  1. The sites are sub-divided into four categories (arable, plantations, perceived areas of high species richness (HighSpcRich), and natural). The natural sites were stratified across specific levels of succession (early, mid, and late), soil moisture (wet, moist, and dry) and soil fertility (rich and poor), while this was not the case for the other classes of sites. The number of sites within each of the 25 classes is given
