I- ishidi noma amathafa asezindaweni ezishisayo i-ecosystem ebonakala ngamathafa ayo anotshani anezihlahla ezimbalwa ezifushane ezihlakazekile. Inesimo sezulu esifudumele nezinkathi ezimbili zonyaka: enye imanzi enye yomile, okuchaza ukwehluka okuncane kohlaza lwayo. Umhlabathi wayo untula izakhi zomzimba eziningi futhi uqukethe utshani obukhulu obuluhlaza noma obuphuzi.

Kunezinhlobo ezahlukahlukene ze-savanna; kuzo isimo sezulu, uhlobo lomhlabathi, izilwane nezimbali kuyahlukahluka. Zonke zitholakala eningizimu yezwe, okwaziwa kakhulu ezwenikazi lase-Afrika, ngokwesibonelo: amaSavana aseSudan, indawo eyihlathi yaseKenya. Kunezindawo ezingama-savanna eNingizimu Melika, enyakatho ye-Australia naseNdiya.

Izinhlobo ze-savanna

Ama-Savannas ahlukaniswa ngokwesimo sezulu nohlobo lwawo lomhlabathi ku:

• I-Savanna yendawo esentabeni. Eyaziwa nangokuthi i-chaparral, i-grassland, i-plain noma i-pampas, inikeza inhlabathi ephansi evundile ethatha umbala obomvu (ocebile ngensimbi). Isimo sezulu sayo sifudumele. Izikhathi ezimbili zemvula (ezidala ukwakheka kwamaxhaphozi) zivame ukushintshana nesomiso (esingadala imililo yemvelo). Ngokwesibonelo: indawo eyiSerengeti savanna eTanzania.
• I-savanna epholile. Lwaziwa nangokuthi i-prairie, lolu hlobo lwe-savanna lunenhlabathi evundile, yize isimo sezulu sivame ukubanda futhi somile ebusika. Izinkathi ezimbili zonyaka ziyashintshana: enye ifudumele enye ishisa.
• I-savanna yaseMedithera. Lolu hlobo lwe-savanna lunenhlabathi eyomile futhi encane kakhulu evundile. Imvula iyindlala, edala indawo eyomile.
• Intaba eyi-savanna. Ukuba sezindaweni eziphakeme (izindawo eziphakeme kakhulu noma ezingaphansi kwezintaba) kulolu hlobo lwesihlabathi, isimo sezulu siyabanda futhi sihlushwa yimvula eningi.

Izimbali zeSavanna

Ngenxa yesimo sezulu sabo nenhlabathi yabo engavundile kakhulu, imifino ye-savanna ijwayele ukugcina amanzi ezimpandeni zayo ezijulile, inembewu emelana kakhulu nesomiso futhi ivumelane nezimo zezulu ezimbi kakhulu.

I-savannah ibonakala ngezinhlobo zayo ezihlukene zezihlahla nezitshalo eziphansi. Kugqama utshani nezihlahla. I-savannah inezinamba ezimbalwa zezihlahla (ezivame ukutholakala osebeni lwemifula).

Endabeni ye-savanna yase-Afrika, izihlahla ezivame kakhulu ama-acacias kanye nama-baobabes kanti utshani obuvame kakhulu utshani be-rhodesian, utshani lukalamula, i-star grass kanye ne-bermuda grass.

Izilwane zaseSavannah

Izilwane ziyahlukahluka ngohlobo lwe-savanna. I-savanna yase-Afrika, okuyiyona efundwa kakhulu futhi eyaziwayo, ibonakaliswa ngokuba khona kwezilwane ezincelisayo ezinemilenze emide futhi enamandla, phakathi kwazo kukhona izinyamazane, izindlulamithi, izindlovu, amabhubesi, amahlosi, izimvubu nezinye izilwane ezinwabuzelayo njengezingwenya, izibankwa nama-igwana. Eziningi zalezi zilwane zifuduka ngenkathi eyomile ziye kwezinye izifunda ezinhle.

Inani elikhulu lezilwane ezingama-savanna yimifino edla utshani futhi idla otshanini notshani; kukhona nenani elikhulu lezilwane ezidla lezi zilwane.

Izinyoni zeSavanna zibonakala ngokuba namaphiko amakhulu azivumela ukuba zihambe amabanga amade, ngoba eziningi zazo ziyafuduka. Kunenani elikhulu labakhwabanisi.
