Sampling Strategies
Using the the virtual tree tutorial, I attempted the three sampling techniques systematic, random, and haphazard using the Mohn Mill community. Using the random y-value selected of y=5, so the…

Blog Post 4: Sampling Strategies
In the virtual forest tutorial I used three sampling techniques (systematic, random, and subjective) using area-based methods. When using a systematic technique, I was able to sample five species of…
Post 4 – Sampling Strategies
The three sampling methods I used in the virtual forests sampling theory exercise were simple random, random and haphazard sampling. The time results are as follows: Simple: 12 hours, 41…

In the virtual forest sampling theory exercise, the three sampling strategies used include systematic, haphazard and random. I used distance along with an area-based method for my sampling techniques. The…
Sampling Strategies from Virtual Forest Tutorial
From the virtual forest tutorial, the data shows that the most efficient sampling method was the random sampling based on distance, providing an estimated time of 12 hours and 5…
Comparing Three Sampling Strategies in the Snyder-Middleswarth Natural Area
This was a highly relevant exercise to a self-paced online ecology class, and I am thankful that Bucknell University produced it. Note that I sampled 25 plots, not 24 as…

Sampling Strategies Isaac Hudson Foy
The first technique, sampling along a topographic gradient had the fastest sampling time, but only by an estimated 3 minutes compared to the second sampling method. Therefore, the two first…
