Niger Delta mangroves are the largest in Africa, but uncontrolled anthropogenic activities had reduced their population size. The reduction from large to small mangrove stand has some ecological implications on species populations. For instance, stochastic events such as flooding, landslides, sea level rise, high temperature, and humidity affect small populations. Human-mediated actions of random deforestation for firewood production, canalization, and de-silting of waterways, lead to the complete elimination of mangrove stands in specific locations. The cumulative effect of these actions can result in local extinction and loss of genetic variation of mangroves. Destruction of mangroves over the years is detrimental to other species that inhabit the mangroves in the Niger Delta (e.g., fishes, crabs, etc.). This situation can be reversed or stopped if effective protective measures are adopted. Strict protective measures can be done in areas that are highly impacted i.e., regions where oil and gas exploration or massive deforestation activities had occurred. Limited protection can be done in areas with low impact, and is known as a win-win conservation where the peoples welfare is considered. Here, indigenous people are employed to help in the protection of the forest and in return are allowed to exploit its resources.
