Annual CITES export quotas for C. gracilis between 2000 and 2013 ranged from 3,000-10,400 (7,079 average) wild collected individuals and 20-12,177 (6449 average) captive bred, captive born, or ranched individuals per year across their native range (CITES 2013). Between 1977 and 2011 (2012 and 2013 trade data is incomplete or unavailable) a total of 95,853 live individuals were exported from across the native range of this species for the pet trade (total of all undeclared, captive breeding, personal and commercial exports), of which 37,075 were reported as either captive bred, captive born, or ranched (UNEP-WCMC 2013). All 37,075 individuals exported as either captive bred, captive born, or ranched were exported from 1996 to 2011 and reached a peak of 5297 individuals exported in 2003 (UNEP-WCMC 2013). Annual exports of this species peaked in 2003 with 7,328 individuals exported and from 2002 through 2011 averaged 4,906 individuals exported (UNEP-WCMC 2013). Most of these exports stemmed from Togo (33,969 total individuals from 1977 through 2011), Ghana (24,764 total individuals from 1977 through 2011) and Benin (19,990 total individuals from 1977 through 2011) (UNEP-WCMC 2013). From east Africa, exports of C. gracilis have been reported from Kenya (4,546 individuals from 1997 through 1981), Tanzania (9,974 individuals) and Uganda (1,063 individuals) (UNEP-WCMC 2013).
