Excessive deforestation of the Gishwati mountainous forest, with subsequent changes in biodiversity, are a result of growth in population density; creating a land cover map is important for evaluating and monitoring the trend of forest and biodiversity losses. Medium resolution imagery detects and monitors visual information, showing land use change of forested areas, and correlates it with other data gradients of biodiversity loss and changes occurring in the area.
