Toward this end, we obtained records of eastern indigo snakes by: (1) searching databases, the literature, and u.s. museum collections; (2) soliciting sightings from qualified individuals via e-mail and questionnaires; and (3) conducting visual-encounter surveys in georgia. in southeastern and south-central georgia, we documented 379 recent (2001−2012) records from 29 counties and from 26 public or conservation lands (≥ 100 ha in area) in 18 counties. in florida, we documented 595 recent (2001−2012) records from 46 counties and from 154 public or conservation lands ≥ 100 ha in area in 44 counties.
