On the north-west side the most abundant plant species are "Cenchrus echinatus", "Sida rhombifolia", and "Corchorus aestuans". These plants compose a shrub cover up to 30 cm in height and are intermixed with "Eclipta", "Phyllanthus", and "Solanum", as well as a taller plant, "Brassica juncea". A unique feature is that the vegetation is arranged in parallel rows of species, with dense rows of taller species alternating with lower, more open vegetation. This was assumed to be a result of the phosphate mining method of trench-digging.
