He ngahere tawhito, he mea ātaahua te āhua o ngā ngahere o Udzungwa: he piringa matomato o ngā mania kua whitia e te rā, e karapotia ana e ngā rākau teitei 30-mita (100 putu), ko ō rātou pou he mea whakarārangi ki te harore, ki te lichen, ki te mosses me te rarauhe..
Ko Udzungwa te whenua nui rawa atu, te whenua kanorau rawa atu hoki o te mekameka o ngā maunga nui tekau mā rua kua kapi i te ngahere e tū whakahīhī ana i te takutai moana papatahi o te rawhiti o Tanzania. E mōhiotia whānuitia ana ko ngā Maunga Eastern Arc, ko tēnei moutere o ngā papa whenua motuhake kua tapaina hoki ko ngā Galapagos o Awherika mō āna taonga o ngā tipu me ngā kararehe taketake, ko te mea tino mōhiotia ko te waioleta ataahua o Awherika. Ko Udzungwa anake i roto i ngā pae maunga tawhito o te Eastern Arc kua whakawhiwhia ki te mana o te pāka ā-motu. He ahurei hoki i roto i a Tanzania nā te mea ko tōna ngahere kati-MASL e horapa ana i te teitei o te 250 mita (820 putu) ki runga ake i te 2,000 mita (6,560 putu) me te kore e mutu.
Ehara a Udzungwa i te wāhi mātakitaki kararehe tuku iho, he mea kukume ia mō ngā kaihaerere. He whatunga pai o ngā ara ngahere ko te hikoi rongonui mō te haurua-rā ki te Wairere o Sanje, e ruku ana i te 170 mita (550 putu) i roto i te rehu kohu ki roto i te awaawa ngahere i raro. Ko te Ara Mwanihana e rua ngā pō e wero ana, e arahi ana ki te papa teitei, me ōna tirohanga whānui ki runga i ngā māra huka e karapoti ana, i mua i te piki ki te tihi o Mwanihana, te tuarua o ngā wāhi teitei rawa atu o te pae maunga.
E aro nui ana ngā tohunga manu ki Udzungwa mō te nui o ngā manu e kapi ana i te neke atu i te 400 ngā momo, mai i te oriole mahunga-kakariki ataahua, e kitea wawetia ana, ki te neke atu i te tekau mā rua ngā manu huna o te Eastern Arc. E whā ngā momo manu motuhake ki Udzungwa, tae atu ki te pārera ngahere i kitea tuatahitia i te tau 1991, ā, he whanaunga tata atu ki tētahi momo Āhia i tētahi atu manu o Āwherika. O ngā momo pirimia e ono kua tuhia, ko te Iringa red colobus me te Sanje Crested Mangabey kāore e kitea i hea atu i te ao – ko te mea whakamutunga, he mea whakamiharo, kāore i kitea e ngā tohunga koiora i mua i te tau 1979. Kāore e kore, kāore anō kia whakakitea e tēnei ngahere nui ōna taonga katoa: ko te tūhuratanga pūtaiao tonu ka tino tāpiri atu ki tana rarangi momo manu motuhake.
