Native oyster reefs once dominated many estuaries, ecologically and economically. Centuries of resource extraction exacerbated by coastal degradation have pushed oyster reefs to the brink of functional extinction worldwide. We examined the condition of oyster reefs across 144 bays and 44 ecoregions; our comparisons of past with present abundances indicate that more than 90% of them have been lost in bays (70%) and ecoregions (63%). In many bays, more than 99% of oyster reefs have been lost and… 
Loss of an ecological baseline through the eradication of oyster reefs from coastal ecosystems and human memory
The collapse and extirpation of native oyster reefs (Ostrea angasi) over the course of a commercial fishery in Australia is evaluated and a model of generational amnesia is considered to reflect a collective, intergenerational amnesia.
Restoration potential of Asian oysters on heavily developed coastlines
Reef‐building oysters historically provided the main structural and ecological component of temperate and subtropical coastal waters globally. While the loss of oyster reefs is documented in most
Maximizing the benefits of oyster reef restoration for finfish and their fisheries
Global declines in oyster reefs have resulted in reduced habitat heterogeneity, extent and quality for some coastal finfish, potentially reducing fish populations and catches. It is well established
Do restored oyster reefs benefit seagrasses? An experimental study in the Northern Gulf of Mexico
Oyster reefs and seagrass beds are being lost worldwide at alarming rates. These habitats provide many services to humankind and, thus, much effort has been dedicated to their restoration. Here, we
Contemporary Oyster Reef Restoration: Responding to a Changing World
Globally, there is growing interest in restoring previously widespread oyster reefs to reinstate key ecosystem services such as shoreline protection, fisheries productivity and water filtration. Yet,
Feasibility of shellfish reef restoration in a south-western Australian estuary
With 85% of oyster reefs lost around the world within the last 130 years, these reefs are now one of the most threatened marine habitats in the world and in Australia less than 10% of naturally
Decadal changes in oyster reefs in the Big Bend of Florida's Gulf Coast
Oyster reefs are among the world's most endangered marine habitats with an estimated 85% loss from historical levels worldwide. Oyster reefs offer diverse ecological and social services for people
The value and opportunity of restoring Australia's lost rock oyster reefs
Recognizing the historical loss of habitats and the value and opportunities for their recovery is essential for mobilizing habitat restoration as a solution for managing ecosystem function. Just 200


Unprecedented Restoration of a Native Oyster Metapopulation
Field evidence is presented of a successful restoration of a large metapopulation of native oysters in the Great Wicomico River, a tributary on the western shore of the Chesapeake Bay, that is the largest of any native oyster worldwide and validates ecological restoration ofnative oyster species.
Success of constructed oyster reefs in no-harvest sanctuaries: implications for restoration
Dramatic declines in populations of the eastern oyster Crassostrea virginica are a symp- tom of degradation in many US Atlantic and Gulf of Mexico estuaries. We sampled 94 oyster reefs (88
Oysters are ecosystem engineers that create biogenic reef habitat important to estuarine biodiversity, benthic-pelagic coupling, and fishery production. Prevailing ex- planations for the dramatic
Loss, status and trends for coastal marine habitats of Europe
Over the centuries, land reclamation, coastal development, overfishing and pollution have nearly eliminated European wetlands, seagrass meadows, shellfish beds, biogenic reefs and other productive
Fishing down the coast: historical expansion and collapse of oyster fisheries along continental margins.

This work evaluates the expansion and collapse of oyster fisheries in 28 estuaries along three continental margins through the analysis of historical proxies derived from fishery records to infer when oyster reefs were degraded.
Conserving oyster reef habitat by switching from dredging and tonging to diver-harvesting
A major cause of the steep declines of American oyster (Crassos- trea virginica) fisheries is the loss of oyster habitat through the use of dredges that have mined the reef substrata during a century
Estimated enhancement of fish production resulting from restoring oyster reef habitat: quantitative valuation
We reviewed studies providing quantitative measurements of abundance of fishes and large mobile crustaceans on oyster reefs and on nearby sedimentary habitat in the southeast United States. For each
Accelerating loss of seagrasses across the globe threatens coastal ecosystems
This comprehensive global assessment of 215 studies found that seagrasses have been disappearing at a rate of 110 km2 yr−1 since 1980 and that 29% of the known areal extent has disappeared since seagRass areas were initially recorded in 1879.
