The most obvious factor revealed by the first two graphs is the effect of more intensified and comprehensive coverage in the years since Atlas 2000 recording. At the left-hand side of the graph, there are many fewer tetrads with very low counts, while much of the rest of the graph shows a small to significant increase in species recorded across almost all the range of species tallies. The overlaid graph makes this a little clearer.
Across the whole county, there is little to suggest a general decline in axiophyte distribution at this resolution.
