The cave has a healthy variety of fauna, which can be attributed to its low visitation rate and a sustaining food supply which travels down the entrance series. This is especially evident in the upper most level, where bats, mice, salamanders and a number of invertebrates are regularly seen. However, visitors in winter have not noted any quantity of bats in the lower levels, suggesting that the cave is not a significant hybernaculum. In addition to the area near the entrance series, there are several domes and high fissures which may have served as animal traps in the past. Whether the bones are exclusively of a recent nature or are Pleistocene needs to be determined by knowledgeable, trained personnel.
Initial investigation is intended for after the re-survey is completed.
Researchers who desire access to the preserve should submit a brief, written synopsis of their project along with their qualifications to the MAKC board for consideration. Researchers are also required to submit a written report documenting project progress no later than 90 days after approval has been given, and a final report within one year. The MAKC board will designate a preserve management team to oversee the property. The size of this team shall be determined by the board and one team member shall be named as the preserve manager. The preserve manager shall report directly to the MAKC board of directors on all issues concerning the Billy Clay Cave Preserve.
