Geography and Landscape
The important regional centre to the park is Arba Minch in the Main Ethiopian Rift. Approximately 15% of the park consists of lakes including Lake Abaya in the north and Lake Chamo in the south. Part of the habitat consists of the groundwater forest and shoreline of the lakes, but there are dry grassy plains, and most of the park is covered in thick bushland and the wooded valleys and foothills of the Amaro Mountains. The altitude ranges from 1,108 meters above sea level at the shore of Lake Chamo to 1,650 meters on Mount Tabala in the north-east, renowned for its hot springs.
The forest between the two lakes and by the Kulfo river is dominated by Ficus sycamorus which can grow up to 30m tall. Extensive areas to the west of Lake Abaya were cleared in the 1960s and 1970s to establish large-scale mechanized farms for cotton and other crops.
The freshwater swamps at the mouth of the Kulfo River and in Lake Chamo are dominated by Typha angustifolia, tall waterside grasses and the small leguminous trees, such as Aeschynomene elaphroxylon and Sesbania sesban. Taller trees found in the park include Dichrostachys cinerea, Acacia tortilis, Balanites aegyptiaca and less common Acacia nilotica. The southern part of the park is domainated by edaphic grassland and a calcareous black clay soil underneath with Dobera glabra, Acacia tortilis and the grass Chrysopogon aucheri forming much of the landscape.
Both Lake Abaya and Chamo have substantial fish populations, notably Nile perch, which forms the basis of the local fishing industry. Crocodiles inhabit both lakes and there is a crocodile farm near Lake Abaya. At Chamo crocodiles are exploited for their skins.

Famous quotes containing the words geography and, geography and/or landscape:
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
