The Houston Zoo is dedicated to education and conservation. Of the 9 subspecies of giraffes, there are three that have populations less than 1,000 individuals, as estimated by Giraffe Conservation Foundation. These include West African, Rothschild, and Nubian giraffes. Several other species are estimated at having less than 5,000 surviving in the wild, including Thornicroft's giraffe, Kordofan, and reticulated giraffes.
