REFLECTIONS

My study looks at the relationship between water availability along a moisture gradient and its role in influencing vegetation spatial organization patterns within my study area Baldry Creek Park. Another blind observer and I, collected 30 (15 per category) independent replicates from a possible 960 replicates (160 lots each 6 m2), using a 1m x1m quadrat within a certain lot. Each lot has the possibility to be sampled 6 times I.e., with 6 quadrats. This is how I determined that 960 independent replicates are possible. Sample collection was done over 3 days, with 5 replicates per day, and all samples were collected at the same time of day, 12:00 PM CST.  To measure my predictor variable, I also recorded whether the lot I am sampling is in either the high or low water accessibility (L= > 10 m/H= <10 m). I determined my moisture gradient on the observation made that some soil areas are damper than others. Using a tape measure to measure, I determined resource heterogeneity (either high or low access to water) by measuring the furthest distance from the pond at which point the soil was no longer damp, which was approx. 10m. (moisture gradient; damp, <10m from pond, dry, >10m from pond). After my first day of sample collection, I decided it would be more time efficient to have another observer help me collect data. Otherwise, I had no difficulty implementing my study design other than attempting to tackle time constraints. I have a newfound deep respect for ecologists and ecological theory development and subsequent research. This has been one of the most challenging courses I have done but it was a wonderful experience overall.
