I’ve decided to study Typha latifolia or Broad Leaf Cattail. The cattails are seen along the river’s edge and only seem to be found in marsh areas or in lower areas of the landscape. I will observe the cattail where the lake enters the river, along the river (further downstream) and off shore away from the river and lake.
Hypothesis: Broad Leaf Cattail will only be found in marsh areas (river or lake side) and lowers areas in the landscape because they require moisture to survive.
Prediction: the lower the landscape and the closer to water, the greater abundance of Broad Leaf Cattail.
Response Variable: cattail abundance (categorical).
Explanatory Variable: lower landscape and water (continuous).
