I decided to collect data by implementing a systematic sampling strategy using quadrats as the sample unit along a transect. I initially encountered some difficulties in deciding how to quantify plant species presence but resolved to follow the example provided of dividing the quadrat into a grid and counting how many squares each species appeared in the grid.
From the time of my initial observations (spring/summer) to the first data collection (fall) there was a notable change in plant species variation, abundance, and health across all sections of the lawn.
I did not experience any major difficulties with the sampling strategy and will likely carry forward with this method; however, based on the observations of differences in seasonal growing patterns I will likely need to revise my hypothesis.
Sounds like a typical field study, some changes required along the way and there is often something surprising in the data.
