The Colombian slider turtle (Trachemys callirostris callirostris) is a subspecies under a high level of exploitation in Colombia, of which nothing is known about its reproduction in highly disturbed areas with low hunting pressure. We studied some reproductive traits in three different aquatic environments created by coal mining in the Cerrejon mine, La Guajira department, during part of the reproductive season in 2011 (between March and June). We recorded hatching success (56.9 %) only in the stabilization ponds. In the mining reservoir, the 100 % predation rate was the factor limiting hatching success. The recommended option there is protect the nests from the main predator (Procyon cancrivorus) and the relocation of some of them for ex-situ incubation. The low level of nesting recorded in the rehabilitated area may have been the result of extraction of adult females, but also could be due to habitat limiting factors influencing the growth of individuals, or by demographic factors. Size variables measured for clutches, eggs, and hatchlings at the three study sites, showed the possibility that nesting females are larger than those of other populations subjected to hunting in Colombia. However, to determine the extent of geographic variation when compared to other populations it will be necessary to examine temporal variation in reproductive traits of the Cerrejon population.
