Hi Merav Take a look at systematic sampling design for plots. Example links
http://www.fao.org/forestry/11649/en/ and assessment of uncertainty in spatially systematic sampling by Heikkinen (Finnish Forest Research Institute). http://www.metla.fi/pp/JuHe/pub/sluumea05.pdf Also do a search under "bootstrapping" for other ideas for measuring uncertainty. Hope this helps.

Most of the literature I've found deals with point sampling, but I'm interested in sampling plots (each of my plots is 25 x 25 m). Are you aware of a suitable simple protocol? All I was able to find in the literature was either point sampling or papers that didn't specify their exact method. Please let me know if you have some information - either a protocol or a good advice. Thanks!
