Landscape metrics predict habitat redundancy of restored oyster reefs for recruitment enhancement of dominant estuarine fish

Structured biogenic habitats in estuarine and coastal landscapes (or seascapes) augment nekton species' production; yet, landscape setting may make restored habitats functionally redundant to co‐occurring habitats for some species. Few relationships between recruitment enhancement and continuous landscape metrics have been quantified, limiting our ability to incorporate functional redundancy into restoration practice. To address this gap, we quantified two landscape metrics, per cent structure of proximal habitat and near distance to co‐occurring structured habitats, for experimentally restored oyster reefs in an intertidal landscape in Middle Marsh, North Carolina, USA. We then examined relationships between each landscape metric and recruitment enhancement of juvenile pinfish (Lagodon rhomboides), a species that uses multiple biogenic habitats and has high site fidelity as juveniles. We estimated that reefs with
