Me ka moena a me ke au kahiko, ua like nā ululāʻau o Udzungwa me he mea hoʻohiwahiwa maikaʻi ʻia: he puʻuhonua ʻōmaʻomaʻo o nā glades i hoʻomālamalama ʻia e ka lā i hoʻopuni ʻia e nā lāʻau kiʻekiʻe he 30 mika (100 kapuaʻi), ua uhi ʻia ko lākou mau kumu me nā fungi, lichens, mosses a me nā ferns..
ʻO Udzungwa ka mea nui loa a me ka biodiverse o kahi kaulahao o nā mauna nui he ʻumikūmālua i uhi ʻia i ka nahele e kū hanohano ana mai ke kahakai pālahalaha o ka hikina o Tanzania. ʻIke ʻia ʻo ia hoʻi ʻo Eastern Arc Mountains, ua kapa ʻia kēia pae ʻāina o nā massifs kaʻawale ʻo ʻApelika Galapagos no kāna waiwai o nā mea kanu a me nā holoholona endemic, ʻo ka mea maʻamau ka violet ʻApelika palupalu. ʻO Udzungwa wale nō i waena o nā pae kahiko o ka Eastern Arc i hāʻawi ʻia i ke kūlana paka aupuni. He mea kū hoʻokahi nō hoʻi ia i loko o Tanzania no ka mea ʻo kona ululāʻau pani-MASL e uhi ana i nā kiʻekiʻe o 250 mika (820 kapuaʻi) a ʻoi aku ma mua o 2,000 mika (6,560 kapuaʻi) me ka ʻole o ke keakea.
ʻAʻole ʻo Udzungwa kahi wahi e nānā ai i nā holoholona hihiu maʻamau, he mea hoʻowalewale ia no nā poʻe hele wāwae. ʻO kahi pūnaewele maikaʻi loa o nā alahele ululāʻau e komo pū ana me ka huakaʻi hele wāwae hapalua lā kaulana i ka Sanje Waterfall, kahi e luʻu ai i 170 mika (550 kapuaʻi) ma waena o kahi ʻūhū noe i loko o ke awāwa ululāʻau ma lalo. ʻO ke Alahele ʻelua pō ʻoi aku ka paʻakikī ʻo Mwanihana e alakaʻi ana i ka pae kiʻekiʻe, me kona mau hiʻohiʻona panoramic ma luna o nā māla kō a puni, ma mua o ka piʻi ʻana i ka piko o Mwanihana, ʻo ia ka lua o ke kiʻekiʻe loa ma ka pae.
Ua makemake nā manu ʻōniʻoniʻo iā Udzungwa no ka waiwai o nā manu e pili ana i nā ʻano manu he 400 a ʻoi aku, mai ka oriole poʻo ʻōmaʻomaʻo nani a maʻalahi hoʻi e loaʻa a hiki i ka ʻoi aku ma mua o hoʻokahi kakini mau manu huna ma ka Hikina Arc. ʻEhā mau ʻano manu he mea kūikawā iā Udzungwa, me kahi manu ʻōniʻoniʻo i ʻike mua ʻia i ka makahiki 1991 a ʻoi aku ka pili loa i kahi ʻano ʻĀsia ma mua o nā manu ʻApelika ʻē aʻe. Ma waena o nā ʻano primate ʻeono i hoʻopaʻa ʻia, ʻo ka Iringa red colobus lāua ʻo Sanje Crested Mangabey ʻaʻole i ʻike ʻia ma kahi ʻē aʻe o ka honua - ʻo ka mea hope, he mea kupanaha, ʻaʻole i ʻike ʻia e nā biologist ma mua o 1979. ʻOiaʻiʻo, ʻaʻole i hōʻike kēia ululāʻau nui i kāna mau waiwai āpau: e hoʻohui maoli ka ʻimi ʻepekema e hoʻomau nei i kāna papa inoa like ʻole o nā manu ʻōniʻoniʻo.
