Savannah Australia

Mākou e hoʻomau mākou theme like o ka hoʻoneʻe i Australia "He aha mea he savannah, a ma ka mea e". Eia, keia wahi ma kona ano maoliʻano nui ma ka akau o ka 20 degere hema ka latitu. A hiki i ka hikina kau typical savanna (a noho no hoi lakou i ka mokupuni hema o New Guinea). I loko o ka wai wa pono, ua uhiia ka aina me ka nani flowering mea kanu: ka orchid ohana, buttercup, lilia a me nā kiliala. Ano laau - he laau, eucalyptus, casuarinas. He laau a pau me ka manoanoa nui ilpko o, ma o ka hoʻonui lako o ka ona mau. Ka mea, i loko o 'ana, mea haawi wale i ka ai-kapaia omole laau. He ke alo o kēia kūlana mea kanuʻo savanna Australia i iki okoa mai ka savannah, i i ke aupuni 'ana ma nā' âinapuni.

Kēia ciia ua hui me sparse ululāʻau, a i na poe ma kekahi mau? Ueo o eucalyptus. Eucalyptus woodlands kūlana 'i ka nui loa o ka'ākau kapakai o ka aina a me ka nui o ka Cape York mokupuni.

Ke kūlana o ka savannah no ke kanaka

Ma hope o mākou i loaʻa mai ma ka au mamuli mea o ka savannah, a ma ka mea e, ka mea e e olelo ana ia mau mau mea maoli hula he kūlana nui no kānaka. Mau wahi i makua peanuts, mānoanoa, jute, pulupulu, ke ko. I ka maloo wahi aho hoʻomohala holoholona i ka'āina. Ua mea i ke kumukuai o 'ana i kumumanaʻo ana kekahi laha' o ka laau kupu ana ma ka aina i manaoia e e loa waiwai (e like me, teak).

I loko nō o ka mea kiekie oia ka mea nui, i ke kanaka, Eia naʻe, mau e systematically luku i ka savannah. No ka laʻana, maʻAmelika Hema i ka hopena o ke kuni nā mahinaʻai pepehi laau he nui. Nui mau mea o ka savannah mai ka manawa i ka manawa i mao mai o ka ululaau. More nei, ma Australia no ka holoholona i wahi e hanai makahiki a mao ae ma kahi o 4.800ʻahā like mika. km Ke ululaau. Ano, e kaulia ana i kēia mau hanana. Detrimental ia ma ka ke kaiaola o ka savannah i na mea he nui mea lahaʻole laau (Nile, he laau, landata svodchaya, na ohia, etc.).

Ka Huliau loli alakai i ka loli ma ka mana a me ka 'ole o ka savannah. E like me ka hopena o ka hoʻomehana honua hoomanawanui woody mea kanu. Au makemake e manaoio i ka poʻe nō hoomaka ma ke kokoke wā e hiki mai , e hoʻopale ano.
