The Sango Bay forests are a forest-wetland ecosystem with swamp forests, Acacia woodlands, grasslands, and papyrus swamps. The swamp forests, which extend into the adjacent
Minziro Forest of Tanzania, are a distinctive plant community, blending characteristic species from the lowland
Guineo-Congolian forests found further west in the
Congo Basin with
Afromontane species characteristic of Africa's mountains. Historically
Baikieaea insignis subsp. minor and
Afrocarpus dawei were the predominant canopy trees, although widespread logging has altered the species composition of the forest. The forests are home to populations of the monkeys
Ruwenzori colobus (Colobus angolensis ruwenzori) and
Uganda mangabey (Lophocebus ugandae). Savannas of
Vachellia kirkii are found along seasonally-flooded riverbanks. Papyrus swamps grow in permanently-flooded areas along rivers. The grasslands are predominantly the
tussock grasses
Miscanthidium violaceum,
Loudetia kagerensis, and
Themeda triandra. ==Sango Bay Forest Reserve==
