I study the moss growth and use a quadrat I made myself to measure the growth rate of moss in four light conditions: Full Sun, Partially Sunny, Partially Shaded, and Fully Shaded. For each condition, I have 10 replicates, a total of 40 replicates. I apply the Daubenmire method, which classifies percentage cover into six classes. This is a useful method for more precise estimates of moss growth.
I chose systematic sampling as my strategy. I find this sampling strategy most suitable for this project. Based on the tutorial on sampling methods, haphazard and random sampling were not ideal. They had potential for bias or difficulty in applying under my field conditions. Systematic sampling includes consistent intervals in different light conditions, providing reliable data.
The sampling design has worked well so far. I haven’t had any major issues. However, I have noticed some minor ancillary patterns that make me reflect on my hypothesis. For example, I observed slight differences in moss growth within the same light condition. This can be related to small differences in soil texture or humidity levels. These small factors were not part of my initial focus, but they could have a role in the growth patterns.
