Thank you for your question. The captive habitat of this species can be either very simple or elaborate. There are a few simple requirements that should be met however. Adults need to have a water area that is 2 feet deep and stays under 70 degrees. If the correct water temp isn’t maintained, these turtles can overheat. By far, the best enclosure for a wood turtle is outdoors. A single adult would do fine in a 5 ft x 5 ft enclosure with a pond of at least 2 feet in depth and about half the size of the pen. Multiple adults would do fine with an extra 4 sq. feet of space per adult. If you absolutely must house adults indoors, nothing less than a small kiddy pool should be used. A 50 gallon Rubbermaid is simply too small for an adult wood turtle. With housing indoors, it should only be temporary so that you don’t compromise the health of your turtle. Hatchlings and juvenile wood turtles can be housed indoors until they get to about 5 inches in Straight Carapace Length. After that time, they should be moved to an outdoor enclosure.
