Description
A .csv database that lists the Atlas Quad (i.e., Topo) shared by both Atlas 1 and Atlas 2 and includes all species detected by both as columns (alpha codes). Possible or above breeding codes were used as evidence of breeding in a quad and differences between the two atlases were categorized. 1 == a decrease (present in Atlas 1 and absent in Atlas 2), 2 == increase (absent in Atlas 1 and present in Atlas 2), 3 == no change (present in both). 4 == possible increase (absent in Atlas 1 though survey effort was rated as below 'minimal' and present in Atlas 2), 0 = no data from either Atlas.
