Functional streams are intimately connected to riparian areas through reciprocal flows of materials known as ecological subsidies. Aquatic-to-terrestrial subsidies, including emergent aquatic insects and materials deposited on the floodplain during high flows, play a critical role in riparian ecosystem function. Widespread stream degradation has weakened floodplain connectivity and reduced subsidy fluxes. Restoration often aims to improve floodplain connectivity. However, as treatments are widely implemented, it is unclear whether they effectively recover important linkages between aquatic and terrestrial environments. We used a before-after-control-impact study to investigate whether beaver dam analogs (BDAs) and plug-and-pond treatments reestablished aquatic-terrestrial subsidies. We found BDAs did not affect the total abundance of emergent aquatic insects, nor did these treatments affect the abundance of emergent Chironomidae, Ephemeroptera, or Trichoptera. The abundance of non-Chironomidae Diptera significantly increased following installation of BDAs. Plug-and-pond treatments significantly increased total emergent insect abundance, as well as the abundance of emergent Chironomidae and Ephemeroptera. The abundance of non-Chironomidae Diptera and Trichoptera were not significantly affected by plug-and-pond treatments. Preliminary stable isotope analysis of d13C, d15N, and d2H and mixing model results suggest that these emergent aquatic insects were ingested by riparian consumers. Following treatment installation, the proportion of diet that is aquatically derived increased for some riparian functional feeding groups (e.g. spiders, non-spider predators). These dietary shifts altered the biological width of the stream and overlap of isotopic niches for aquatic and riparian consumers. Although final isotopic data are forthcoming, our initial results indicate that BDAs and plug-and-ponds can reestablish energy flows and improve aquatic-terrestrial connectivity. This result is important for managers who identify improved connectivity and ecosystem resilience as restoration treatment goals. Furthermore, our study provides a framework to monitor whether restoration reestablishes critical ecosystem functions including subsidy flows.
