For my initial field data collection, I conducted six replicate samples. These samples were distributed as follows: two samples from each of the three main areas identified within the site.
One significant challenge I encountered was the lack of a structured sampling plan. In my enthusiasm to gather data, I visited the site and began selecting areas based on what seemed appropriate at the moment. This “impromptu” method I chose provided valuable insights but from my perspective I think there is still bias from what I think “fits” as a sample in this study. To address this and in addition to it, my next steps will be to include the other two types of systemic and haphazard type of sampling. Additionally, I plan to introduce another criterion for my observational evaluation. Besides assessing plant health and abundance, I will also evaluate the number of species present in each area.
Despite the initial challenges, my field data collection revealed some interesting patterns. One trend was the impact of human recreational activities on plant health and abundance. Areas near recreational spots showed fewer plants and poorer plant health compared to more secluded areas. This observation aligns with my hypothesis that human activity is a big factor affecting the environmental gradient of the park.
However, this finding also made me think to consider other factors that could be influencing these patterns. For instance, soil compaction, litter, and pollution from recreational activities could be contributing to the observed decline in plant health and abundance.
