The truth is if you want to record both humanic soundscape and the nature sounds, the only way is to record them seprately and then mix them together, so that you can make the amplitude of nature part larger, and then these two parts will be field-recording balance. Since humanic sound (especially those really huge and patternic one) would make nature sound litereally "unsound" by microphone's ears.
