“…The habitat association of dragonflies and damselflies in Africa has been described by many researchers (e.g., Vorster et al, 2020). Moreover, several studies have shown that species assemblages of odonates are influenced mainly by aquatic and terrestrial vegetation (Paice, Chambers, & Robson, 2017). Studies have shown that adult diversity and abundance is often positively correlated with local abundance of vegetation (Remsburg & Turner, 2009).…”

Odonata (dragonflies and damselflies) are efficacious for management and conservation efforts in freshwaters. In recent times, increased effort has gone into enhancing awareness, data and information on dragonflies among scientists and policymakers. Here, we examined the Odonata community of dams within the Matobo National Park, a world heritage site in southern Zimbabwe. Specifically, we determined diversity of larval and adult odonate in five dams over one year. Several physico-chemical parameters were measured, including pH, total dissolved salts (TDS), electrical conductivity (EC). Further, we assessed how habitat types (i.e., detritus, sand, gravel, plant type) affect Odonata communities. In addition, surveys were conducted to identify critical threats to Odonata in the Matobo National Park and surrounding areas. Broadly, results showed that Odonata nymphs and volant adults did not change predictably across all sampling occasions. Further, pH was positively correlated with Libellulidae and Platycnemididae, whereas TDS and EC were positively correlated with Libellulidae, Platycnemididae and Macromiidae. Contrariwise, Gomphidae were found to be negatively correlated to TDS, EC and pH. The threat analyses identified natural system modifications, agricultural expansion and intensification, as well as human intrusions and disturbance as the major threats to Odonata and freshwater resources in Matobo National Park. Taken together, these data provide baseline data that will be useful for future monitoring of threats and subsequently conservation strategies in the Matobo National Park and other protected areas in Southern Africa.

“…Aquatic submerged macrophytes support many important services in stream ecosystems. They provide food and habitat for invertebrates and fish [ [1] , [2] , [3] , [4] ], alter the physico-chemical environment [ 5 ] and affect nutrient cycling [ 6 ]. However, increased anthropogenic influences have impacted stream macrophyte communities and the services they support [ [7] , [8] , [9] ].…”
