Summary: The aim of our work was to undertake a scientific approach to the development of the Znadia and Gaoua forest into an ecological park. This work consisted first of all in gathering as much information as possible on the site, and then in carrying out an analytical study using Landsat 5&7 and Spot-5 satellite images, and thus evaluating the environment of these woodlands. The results obtained show a significant urban sprawl in the vicinity of the Gaoua forest as well as a progressive decrease in vegetation cover in the Znadia forest. In this context, a development plan has been drawn up to enhance these two sites in order to attract city dwellers to a place of relaxation and leisure and to hope for their participation in the protection of the heritage.
