Comparative abundance of Yorkshire Fog and Common Bent 2001

The comparisons between sections have been made using mean % cover alone (with data taken from all the quadrats sampled, both belt and random).

Percentage frequency has not been used as a measure of abundance in this case, because it is almost universally high and shows little difference in abundance across the site and from one year to another. Changes are therefore better demonstrated using mean % cover as a measure of abundance because it is much more sensitive to variations between sections and over time.
