OnthenightofWednesday,14May2014,27TexasTech students tossed and turned in their beds, desper-
ate for sleep, imagining what the next three weeks would bring.Mostofushadspentmonthspreparingforthetripby learning about the country, raising money, and filling out travelpaperwork.Forgetstudyingforfinals,weweremoreconcerned with packing! Leaving something behind was sim-ply not an option, but getting everything to fit into a single suitcasewascertainlyachallenge.Herpetologywasnotthefocus for this trip, but we were excited about all the wildlife weweregoingtosee.Wepreparedourselveswithaseriesoffieldguides.AlthoughonefrogguidespecifictoZimbabwe(Lambiris1989)wastootechnicalforourpurposes,wegen-erallyfoundtheSouthAfricansnake(Marais2004)andfrogguides(duPreezandCarruthers2009),whichhaveindi-vidual records and maps for all species, more useful than the “reptile”guideforlizards,turtles,andcrocodilians(AlexanderandMarais2007).Consequently,wewereunableinmanyinstancestoidentifythereptilesweencounteredtospecies. After considerable preparation, we finally were ready to embarkononeofthegreatestadventuresofourlives.Afterthree airports, one lengthy layover, and roughly two days of travel, we were excited to be on solid ground again — and our
three-weekjourneyacrossSouthAfricaandZimbabwebegan(Fig.1).AswewaitedintheSouthAfricancustomsline,mostof us tried to get on our phones to connect with friends and family,buttonoavail.Wecertainlyweren’tinTexasanymore.

Our first stopwas theCradleofHumankindWorldHeritage Site in Maropeng, where we learned about our humanancestorsandtheevolutionofotherspecies(Fig.2).We also explored the Sterkfontein caves, where we viewed currentarchaeologicaldigsitesandthesitewhere“Mrs.Ples”(Australopithecus africanus)wasfound.Theviewsurroundingthe caves still might be very close to what some of our earliest ancestorsexperiencedwhentheyroamedthearea(Fig.3).

Our trip was during theNorth American summer,whichmeantitwaswinterinSouthAfrica.Wehadhopedtoseesomechameleons(eightgeneraandover160speciesareknownfromAfrica;AlexanderandMarais2007);theyarecommonintheregionandverydifferentfromtheliz-ardswithwhichwearefamiliar.Althoughweweretoldaboutthem wherever we went and saw images of chameleons in localart(Fig.4),wesawnotoneindividualduringthistrip. We departed Kenjara Lodge early the next day and spent a memorable eight hours first passing through South African customs in order to leave the country and then waiting in another long line until we were finally granted permission to enterZimbabwe(we suggest taking a plane into Bulawayo for amuchfasterandsmootherentry).Afterourexhaustingdayattheborder,anadditionaldrivetookustoLimpopo.Thedelicious dinner served by the Nottingham Fishing Retreat staff and a night spent admiring the stars were the perfect endingtoourfifteen-hoursoftraveling.

five days we spent in Hwange, we saw the gamut of African species,includingCommonHippopotamus(Hippopotamus amphibious;Fig.27),AfricanBuffalo(Syncerus caffer),GreyHornbill (Tockus nasutus), Black-backed Jackal (Canis mesomelas),thesnake-eatingSecretaryBird(Sagittarius ser-pentarius;Fig.28),Black-facedImpala(Aepyceros melampus),andzebra.Cheetahs(Acinonyx jubatus)alsooccurinthearea,butwesawnoneduringourtrip. Easiest of the species to find is the icon of Hwange NationalPark,theAfricanElephant(Loxodonta africana;Fig.29).Astaggering40,000oftheminhabitthe14,651-km2 park (5,700sqmi),exceedingthecarryingcapacitybysome25,000.Intheearly1930’s,oneoftheparkstaffbeganbuildingwaterpumps in Hwange with hopes of increasing the wildlife popu-lation.Bythen,developmentinsurroundingareashadpre-vented the traditional migration of elephants away from the park, which lacks permanent water sources during the dry season.Withtheadditionofthepumps,theelephantpopula-
tion skyrocketed, detrimentally impacting the flora and other fauna.Theplantlife,includingtheAcaciaTrees,isseverelyovergrazed,andthelandsurroundingwaterholescavesinwardbeneaththeimmenseweightoftheelephantherds.Otherspe-cies are unable to access the limited water sources when ele-phants are present, and eventually disappear as they are unable tocompete.Thesmallerspeciesarenottheonlyonessuffer-ing, however; whenever periodic droughts occur, elephants die inlargenumbers.Sometimes,theelephantscrossthepark’sborder fences and consume entire fields of crops grown by localresidents.Thisdirectlyincreasesthelocals’propensitytopoachanddisregardtheelephants’roleasaprimarysourceoftourismandindirectsourceofincome. We discussed several methods that could help restore Hwangetoitsnaturalcarryingcapacity.However,noneofthem seem to be socially acceptable, physically possible, or economicallyfeasible.Cullingtheelephantsisunacceptabletoawesternsocietythatbelieveselephantsareendangered(asmanypopulationsare).Removingthewatersourceswillleadtotheslowandhorrendousdeathofmanyanimals.Localbudgets for park maintenance are minimal, and trade in ivory, which could fund much management, is banned by interna-tionaltreaty(CITES,theConventionontheInternationalTradeinEndangeredSpecies).Finally,theoptionofrelocat-ingelephantswouldrequireanelephant-freeareaaslargeandrichinbiodiversityasHwange,whichissimplynotavailable.ThisleavesZimbabwewithtourismandagricultureasitstwoprimary legs for development, and few options for managing theover-populatedelephantherd.
