This research implemented in Umdorman locality, Sudan. The objectives of this research are to (a) assess the urban trees status such as species, density, distribution and regulation; (b) draw a map of geographical distribution of the trees in the locality; (c) assess the role of urban trees that cover Umdorman and their role in improvement of the microenvironment; (d) determine the empty area capacity to establish a new urban forests. This research used the Google earth program to identify trees points, Excel file to save the coordinates as decimal degrees DD units (X=longitude and Y= latitude), the research found 22364 trees. The ArcMap software v 10.2 was used to analyze points and extract into maps. Eventually, the results showed the dominant trees species are Conocarpus erectus, Azadirachta indica and Albizia lebbeck, respectively (5580, 3426 and 2510 tree), as well as to other twelve trees species. The proportion area that is full of trees less than the proportion area that was empty. Thus, the research suggested planting other trees to cover the empty areas.
