However, scientific studies on the landscape dynamics of forest ecosystems in Haiti’s parks have received little attention. The objective of this study is to map and quantify the loss of forest cover in the natural national parks of Forêt des Pins (PNN-FP2), La-visite (PNN-LV) and Macaya (PNN-M) from 1985 to 2018. A diachronic analysis, thanks to the supervised classification of Landsat images based on landscape ecology analysis tools, was carried out. The results show a landscape dynamic materialized by forest cover losses of 56%, 36% and 46% respectively within the PNN-FP2, PNN-LV and PNN-M between 1985 and 2018, through the dissection and fragmentation of stains as opposed to the progressive dynamics of agricultural areas and bare soil underpinned by the creation and aggregation of stains. The annual rates of deforestation, significant between 1998 / 1999-2017 / 2018, varied between -0.09% and -2.72% depending on the park. Given that the landscapes of these three national parks studied are very dynamic, it is urgent to adopt a policy of their conservation supported by local socio-economic development measures.
