Popis: Ecosystems and their services are essential to human well-being, but mining activities often cause adverse impacts on these services. Although impact of mining activities is experienced throughout the life of a mine, pre-mining phase was considered in this research because it determines the relationship of the mining industries with the community. In addition, mining companies must be conscious of how to mitigate its impacts on the environment in every stage as much as possible. Past researchers either have stated the impacts of pre-mining on the environment not explicitly considering the ecosystem services, or they have assessed the effects of mining on the ecosystem not taking into account the pre-mining activities or the ecosystem services. In this research, an existing methodology of ecosystem services was applied to the oil sands deposits located in Ondo state, Nigeria. The results include an appraisal of the demographic information, land use maps, types of ecosystems, ecosystem services, and the use of these services to the communities. The results of the prioritized ecosystem service, proposed mitigation measures that can be taken, and an assessment on the outcome of the proposed mitigation measures on the ecosystem services were also obtained. The conclusions are that the ecosystem service review can be an appropriate approach for mitigating impacts of pre-mining activities on ecosystem services. However, the ecosystem services methodology that was applied can be improved by assessing the outcome of the mitigation measures to know if there will be any significant reduction in impact occurrences and by giving the feedback of the mitigation measures to the community.
