Mohn Mill Community and Area-bade Methods
Each sampling method resulted is very similar estimated sampling time with haphazard having the longest sampling time. Systematic was 12.05 hrs, random was 12.08 hrs, and haphazard was 12.27 hrs. For the most common species, systematic sampling had the lowest percent errors compared to the other sampling styles. But, for least common species none of the sampling methods yielded results. So, for a more accurate community structure, I would suggest increasing sample size to increase chances of creating a more accurate community structure and lowering percent errors on less common species.
Systematic Sampling Percent Error:
Most Common:
Red Maple
(383.33-403.7)/403.7×100 = 5.05%
White Oak 6.74%
Least Common:
Yellow Birch 100%
White Ash 100%
Random Sampling Percent Error
Most Common:
Red Maple 12.01%
White Oak: 17.25%
Least Common:
Yellow Birch 100%
White Ash 100%
Haphazard Sampling Percent Error
Most Common:
Red Maple 14.19%
White Oak 6.31%
Least Common:
Yellow Birch 100%
White Ash 100%
