The organism I am interested in is scentless chamomile (Tripleurospermum perforatum). Scentless chamomile is abundant on top, but is almost absent at the bottom of the pits.
My locations to record are:
1. On top of the mineral soil: Here the scentless chamomile is the most abundant and tall.
2. Mid-way down the slope: There is a steep decline in the abundance of scentless chamomile mid-way between the topsoil and the bottom of the pit.
3. The bottom of the pit: There is almost no scentless chamomile at the bottom of the pits.
I hypothesize that areas with abundant scentless chamomile will not be acidic. The explanatory variable would be pH (continuous) and the response variable would be scentless chamomile abundance (also continuous). I will measure the pH along the gradient to determine where it is high and where it is low and measure the abundance of the scentless chamomile to compare.
