Soil based heavy metals originating from anthropogenic activities on floristic composition of some selected sites in Northern Guinea savanna of Nigeria were investigated. 50m x 50m plots were laid in each of the three (3) selected sites with 30m espacement between each plot. This is replicated three (3) times to make a total of nine (9) plots in all. Soil samples were collected at a depth of 25m with a soil auger and heavy metal analysis was carried out with the use of atomic absorption spectrophotometer. The floristic compositions were evaluated using line transect method. Flora were enumerated in all the sites irrespective of the growth form, (i.e. trees, shrubs and herbs). The data collected were subjected to descriptive statistic, Anova using SPSS while the diversity index was calculated using Shannon Weiner method. The study revealed the presence of six (6) soil based metals in the selected sites, Cd; Cu; Mn; Ni; V and Zn. Significance differences (P |
