Here is my proposed graph from the data I collected:
I decided to show each tree species at each exposure level rather than creating three graphs of each species. I attempted several formats before concluding that this was the most representable option.
These results slightly follow the predicted pattern, Quercus garryana most abundant in low exposure regions, and Pseudotsuga menziesii present in the highest exposure level. The pattern varies off track slightly, showing that my results may require further interpretation. The Quercus garryana trend does show significantly low values at the highest exposure level. Pseudotsuga menziesii values vary with a parabola trend. The Arbutus menziesii data appear to demonstrate an unexpected trend – low values in extreme high and extreme low exposure levels. This result may indicate that Arbutus menziesii require very specific conditions for growth. Arbutus menziesii values are also relatively low, showing that in both extremes it is not the dominant species.
Further exploration could include analyzing the substrate type and soil cover in each area, to determine if the trends follow the same pattern.
