Mesquite ( Prosopis ) had been imported from its original home in North and South America, which
is ranked as a desert plants, that bear all environmental conditions, it had been planted in the Tokar Delta,
which is located in the Red Sea State in Sudan, as a belt against desert encroachment from which the city is
suffering annually, but after few years These trees deployed in the Delta and became a new risk to the
agricultural lands and the banks of Khor Baraka producing another problem. Now mesquite covers more than
half of the delta's area causing negative impact on all of the agricultural lands, surface, ground water and
irrigation channels. This paper is intended to assess the impact of the mesquite on the Tokar Delta and the
impact of efforts to control the spread of mesquite trees over 30 years. Also to provide guidelines for the
management and control of mesquite trees, using the capabilities of remote sensing and geographic
information systems in producing layers of maps and attributes, showing the spatial extent of these trees in the
Delta over the study periods of time, and conduct analysis to support decision makers to solve this serious
problem
