Sampling Strategies.

Community: Mohn Mill

I chose 3 sampling strategies in the Mohn Mill Area: The distance systematic technique proved to be the most time-efficient, requiring only 12 hours and 35 minutes followed closely by haphazard sampling with 12 hours 37 minutes and then distance random sampling with 12 hours and 43 minutes. The two most common species were Hawthorn, Red Maple .The least common were Yellow Birch and White ash. When sampled using distance systematic Sampling along a topographic gradient the percentage error was 11.1% for Hawthorn, 2.9% for Red Maple, 100% for Yellow Birch and 100% for White ash. When sampled using random sampling the percentage error was 6.7%, 6.1%, 100% and 100% respectively. For haphazard sampling the respective percentage errors were  15%, 8.4%, 100%, 90%. The least common trees had three percentage errors of 100%, where none of the trees were observed using the sample method. Random distance sampling has the lowest percentage error of  53.2% which could indicate random sampling could be a better option in comparison to the other two methods.
