Mysterious Treasure

The wet forests of the Eastern Congolian Swamp Forest ecoregion are a hidden treasure. These forests are not as well studied as those in the surrounding ecoregions that are subject to less flooding, and there are many species here that are yet to be discovered by scientists. The ecoregion is frequently flooded by the Congo River, which makes the high forest canopy an ideal refuge for a great number of species, such as Muton's soft-furred mouse, Allenâs swamp monkey, the Congo sunbird, and the tiny wax frog.

Special Features Special Features

The swamp forests that make up this ecoregion lie on flat land along the eastern bank of the Congo River. This mighty river frequently pours over its banks, flooding the forests. During flooding, animals are forced to either take to the treetops or move to higher ground, so many animals tend to be arboreal, with obvious exceptions such as elephants.

Did You Know?
Allenâs swamp monkeys live in swamp and levee forests bordering the Congo River. When the floods come and inundate the forest floor, the monkeys spend most of their time in the trees. After the floods, they spend more time on the ground. Many thousands of years ago, when there was a huge lake where the Congo now flows, swamp monkeys most likely lived along the lakeâs edges.

Wild Side

In the treetops, monkeys called golden-bellied mangabeys eat fruit, nuts, insects, shoots, and leaves. In open areas, one may hear the thumping call of tiny wax frogs. Congo sunbirds feed on large red flowers of trees. Bonobos--a species of ape--roam the forest floor in search of fruits, shoots, leaves, seeds, flowers, bark, rodents, snakes, and insects. Elephants also live in these forests and feed on vegetation in numerous openings and clearings.

Cause for Concern

Although logging has been carried out in some areas of this ecoregion, the habitat is fairly intact and the forest appears to be regenerating well where it had previously been cut over. However, poaching is decimating forest elephant and bonobo populations. Little is known about biodiversity in this region, and we may be losing species that have yet to be discovered.
