Most species found are red maple and witch hazel and less species found aee white ash and yellow birch. The fastest technique is systemic with 12 hours and 7 minutes but there is no significant difference with other two. The random technique has the highest percentage error for both common and rarest species. When comparing systematic and haphazard, both have the same percentage error for rarest species but for common species, systemic one is reliable with approximately 5.2% error. The accuracy definitely changes with species abundance, common species measurements are way more accurate with this technique and rarest species are not accurate at all. The systemic sampling strategy is the most accurate and less time-consuming.
