Abstract As a consequence of anthropogenic activities and climate change, accelerated terrestrial sediment runoff is causing the gradual mudification soft estuarine habitats worldwide. Increased mud content (< 63 µm) has been recognised to alter seagrass morphology cause declines in primary production unvegetated habitats. However, effect increased on meadows remains largely unknown. To address this, intertidal (Zostera muelleri) adjacent was measured in situ using benthic incubation chambers across an existing sedimentary gradient (nine sites spanning 5–33% content). An additional two mudflat (39–49% content) were also sampled expand gradient. Seagrass net (NPP) gross (GPP) greater than habitat did not vary with content, even after standardising GPP by photosynthesising biomass (i.e., photosynthetic efficiency). In contrast, habitat, efficiency declined increasing content. Inclusion negatively impacted NPP, habitat. Thus, while may have some resilience future increases (up 33%), further degradation loss will result expansion ultimately lead losses; seen most acutely areas high (≥ 39%).

Increased mud content (< 63 µm) has been recognised to alter seagrass morphology cause declines in primary production unvegetated habitats. However, effect increased on meadows remains largely unknown. To address this, intertidal ( Zostera muelleri ) adjacent was measured situ using benthic incubation chambers across an existing sedimentary gradient (nine sites spanning 5–33% content). An additional two mudflat (39–49% content) were also sampled expand gradient. Seagrass net (NPP) gross (GPP) greater than habitat did not vary with content, even after standardising GPP by photosynthesising biomass (i.e. photosynthetic efficiency). In contrast, habitat, efficiency declined increasing content. Inclusion negatively impacted NPP, GPP, habitat. Thus, while may have some resilience future increases (up ~33%), further degradation loss could result expansion ultimately lead losses, likely be most acute areas high (≥ 39%).
