Due to high pressures on coastal resources conflicting exploitation techniques and increasing population leading to loss of biodiversity in the ecosystem the value of coastlines has been diminished. The destruction of mangrove ecosystems has been on the increase since exploitation of oil and gas started in the Niger Delta resulting in replacement of mangrove vegetation by new vegetation species like nympa palms. The Kwale game reserve in the 1950s was rich in biodiversity but due to oil exploration gas production and poaching elephants and many flora and fauna have disapproved in the Reserve several animal species of conservation interest including Scalter s Guenon Delta Red Columbus the Crested Genet the Pygmy Hippo Chimpanzee and African Leopard have almost disappeared in the Niger Delta many plants of medicinal economic and cultural values such as Thaumatiococcus daniel sweetener Fegara sp. for sickle cell anemia and Rauvolfia vomitoria for treatment of high blood pressure and now rare in the Niger Delta .
