umphakathi Omkhulu Owenzeka Ngokwemvelo Weziqhingi
I-Vredefort Dome itholakala emphakathinI omkhulu owenzeka ngokwemvelo weziqhingi, lapho kuqhamuka phakathi kwendawo ephakeme yeHighveld ne-Transvaal. Uhlobo lwotshani luvame ukubizwa ngokuthi yi-Bankenveld, kodwa ifa eliyingqayizivele lemvelo le ndawo liphumela ekuhlukeni okuningi okungavamile. Isibonelo, izinhlobo ze-hlathi ezivame ukutholakala ngamakhulu amakhilomitha ukuya enyakatho zikhona, ezifana ne-Bush Willow, i-Red Ivory ne-Tree Ferns. Isihlahla somfula ngasemaphethelweni aseVaal sinezela nasezinhlobonhlobo zemvelo.Emagqumeni nasezinhlakeni zeDome, izinhlobo ezihlukahlukene ze-microhabitates, microclimates kanye nezinhlobo zenhlabathi zenza imiphakathi eminingi yezitshalo iphumelele. Uhlu oluphelele lwezitshalo alukapheli, kodwa kunenani lezilimo eziyi-99 ezikhona kule ndawo. Izihlahla ze-Olive zasendle zivame kakhulu futhi izitshalo ezinkulu zemvelo zalesi sifo (i-Olea europaea subsp. Africana) itholakala kunduduma ngaphandle kweParys. Izinhlobo zezihlahla ezinameva nezihlahlana ezihlezi ziluhlaza nazo zande kakhulu.
Izinhlobo Zezitshalo Ezingejwayelekile
Izinhlobo Zezitshalo ezingejwayelekile zinkinga eDome. Izihlahla ze-gum zixubha emgodini ovundile we-Vaal.izihlahla ezivela emazweni angaphandle ezifana nePoplar, amaWill Willows kanye izinhlobo ezahlukene zePrickly Pear nazo zixosha izimila zomdabu. I-hyacinths yamanzi iyinkinga ethile, njengoba ikhula kakhulu eMfuleni weVaal futhi ivimbele amanzi. Kuzofanele kwenziwe umsebenzi omningi ukuze ubuyisele indawo endaweni yobuhle bayo bomdabu.kunezinhlobo eziningi zezinyoni,izinhlobo ezingaphezu kwamakhulu amabili okwakungenza labo abathanda ukubuka izinyoni bejabule.lezi zinhlobo zihlanganisa : ama-cormorants,Indwandwe,ilanda, ama-spoonbills, inqe, ukhozi,unhloyile, ukhozi oluqeqeshiwe ukubamba ezinye izinyoni, umaththebethebeni,Impangele,izinyoni ezincane,izinyoni zohlabathi,isikhova,izitsha zobusuku,ihlolamvula, izinkomonyoni, unongozolo, othandela, ama-barbets, izinyoni ezicosha ukhuni, inkonjane, ama-martin, ukhwezi, izinyoni zelanga, izinyoni zasendle, ababhishobhi, izinyoni zokutshiyoza, izingxoxo nama-tits. I-Inlandsee Pan, eduze neVredefort, iyindawo ebalulekile yomhlangano yezinyoni ezifudukayo.
Izinhlobo Zemininingo Ebomvu
Nakuba i-Dome yayisetjenziswa njengendlu izilwane ezinkulu ezinhlanu, zonke izilwane ezinengi zazingelwa njengombana abalimi bathatha indawo. Noma kunjalo, kusekhona izinhlobo ezingamashumi amahlanu zezilwane ezincelisayo ezincane, kuhlanganise “izinhlobo zemininingo ebomvu” eziyisihiyagalombili. Ingwe, i-rooikat, impisi, ikhanka, unogwaja kanye nempofu zikhona, futhi amapulazi amaningi emidlalo kanye nezinqolobane zemvelo njengamanje zivuselela izilwane zasendle.Vredefort nayo inomthelela ogcwele wezilwane ezinwabuzelayo ezihamba ngokuthula, izinyoka, ama-scorpions nezinambuzane. Kukhona ingcebo ephawulekayo yezinhlobo zemvemvane, ngakho-ke uma ungumuntu oyisiphukuphuku, lokhu kuyindawo yakho! Eqinisweni, kuthiwa kunezinhlobo eziningi zemvemvane eDome kunazo zonke ezaseBritain Isles. Ngaphandle koMfula iVaal, iDome igcinwa ichithelwa yimvula enhle ephakathi kuka-625 mm, i-500m yayo ewela ezinyangeni zasehlobo.Ukoma kwamanzi akuvamile. Ehlobo, izinga lokushisa liyashisa, izinga kushisa eliphakeme elingamashumi amathathu kuya kushumi nanhlanu emini. Izinsuku zasebusika ziyashisa (cishe ngeshumi nasiyagalombili) kodwa ubusuku bungabanda kakhulu.
