Demographic Survey of Gopherus polyphemus (Gopher Tortoise) at the Abacoa Greenway
- Date Issued:
- 2014
- Summary:
- The Abacoa Greenway reserve is a 105 ha preserve in Jupiter, Florida. We investigated the demographics of the gopher tortoise population and their burrow distributions in a 9 ha portion of the greenway (Range VIa) used for the relocation of gopher tortoises. Range VIa currently houses at least 90 tortoises. According to state guidelines this reserve is considered to be a “support population” with ≤250 individuals living in an area ≤100 ha. We found that the tortoises in the reserve are showing signs of maturity at a younger age (7-10 years) and a larger size (25-35 cm carapace length) compared to more northern populations. We hypothesize that this is due to the latitudinal climate effects and warm winters allowing year-round foraging. For the gopher tortoise burrow distribution, we found that many tortoises are creating new burrows on the periphery due to the overgrowth of the vegetation in the interior of the reserve and a reduction mowing is needed.
