Comments:
From Appendix C, data columns are historical high count, high count since 2000, and most recent count. Since minimum count was not stated, I entered the minimum from these columns though it might not be the actual minimum across the span of years reported. Also, there is no detail on years that were excluded from surveying so range of survey years may be inaccurate. Breeding was not confirmed but may have been in the past.
