Evaluating sampling intensity

Hi All:
I have 7 years of data for leaf litter mass in 13 stands, and I am writing a paper to advise other researchers on how sampling intensity affects uncertainty in estimates of litter mass.  For the number of years sampled, I randomly sampled 10000 times with replacement(bootstrapping). Is this a correct method?

Re: Evaluating sampling intensity

If you have only 7 years of data it might be equivalent to use an analytical method to weight the liklihood of each combination.

That being said, I would worry that 7 data points is not sufficient to define your distribution and it might be that you need more data.
