ABSTRACT
The present study documents the frequency of occurrence of lawn plant species growing within some motor mechanic workshops in Benin City metropolis, using Quadrant method of sampling and identification of plants. The results shows that the Species compilation of plants found within the Auto Mechanic Workshops were; Axonopus compresus, Eleusine indica, Eragrotis tenella, Ageratum conyziodes, Cyperus esculentum, Commelina erecta, Cyperus rotundus and Matracarpus villosus, Eragrotis tenella, Cynodon dactylon, Perotis indica, Mariscus alternifolius, Oldenlandia corymbosa, Emilia coccinea and Phyllanthus amarus. In Bright Engineering Auto Mechanic Workshop, Poaceae family had the highest number of species (17) and 55 percentage (%) occurrence, while the Cyperaceae family had lowest number of species (4) with and 13 percentage (%) occurrence. The total number of species found in this Mechanic Workshop was 31 comprising 3 families. In Eric and Sony mechanic workshop, Cyperaceae family had the highest number of species (16) and percentage occurrence (64%), while the Commelinaceae family had lowest number of species (6) with and 20 percentage occurrence (%). The total number of species found in this Mechanic Workshop was 30 comprising 3 families. In Ekogiawe and Sons auto mechanic workshop, Poaceae family had the highest number of species (19) and 45 percentage occurrence (%), while the Phllanthaceae family had lowest number of species (2) with and 3 percentage occurrence (%). The total number of species found in this Mechanic Workshop was 65 comprising 5 families. In Agbons auto mechanic workshop, Poaceae family had the highest number of species (40) and 59 percentage occurrence (%), while the Rubiaceae family had lowest number of species (4) and 7 percentage occurrence (%). The total number of species found in this Mechanic Workshop was 68 comprising 4 families. This findings therefore presents a list of plants that are likely candidates for remediation strategies and management for spent engine oil contaminated soils.
