Rapid population growth and coastal development are primary drivers of marine habitat degradation. [...] Key Result Our analysis indicates that 22 842 km of continental US shoreline – approximately 14% of the total US coastline – has been armored. We also consider how socioeconomic and physical factors relate to the pervasiveness of shoreline armoring and show that housing density, gross domestic product, storms, and wave height are positively correlated with hardening. Over 50% of South Atlantic and Gulf of…Expand

Hurricane damage along natural and hardened estuarine shorelines: Using homeowner experiences to promote nature-based coastal protection
Abstract Growing coastal populations, rising sea levels, and likely increases in the frequency of major storm events will intensify coastal vulnerability in coming decades. Decisions regarding howExpand
A Global Analysis of Anthropogenic Development of Marine Turtle Nesting Beaches
The Intergovernmental Panel on Climate Change predicts that sea levels will rise by up to 0.82 m in the next 100 years. In natural systems, coastlines would migrate landwards, but because most of theExpand
Quantifying the effectiveness of shoreline armoring removal on coastal biota of Puget Sound
TLDR
This analysis shows that removing shoreline armoring is effective for restoration projects aimed at improving the health and productivity of coastal ecosystems, and these results may be widely applicable. Expand
Risk of shoreline hardening and associated beach loss peaks before mid-century: Oʻahu, Hawaiʻi
TLDR
Results show an increase in shoreline vulnerability to hardening with SLR governed by backshore land use patterns, and maximum risk of shoreline hardening and beach loss is projected to occur from modern-day and near-term hardening because of the heavily developed aspect of some shoreline segments.

Restoration Effectiveness of Living Shorelines in the Salish Sea
Abstract In human-impacted coastal ecosystems, living shorelines are becoming a common restoration technique. However, we lack a comprehensive understanding of the ecological and physical benefits,Expand

Ecological Consequences of Shoreline Hardening: A Meta-Analysis
TLDR
A meta-analysis of studies comparing the ecosystem services of biodiversity and habitat provisioning along shorelines with versus without engineered-shore structures found that biodiversity and abundance supported by riprap or breakwater shorelines were not different from natural shorelines; however, effect sizes were highly heterogeneous across organism groups and studies.

Living shorelines can enhance the nursery role of threatened estuarine habitats.
TLDR
Living shorelines can enhance some ecosystem services provided by marshes, such as provision of nursery habitat, and were detected on shores with sills three or more years after construction, but not before. Expand
