Die nagenoeg 400 jaar oue geskiedenis van eikebome in Suid-Afrika kan dalk tot \u2019n einde kom en die boomlandskap van dorpe en stede soos Kaapstad, George, Paarl, Stellenbosch en Swellendam vir ewig verander.<\/p>\n\n\n\n
Volgens \u2019n navorsingsartikel wat onlangs in die South African Journal of Botany<\/span> verskyn het, het ekolo\u00eb van die Sentrum vir Indringerbiologie (SIB) in die Universiteit Stellenbosch se Skool vir Klimaatstudie die geskiedenis van die genus Quercus<\/span> in Suid-Afrika nagespoor \u2013 wanneer dit vir die eerste keer hier ingebring is, sy huidige status, asook die faktore wat verantwoordelik is vir die verandering in die verspreiding daarvan oor ons landskappe heen.<\/p>\n\n\n\n Christiaan Gildenhuys, \u2019n nagraadse student in die US se departement plant- en dierkunde en hoofouteur van die artikel, s\u00ea die eerste geskrewe rekord van die steeleik (Quercus robur<\/span>) dateer uit 1656 en is volgens oorlewering deur Jan van Riebeeck self ingebring.<\/p>\n\n\n\n \u201cDosyne ander eikeboomspesies is deur vroe\u00eb Hollandse setlaars en die Britse koloniale regering ingebring.<\/p>\n\n\n\n \u201cDaarna is dit wydverspreid oor die land aangeplant en het sedertdien een van die mees wydverspreide en herkende boomgenera in hedendaagse Suid-Afrika geword,\u201d verduidelik hy.<\/p>\n\n\n\n Maar nou is die spesie in \u2019n doodloop\u00adstraat.<\/p>\n\n\n\n Gildenhuys het bevind drie eikeboomspesies \u2013 die steeleik, moeraseik, en kurkeik \u2013 het op rivieroewers en in die koppelvlakgebiede waar stad en natuur in Stellenbosch en Kaapstad ontmoet, indringers geword. Tans veroorsaak hierdie eikebome nog nie groot probleme as indringers nie, maar kan moontlik in die toekoms. <\/p>\n\n\n\n Terselfdertyd is baie van die spesies (wat die Q. robur<\/span> of steeleik, wat die mees wydverspreid voorkom, insluit) hoogs vatbaar vir siektes en indringerkewers soos die stompkopkewer.<\/p>\n\n\n\n \u201cDit beteken baie van die eeue oue eikebome is nie net in gevaar nie, maar besmette bome sal verwyder moet word om te verhoed dat die besmetting verder versprei,\u201d s\u00ea Gildenhuys.<\/p>\n\n\n\n Prof. Dave Richardson, \u2019n ekoloog by die SIB en mede-outeur van die studie, s\u00ea die storie van eikebome in Suid-Afrika is \u2019n klassieke voorbeeld van hoe globale verandering vinnig besig is om die rolle van, en perspektiewe oor, spesies in stedelike gebiede te verander.<\/p>\n\n\n\n \u201cOns moet aanvaar dat die potensi\u00eble impak van die stompkopkewer die speelveld gaan verander.<\/p>\n\n\n\n \u201cDie boomlandskap van baie dorpe in Suid-Afrika gaan as gevolg van hierdie indringing nogal radikaal verander. Grondeienaars en owerhede wat besluit om besmette Q. Robur<\/span>-bome met minder kwesbare boomspesies te vervang, moet ook die potensi\u00eble negatiewe invloed van d\u00e1\u00e1rdie spesies oorweeg,\u201d verduidelik hy.<\/p>\n\n\n\n Die ideaal sou wees om die besmette bome te vervang met inheemse bome wat minder vatbaar vir peste en siektes soos die stompneuskewer is. <\/p>\n\n\n\n Hy waarsku egter dat mense se verknogtheid aan hul strate met eikebome vervangingspogings in die wiele kan ry en konflik tussen bestuur en belanghebbendes kan veroorsaak.<\/p>\n\n\n\n Prof. Guy Midgley, waarnemende direkteur van die Skool vir Klimaatstudie, s\u00ea die bome lewer \u2019n lewensnoodsaaklike bydrae om die impak van klimaatsverandering te versag deur die hittestres in stedelike gebiede te verminder. <\/p>\n\n\n\n Aan die ander kant kan die wyse waarop van duisende siek bome ontslae geraak word, \u2019n groot impak op koolstofvrystelling h\u00ea.<\/p>\n\n\n\n Die debat oor die kulturele waarde van eikebome in die algemeen gooi nog vet op die vuur. <\/p>\n\n\n\n In een van die sektore van die Suid-Afrikaanse samelewing word hierdie eeue oue bome as deel van ons kultuurgeskiedenis gevier.<\/p>\n\n\n\n In \u2019n ander sektor word hulle as ongewenste oorblyfsels van \u2019n koloniale verlede beskou.<\/p>\n\n\n\n Interessante historiese feite oor eikebome in Suid-Afrika:.<\/span> 1656: Eerste geskrewe rekord van Q.robur<\/span>-spesie
