Uncertainty between trees with different diametric classes

Hello everyone!!
 
Maybe someone can give me a clue!!
I am working in order to obtain the biomass and uncertainty of a forest inventory in Peru.  The plots has not the same area for the bigger trees (dbh>= 30) and the smallest (dbh <30cm).  Actually I create my function to obtain the biomass and uncertainty. But now I would like to sum both values the big and small trees. but I am not sure its going to be ok, to sum just as a simple way. I imagine I must weight the values, in order to do not make an statistical error.  That any one can give and avise how i must weight de values, could i do it by basal area or number of trees by plot? I would appreciate it any comment!!
 
Best regards

Re: Uncertainty between trees with different diametric classes

If you calculate the biomass and uncertainty per unit area (you divide by the area measured), then you should be able to sum the two classes.  Am I missing something?

This can be also a fairly beneficial writing that any of us absolutely beloved considering. Possibly not on a daily basis which often experience the likelihood to get a solution.

I am so happy to read this. This is the kind of manual that needs to be given and not the random misinformation that’s at the other blogs.

Surprise! Almonds are the most nutritionally dense nut, meaning they offer the highest concentration of nutrients per calorie per ounce. For just 191 calories, a one-ounce serving provides 3.4 grams of fiber (that's about 14 percent of the daily recommended value) and a healthy dose of potassium, calcium, vitamin E, magnesium, and iron. Plus, you can eat them as BUTTER!

Slightly spicy but oh-so-enjoyable, ginger has been used for years as a delicious flavoring and an all-natural remedy for everything from an upset stomach to unwanted inflammation.
