Mohan Mill area is the community being observed in the following. The random sampling technique took 13 hours and 9 minutes. The systematic sampling technique took 12 hours and 47 minutes. The haphazard sampling technique took 13 hours and 27 minutes.
Systematic Percent errors:
Red Maple (Common species): 2.86%
Eastern Hemlock (Common species): 2.38%
Yellow Birch (Rare species): 3.2%
Random Percent errors:
Red Maple (Common species): 1.82%
Eastern Hemlock (Common species): 3.12%
Yellow Birch (Rare species): 0.8%
Haphazard Percent errors:
Red Maple (Common species): 4.84%
Eastern Hemlock (Common species): 3.8%
Yellow Birch (Rare species): 0.6%
Total Quadrants sampled = 18
Area sampled = 1800 m^2.
Total species sampled for systematic technique = 8, species sampled for random technique = 16 and species sampled for haphazard technique = 12.
For common species each technique gave similar errors.
I am always surprised how close the sampling times are. The errors for the rare species seem too small. They are always very large which is one of the take homes from this assignment – rare species are hard to study and you need a lot of samples!
