As an ecosystem engineer oysters provide "supporting" ecosystem services, along with "provisioning", "regulating" and "cultural" services. Oysters influence nutrient cycling, water filtration, habitat structure, biodiversity, and food web dynamics.[23] Oyster feeding and nutrient cycling activities could "rebalance" shallow, coastal ecosystems if restoration of historic populations could be achieved.[24] Furthermore, assimilation of nitrogen and phosphorus into shellfish tissues provides an opportunity to remove these nutrients from the environment, but this benefit has only recently been recognized.[24][25][26] In California's Tomales Bay, native oyster presence is associated with higher species diversity of benthic invertebrates[27] but other ecosystem services have not been studied.[28] As the ecological and economic importance of oyster reefs has become more widely acknowledged, creation of oyster reef habitat through restoration efforts has become more important- often with the goal of restoring multiple ecosystem services associated with natural oyster reefs.[29]
