Systematic: sampling along a topographic gradient was the fastest with a total time 12 hours and 5 minutes.
Most common species were eastern hemlock and sweet birtch.
Two rarest species were white pine and stripped maple.
Yes, the more abundant species had a lower percentage error. I also had one of the sampling methodologies come back with no striped maple trees which means that the overall sample size was not large enough to capture the entire population and the the number of samples should be increased.
The most accurate was the systematic: sampling along a topographic gradient method.
A bit short and missing some details.
