Seeing the Pond for the Reeds: Biodiversity of Rural Ponds

Abstract

Ponds in rural ecosystems may provide valuable habitat for a variety of cosmopolitan species, including those that are either fully aquatic or pond associated species in riparian habitats of mixed agricultural/wooded areas. We assessed the diversity of three rural ponds on private property (Southern 8’s Farm; Chesterfield, South Carolina), with different management histories using rapid species assessments. Surveys included aquatic dip-netting, sweep netting, acoustic surveys, camera trapping, and visual encounters. Identifications of organisms were performed using iNaturalist. In total, we compiled 240 unique taxonomic observations of different taxa across all ponds, representing 165 fully identified species (68.8% of observations). This consisted of 166 animal observations (largely arthropods, with some chordates), and 70 plant observations (mostly dicot flowering plants) and only 4 fungi observations. We found that iNaturalist provided a reliable method for identification of flora and fauna pond-associated species and should be considered for bioblitz surveys and rapid biological inventories to document species presence in riparian zones of agricultural ecosystems.
