Sampling Effort

Maine maps for confirmed historic species records (before 1973), all confirmed species records (historic to present), and recently confirmed species records (1973-2016 only).  In each case, confirmed indicates the presence of a species based on either specimen or image vouchers (updated April 2015).   Note: clicking on the recent map will link to a higher resolution image that includes township names.
