摘要：A survey experiment was conducted during the rainy season (June to August) of 2013 in the floodplains of River Benue in streams, ponds, main drainage channels and marshy areas within Makurdi metropolis to determine the prominent aquatic macrophytes infesting these areas and their distribution during the rainy season. Macrophyte survey was carried out based on a combination of transects (WISER, 2011. A total of 10 aquatic macrophytes were identified, representing 8 families. Submerged macrophytes were observed to be absent in all the sample locations. Significant differences (p<0.05) were observed on percentage weed occurrence in all the sample locations surveyed. At Adubu, and Abattoir macrophyte abundance (MA), relative frequency (RF) and dominance index ( DI) were observed to be 100% each compared to the other locations while MA and DI were observed to be 100% and RF of 57.1% respectively at Industrial layout. This was followed by River Benue (MA=97.9%, RF=67.2%, DI=97.9%), University of Agriculture Annex, Katsina-ala street (MA=91.7%, RF29.7%, DI=183%), Berbesa (MA=72.7%, RF=34.8%, DI=43.6%). No macrophyte diversities were observed at Abattoir and Adubu had the least (0.0). To mitigate both the infestations of macrophytes therefore requires appropriate identification and possibly, enduring control approach(es) that may as well enhance greater water use.
