Wake wazibuza ukuthi obani amagama ezihlahla ezihlala eSavana? Lezi zitshalo ziyamangalisa ngempela, njengoba zihlala ezindaweni lapho imvula iphansi kakhulu kangangoba kaningi ayinakho okunye engakwenza ngaphandle kokuhlala ingenamaqabunga phakathi nesikhathi sonyaka esomile. Abanye baze bathathe nezinyathelo ezinqala ngokwedlulele: bayeke ukondla igatsha labo elilodwa noma amaningi ngenhloso eyodwa yokonga amanzi.
Njengoba isimo sezulu kule ndawo siphawuleka kakhulu, ukukhula kwezihlahla ze-savanna akuwona umsebenzi olula ngaso sonke isikhathi, ngoba zizwela kakhulu ekuniseleni ngokweqile kanye naseqhweni. Kepha lokho akusho ukuthi asikwazi ukuwajabulela ezithombeni, yize kusuka lapha ngikukhuthaza ukuthi, uma unethuba, unganqikazi ukubabona bevakashela izindawo abahlala kuzo.
I-Acacia tortilis

La I-Acacia tortilis, noma i-acacia eyisicaba, yisihlahla esijwayelekile esinqunyiwe esivela ezithombeni eziningi ze-savannah yase-Afrika. Umqhele wayo yi-parasol, eyakhiwe ngamagatsha amaningi lapho kuhluma khona amaqabunga e-bipinnate. Kuyabheda, ikakhulukazi lapho isencane, ukuzivikela ezilwaneni eziyingozi. Ingakhula ize ifike kumamitha angama-14 ukuphakama.
Ekulimeni kuyisitshalo esidinga ilanga, nomhlaba odonsa amanzi kahle. Kepha ngeshwa ayisekeli isithwathwa.
I-Adansonia digitata

Umboko wayo ungaba mkhulu kakhulu; empeleni, ukuzungeza kwayo kungadlula amamitha angama-40, futhi finyelela kumamitha angama-25 ukuphakama. Umqhele unamagatsha amakhulu, futhi amaqabunga aluhlaza nezimbali ezinkulu ezimhlophe kuhluma kuwo.
Ukuyihlakulela, futhi uphumelele ngayo, kuhilela ukuyazi kahle. Imbewu yayo iqhuma kahle uma igcinwa amahora angama-24 kwi-thermos enamanzi ashisayo (cishe u-40ºC), kepha i-substrate kumele ibe nezimbotshana kakhulu ukuze izimpande zayo zikhule kahle. Ngalesi sizathu, kuyalulekwa ukuthi ube nayo esihlathini ngokwesibonelo, bese uyinisela ngezikhathi ezithile.
Yebo, angikwazi ukubekezelela amakhazaNgakho-ke uma izinga lokushisa lehla ngaphansi kuka-10ºC endaweni yakho, uzodinga ukuvikelwa.
I-Albizia procera

La I-Albizia procera kungumuthi onqabile okhula e-Asia. Ifinyelela ukuphakama kwamamitha ayi-25, futhi amaqabunga awo anemicikilisho emincane, enamapheshana acijile esikhumba. Ikhiqiza izimbali nezithelo ezimhlophe ngokuphuzi (imidumba) kuze kufike kumasentimitha ayi-15 ubude kuze kube ngamasentimitha angu-2,5 ububanzi.
Kuyisitshalo esihle esingakhula ezifundeni lapho kuna imvula encane, inqobo nje uma umhlaba udonsa amanzi kahle. Ixhasa amakhaza alinganiselayo aze afike ku -7ºC.
UFicus sycomorus

Ikhiqiza amakhiwane adliwayo angaba ngamasentimitha angu-2-3 ububanzi.
Sihlahla esihle esikwazi ukumelana namakhaza abanda futhi abuthakathaka aze afike ku -1ºC.. Kepha khumbula ukuthi izimpande zawo zidinga isikhala esiningi ukuze isitshalo sibonakale sihle.
IHaloxylon ammodendron

El IHaloxylon ammodendron, edume kakhulu ngokuthi i-saxaúl noma i-saksaúl, isihlahla noma isihlahla esincane esikhona e-Asia Ephakathi, esenabela ogwadule lwaseGobi. Ifinyelela ebangeni eliphakathi kwamamitha ama-2 no-10. Amaqabunga mancane kakhulu, empeleni awamane nje abe yizikali ezimise okwe-cusp.
Kubhekwa njengenhlobo esengozini yokuqothulwa, ngoba ngonyaka ka-2008, ngesikhathi senkinga yamandla amandla i-Central Africa yabhekana nayo, kwasikwa izibonelo eziningi ukuze kusetshenziswe izinkuni zazo.
IPistacia Vera

La IPistacia Vera, noma i-pistachio, isihlahla esinqumayo esidabuka entshonalanga ye-Asia lokho ifinyelela ubude obuphakathi kwamamitha ayi-5 no-7. Amaqabunga aso ayimpintshi, futhi ahluma esihlokweni esakhiwe ngamagatsha amaningi. Izithelo zingama-drupes angaba ngu-2-2,5cm, futhi omile.
Kuyisitshalo esifanelekile se- zikhula ezindaweni ezishisayo nezomile, ngoba izidingo zabo zamanzi ziphansi. Ngaphezu kwalokho, imelana namakhaza nesithwathwa kuye ku -7ºC.

Amaqabunga awo ayashintshana, aluhlaza okotshani, futhi aphinyiwe, futhi akhiqiza izithelo zeglobose ezingaba ngamamilimitha ayisithupha ububanzi.
Ngenxa yokuzivumelanisa nezimo nokuqina kwayo (iphikisana no -7 )C), ikwazile ukuba yindlala kwezinye izingxenye zomhlaba, njengeNingizimu Afrika, iFlorida neHawaii, lapho kukhombise ukuthi kuyingozi kakhulu ezitshalweni zomdabu zase lawo mazwe. ESpain iyalinywa kabanzi, ikakhulukazi esifundeni saseMedithera, kepha iyinhlobo okumele iqashelwe ngenxa yemvelo yayo ehlaselayo.
Yisiphi kulezi zihlahla ze-savanna osithande kakhulu?
