Wildlife of Benin - Riparian Forests

Riparian Forests

Riparian forests in Benin are important conservation sites that need more care than is currently available. These forests, which are flood-dependent and the flora that is dependent on this source of water, are seen in many parts of Benin. However, forest and savanna species are also part of this ecosystem as they have a combination of plants from various forest and savanna types. Hence, the riparian forests have been found to be more diverse than those of the single one-ecosystem-based vegetation. They also provide the needed categories of food for many animal and other forest species to survive.

The riparian forests ecosystem is in a limited area and spread in a linear shape. The forests account for at least one-third of the estimated 3,000 species of flora of Benin, with several valuable, rare or even endemic species. These forests are woodlands of semi-deciduous, dry, and open forest, and woodland savanna that occur along riverbanks or along streams. The physiognomy of this type of forest is highly variable with trees of average height of 14–18 metres (46–59 ft) and some places as high 20–25 metres (66–82 ft) with dense understorey. Adjacent more open ecosystems also affect the vegetation in these forests.

However, this ecosystem of hygrophile and edaphic freshwater forests is of general structural complexity and extent. It was in a state of extinction due to "shifting cultivation, grazing, selective cutting of valuable or rare tree species, road and dam construction, and over-exploitation of non-timber forest products" to meet the basic needs of rural community. This misuse also resulted in degradation of the ecosystem of rare plants and animals. It reached a chronic stage when indigenous multilayered plant communities became extinct in several areas with resultant creation of open fields, shrubs or grass savanna of least value. Thus, degradation of the ecologically rich system necessitated intervention at the Government level through enabling legislation to stop further damage to the ecosystem. The government of the Republic of Benin enacted a new forest law (no. 93-009) in July 1993, under which the uniqueness of riparian forests as refuge ecosystem for plant and wildlife of many kinds, was duly recognized. The rules enacted clearly defined that "clearance of wood and shrubs is not allowed within 25 metres (82 ft) at both sides of any waterway (article 28). Moreover, in the management plans of most forest reserves in Benin, gallery forests are to be left uncut, and rare species (e.g. Khaya spp. (Meliaceae), Milicia exelsa (Moraceae)) outside the gallery forests will not be cut either." In spite of such a legislation the enforcement is not effective as it is reported that uncontrolled and unplanned, mostly illegal utilisation of the forests resources continues, particularly in non-protected areas.
