Random sampling had the fastest estimated sampling time of 12 hours and 25 minutes. The slowest estimated sampling time was systematic taking 12 hours and 38 minutes. Haphazard sampling was in between taking 12 hours and 36 minutes.

Percentage Error respectively (Eastern Hemlock, Sweet Birch, Striped Maple, White Pine):  *note that Eastern Hemlock and Sweet Birch are the two most common species, while the Striped Maple and White Pine are the rarest species

Systematic: 10.7%, 5.5%, n/a (none found), 52%

Random: 20.6%, 8.1%, n/a (none found), n/a (none found)

Haphazard: 5.3%, 11.3%, 42.9%, 1.2%

Based on these results it is hard to determine which strategy is the most accurate since the random sampling did not find any Striped Maple or White Pine and systematic sampling did not find Striped Maple either. For common species, systematic and haphazard sampling were about equally accurate. My results suggest that 24 was not a large enough sample size to capture species in the rare communities thus insufficient in accurately estimating the abundance of these species.
