The Paul do Boquilobo is an importa

The Paul do Boquilobo is an important wetland ecosystem classified by Unesco as a MAB Biosphere reserve also awarded Ramsar site status, representing one of the most important habitats for the resident nesting colony of Cattle Egret (Bulbucus ibis). Yet owing to its location, it suffers from human induced impacts which include industrial and domestic effluent discharges as well as agricultural land use which have negatively impacted water quality. The current study reports the results obtained from the introductory monitoring programme of surface water quality in the Nature Reserve to emphasize the detrimental impact of the anthropogenic activities in the water quality of such an important ecosystem. The study involved physicochemical and biotic variables, microbial parameters and biological indicators. Results after 3 years of monitoring bring to evidence a poor water quality further impaired by seasonal patterns. Statistical analysis of data attributed water quality variation to 3 main parameters – pH, dissolved oxygen and nitrates, indicating heavy contamination loads from both organic and agricultural sources. Seasonality plays a role in water flow and climatic conditions, where sampling sites presented variable water quality data, suggesting a depurative function of the wetland.

Die Paul doen Boquilobo is 'n belangrike vleiland ekostelsel deur Unesco geklassifiseer as 'n MAB biosfeerreservaat ook Ramsar terrein status toegeken, wat een van die belangrikste habitat vir die inwoner nes kolonie Veereier (Bulbucus ibis). Tog weens sy ligging, dit ly aan die mens veroorsaak impak wat industriële en huishoudelike uitvloeisel ontlaai asook gebruik landbougrond wat 'n negatiewe watergehalte beïnvloed sluit. Die huidige studie is die resultate wat verkry is uit die inleidende moniteringsprogram van oppervlak watergehalte in die natuurreservaat die nadelige uitwerking van die menslike aktiwiteite in die kwaliteit van die water van so 'n belangrike ekosisteem beklemtoon. Die studie het fisies en biotiese veranderlikes, mikrobiese parameters en biologiese aanwysers. Resultate na 3 jaar van monitering bring om 'n swak gehalte water verder benadeel deur seisoenale patrone bewyse. Statistiese analise van data toegeskryf water kwaliteit variasie tot 3 belangrikste parameters - pH, opgeloste suurstof en nitrate, wat aandui swaar besmetting baie van beide organiese en landbou bronne. Seisoenaliteit 'n rol speel in die water vloei en klimaatstoestande, waar monsterneming webwerwe aangebied veranderlike watergehalte data, dui op 'n depurative funksie van die vleiland.
