Biodiversity Recovery

Habitat Degradation and Biodiversity Recovery

Owing to prolonged dry spells and climatic variation, high densities of elephants that impacted on the wood cover eroding some areas of the sanctuary of its dense vegetation and highly modifying the locality. In an effort to reverse the loss, an electric enclosure was set up in 2009 for the exclusion of the mega herbivores and to allow for plant recruitment within the exclusion plot.

The natural regeneration was supplemented through tree planting of the indigenous species by visitors and inclusivity of the local community in creating an awareness and sensitization on threats to the environment and wildlife survival.

Riparian forest ecosystems are important for their high productivity of biomass, significant biodiversity, and ecological services. The disruption of Bura river flow within the sanctuary attributed to prolonged siltation and subsequent loss of streams channeling water to this river, has led to severe loss of tree cover and undergrowth that characterizes the riparian habitat. This has had a major impact on downstream forest productivity and ecological services, suppression of tree growth and early tree mortality, thus negatively impacting on the habitat’s health and hydrology of the river.

Following the successful restoration of the habitat at the Bura enclosure (32.5 Acres) within the Sanctuary, two other separate electric enclosures: one along the riparian zone near Salt Lick Safari Lodge (37 Acres), and another near Bura dam (32.5 Acres), were commissioned in 2020 to recover riparian forest, whose canopy cover, undergrowth and contiguity had been greatly affected.

It is expected vegetation reclamation that will emsue will recover the contigous chatracter of the forest and restore the buffer zone plants that are vital for the mitigation and control of nonpoint source pollution, enhanced infiltration of surface runoffs and in the provision of habitat and food for riparian plant and animal species.
