Many animal species have been freely translocated around the world as part of the exotic pet trade. Globalisation has been one of the main contributing factors leading to human movement and trade of diversified species from continent to continent. To date, more than 1000 reptiles are sold as pets worldwide. These include species such as the Burmese python Python bivittatus, green iguana Iguana iguana and and red-eared slider Trachemys scripta that have become invasive as a result of pet release or as escapees. Impacts associated with these species include transmission of zoonotic diseases, negatively affect biodiversity through completion, predation and/or hybridisation.
Online trade and physical pet stores are two of the pathways by which many reptile species are traded in different countries. This has resulted in difficulties in tracking or monitoring species sold across diversified platforms. Poor monitoring of the pet trade often leads to establishment of several alien species which may be associated with economic and environmental impacts.
South Africa is one of the countries that has trade in reptilian species. Some of the South African native species are illegally exported as pets to various countries. The sale of native species may lead to local extinction, while the sale of alien species potentially leads to invasions. Relatively little monitoring of the reptilian pet trade has been conducted here. As part of the proposed study physical pet stores and online trade will be monitored to determine the trade volume of both native and alien reptile species in South Africa.
