Njengoba zikhula futhi zikhula isikhathi eside, amahlathi ase-Udzungwa abonakala ekhanga kakhulu: indawo yokukhosela eluhlaza yama-glades anombala welanga azungezwe yizihlahla eziphakeme ngamamitha angu-30 (100 feet), izindonga zazo zigcwele isikhunta, ama-lichen, ama-mosses nama-fern..
I-Udzungwa iyisiqhingi esikhulu kunazo zonke futhi esinezinto eziphilayo eziningi kakhulu ochungechungeni lwezintaba ezinkulu eziyishumi nambili ezigcwele amahlathi eziphakama ngendlela emangalisayo zisuka ogwini oluyisicaba olusempumalanga yeTanzania. Eyaziwa ngokuthi i-Eastern Arc Mountains, lesi siqhingi sezintaba ezikude siphinde sabizwa ngokuthi i-African Galapagos ngenxa yengcebo yaso yezitshalo nezilwane ezitholakala endaweni ethile, okuvame kakhulu ukuthi i-African violet ethambile. I-Udzungwa yodwa phakathi kwezintaba zasendulo ze-Eastern Arc enikezwe isimo sepaki kazwelonke. Ihlukile futhi eTanzania ngoba ihlathi layo elivaliwe le-MASL lihlanganisa ukuphakama kwamamitha angu-250 (820 feet) kuya ngaphezu kwamamitha angu-2,000 (6,560 ft) ngaphandle kokuphazamiseka.
Akuyona indawo evamile yokubuka izilwane zasendle, i-Udzungwa iyindawo ekhangayo yabahamba ngezinyawo. Inethiwekhi enhle yezindlela zamahlathi ihlanganisa ukuhambahamba okuthandwayo kwesigamu sosuku ukuya eSanje Waterfall, ewela amamitha angu-170 (amamitha angu-550) ngokusebenzisa i-spray enenkungu esigodini esinamahlathi ngezansi. Indlela iMwanihana Trail eyinselele yezinsuku ezimbili iholela ethafeni eliphezulu, enemibono emihle kakhulu yezindawo zikashukela ezizungezile, ngaphambi kokukhuphukela esiqongweni saseMwanihana, indawo yesibili ephakeme kunazo zonke ohlangeni.
Izazi zezinyoni zikhangwa yi-Udzungwa ngenxa yengcebo yezinyoni ehlanganisa izinhlobo ezingaphezu kuka-400, kusukela ku-oriole enhle futhi etholakala kalula enekhanda eliluhlaza kuya ezilwaneni eziyimfihlo ezingaphezu kweshumi nambili zase-Eastern Arc. Izinhlobo ezine zezinyoni zihlukile e-Udzungwa, okuhlanganisa ne-partridge yehlathi eyatholwa okokuqala ngo-1991 futhi ehlobene kakhulu nohlobo lwase-Asia kunanoma iyiphi enye inkukhu yase-Afrika. Ezinhlobo eziyisithupha zezilwane ezitholakalayo, i-Iringa red colobus kanye ne-Sanje Crested Mangabey zombili azikho kwenye indawo emhlabeni - lokhu kwamuva, ngokumangalisayo, akubonanga ososayensi bezinto eziphilayo ngaphambi kuka-1979. Akungabazeki ukuthi leli hlathi elikhulu alikakayivezi yonke ingcebo yalo: ukuhlola okuqhubekayo kwesayensi ngokuqinisekile kuzokwengeza ohlwini lwayo oluhlukahlukene lwezinhlobo zezilwane ezitholakalayo.
