The technique with the fastest sampling time was systemic (sampling along a gradient).

Systemic: 12hr 7m

Random: 12hr 40m

Haphazard: 13hr 1m

% Error respectively

Eastern Hemlock, Sweet Birch, Striped Maple, White Pine.

Systemic: 17.9%, 46.8%, 28.6%, 197.6%

Random: 14.0%, 68.1%, 100%, 98.8%

Haphazard: 2.15%, 2.13%, 54.3%, 42.9%

Accuracy decreases with decreasing species abundance. As seen above, the first two numbers represent common species accuracy whereas the second two numbers represent rare species accuracy.

Based on the data I collected, haphazard seems to be the most accurate. This was likely due to my selection of quadrants to sample. I chose quadrants that were spread out and sampled all regions of the area. Haphazard could have decreased in accuracy if I chose to select quadrants that did not represent the whole area.
