I intend to study the yellow “bunchgrass” which is nearly omnipresent in the field I have been visiting. During my most recent field observations, I found that in troughs, other plants dominated and the bunchgrass was barely present. I observed this is the areas marked in yellow on the map. N.B. Google Maps has apparently not updated this area in a few years.
I would guess that the “bunchgrass” grows better on light slopes and at the top of hills because moisture collects in the low-lying regions, and the plant is better suited to dryer soil.
Hypothesis: The density of yellow “bunchgrass” correlates to location on hills (i.e., peaks, troughs, or slopes).
Prediction: The density will be significantly lower in troughs.
Response variable: density of yellow “bunchgrass”, continuous.
Explanatory variable: location on hill (peak, trough, or slope), categorical.
