Since I found several discrepancies, I assumed the species lists were not up to date, i.e. at least last year's data was not included. For example, the chart for blocks with 6-20 species includes 67A6 with 12 species, but the list of species includes only 3. Similarly, for 67B6 the chart indicates 12 species, but only 9 are listed. Is there an explanation for this? I plan to try to help out with a few of these blocks, but I would like to know if I am really contributing.
