Abstract Globally, forest reserves are threatened by human induced deforestation and forest degradation. Within the Congo Basin, substantial deforestation has been quantified over the past years following the recent advancement in remote sensing and GIS applications in forestry research. Satellite images and ground based data are used to map deforestation, forest degradation and disturbances and their corresponding drivers. In Cameroon, recent studies show a general increase in deforestation over the past years. In most forest reserves of the Western Highlands, forest cover loss is basically as a result of rising population of in-situ and nearby settled communities. The Metchie-Ngoum Protection Forest Reserve (PFR) is but one. The study evaluates forest cover changes in the Metchie-Ngoum PFR using remote sensing and ground observations. It was revealed that forest cover though remained relatively stable over the study period (1984–2015), witnessed much degradation resulting to 36.11% estimated secondary forest cover by 1984. Secondary forest also experienced a cumulative loss to clearings/farms and built-up area from 1984 to 2000. The year 2000 was the most alarming. Forest loss is linked to oil palm expansion, increase population and built-up area and settlement related activities like logging. Faced with such rising threat on forest reserves, only a concerted action can guide sustainable forest management and conservation. The study thus recommends the design and implementation of a guided forest conservation policy which gradually applies proper sensitization, frequent visits by eco-guards, less intimidation, participatory forest mapping and the incorporation of forest communities in the sustainable management of forest reserves.
