carbon escapes, making the Protocol a bit hypocritical :(

Vera Barbosa

Thank you for your input Yuri. Here is the link to a review paper which discusses the issues related to forest management and C sequestration. I hope it will help to answer your question. http://cabiblog.typepad.com/hand_picked/files/PAV2017.pdf
