The Aliero local government area is located at approximately latitudes 11°03'S, 12°47'N and longitudes 3°6'W and 4°27'E. In kebbi state, north western part of Nigeria, It also has a total area of 412 square kilometer and is bordered in the east by Tambuwal Local government area of Sokoto state in the North West by Birnin Kebbi local government area in the South West by Jega local government area. The study was carried out in Aliero local government area, Kebbi state Nigeria. Leaf exchange is crucial in the lifecycle patterns of a tree species, these also includes leaf fall, leaf emergence, leaf flush, death or senescence (leaf onset and leaf offset). The study of leaf dynamics is termed leaf Phenology. Phonological phases are reoccurring biological events that signal changes in climate, environmental conditions and genetic factors during the developmental growth of plants. Cassia Sieberiana L trees maintained significant foliage was recorded in March in individuals which did not become leafless.
