Introduction

RhODIS is a pro6ect that ?as initiated .) the eterinar)-enetics @a.orator) of the niversit) of /retoria in order to help ?ith the pli'ht of the

rhinos" $he eterinar) -enetics @a.orator) is collectin' DNA samples of rhinos across thecountr) to create a data.ase usin' the unique DNA profile of individual rhinos"$he 'oal is for all rhinos to .e on the s)stem" $his ?ill deter poachers and assist inforensic prosecutions"

RhODIS?as first used in a rhino poachin' case in ,*!* and resulted in a ietnameseciti4en .ein' sentenced to !* )ears imprisonment for havin' rhinoceros horns frompoached rhinos in his .a''a'e ?hen he ?as apprehended at OR $ham.o InternationalAirport" South African National /ars have partnered ?ith RhODIS since ,*!*and in association ?ith the Forensics Science @a.orator) of the South African /oliceServices have pla)ed a e) role in the development and implementation of the RhODIS Bit

for sample collection"

$he South African Department of Cnvironmental Affairs introduced amendments to thenorms and standards for sample collection and identification of live and poached rhinosunder the National Cnvironmental 9ana'ement: ;iodiversit) Act !* of ,**1 ?hich requiresthat samples are collected from all poached rhinos and other rhinos that are immo.ili4edor die usin' RhODISits ?hich then have to .e su.mitted to the eterinar) [email protected]) for inclusion on the RhODISdata.ase" A num.er of other .odies includin' theSouth African National /ars (onorar) Ran'ers the 0orld 0ildlife Fund corporates andindividuals have donated funds to support the development and implementation ofRhODIS" eRhODIS has .een developed as an ad6unct for RhODISto aid in thecollection of samples and information relevant to the RhODISpro6ect and Samsun' is thee=clusive technolo') partner associated ?ith this development"
