If you have the area of certain trees for successive ten years, what is the best analysis to calculate the growth rate for this group? And if you have the weather data for the area, what are the analysis you use?
Assuming you have inventoried data for all ten years, you can calculate biomass growth which these days it is an interesting subject for doing research. You can calculate relative yield and maybe, growth efficiency as well.
You may use permanent sample plot (psp) to take mensurational data. After getting mensuration data, you may calculate tree volume by means of calculating biomass vol. (cu. m/ ha/ yr. If you try to correlate between meteorological data with mensuration data, you may measure Climate Vegetation Productivity Index (CVPI). Though age old method (Paterson 1956), CVPI gives us the comparison approach that how much the growth of forest in that study region could get best productivity with optimum soilfactors.
I agree with Md, Siddiqur Rahman, other is to make a lodgepole annalysis to correlate age with grow, other is to determine the site index.
