Raw annual and perennial abundance data

This data set contains annual abundances for all sites and all years (2008-2012) as well as perennial heights in cms (2009-2012) and perennial ground covers as percentages (2008-2012). It also contains a column called "relationship" which shows the type of relationship found between annual abundances and perennial heights (one of positive, negative or quadratic) according to the method described in the paper. This data was used to produce figures 4, 5, 6, B2 and B4.
