Dear Colleagues,
Few days ago I asked the following question on how to integrate
ecological evaluation into the regular forest inventories. So far I have
received some very helpful replies. However, all replies referred me to
works done by US Forest Services or other US organizations. Does anyone have
information on similar works conducted in a different country?
Thank you very much!
