R
eclamation of coastal wetlands has a major impact on biodiversity globally. We investigated the feasibility of using biodiversity
offsets to mitigate the impacts of coastal reclamation on biodiversity using impacts of reclamation on macrobenthic diversity
in the Yellow River Delta region in China as a case study. We estimated 472 km2 of coastal wetlands have been reclaimed in the
Yellow River Delta between 1980 and 2015, which is an average of 13.5 km2 of coastal wetland reclaimed per year. We developed a
methodology to calculate biodiversity offset ratios for coastal wetlands using inputs including: biodiversity lost due to development
and gained due to restoration offsets, the delay between reclamation and restoration, the amount of biodiversity lost due to leakage
and an annual discount rate. Offset ratios were particularly sensitive to the baseline used for the counterfactual. However, the relatively
short time it takes for macrobenthos to be restored in coastal wetlands suggests that biodiversity offsets are theoretically feasible for
mitigating the impacts of reclamation on this assemblage. However, we estimated that the area of suitable land available within the
Yellow River Delta was sufficient to offset 1980-2015 years of reclamation, which suggests that other strategies such as avoiding
future reclamation and reducing the impacts of future reclamation on macrobenthos are also necessary if no net loss of microbenthic
biodiversity is to be achieved in the Yellow River Delta Region of China. Our results have important implications for conservation in
the face of ongoing coastal reclamation.

Shuling Yu has her expertise in biodiversity offsetting, wetland ecology, wetland restoration, and wetland management. Wetlands are economically and ecologically
important ecosystems, but have been increasingly degraded by anthropogenic impacts. Her current project focuses on optimizing biodiversity offset strategies for
degraded habitat from coastal reclamation.
