What these results show
These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.

Finer identifications
Some Ohio records of this species were identified to a subspecies:
- Trachemys scripta elegansRed-eared slidersubspecies
- Trachemys scripta scriptasubspecies
Every one of these records counts toward the Pond Slider's season above.
Why some records go further than species
Many species vary from place to place. Groups of a species that look or sound a little different, and live in different areas, can be named as subspecies. Observers and experts only identify a record that far when it shows enough detail to tell them apart. Records without that detail count at the species level.
