“…Overall, strategies and approaches to oyster reef restoration are diverse and often regionally unique. Examples include the usage of: metal-based materials, such as gabions [5][6][7] or crab traps [8], rock-based materials, such as ReefBall™, domes, or oyster castles [8][9][10][11][12], limestone materials, such as limestone marl, aggregates, cobbles, or siliceous limestone [10,[12][13][14][15], natural fiber-based materials, such as jute, burlap ribbon, or coconut coir [11,16], and plastic-based materials, such as Naltex™ mesh bags or Vexar™ aquaculture mesh [4,17,18]. Many of these approaches utilize recycled oyster shells in the restoration, while others employ alternative substrates for oyster colonization or planting [19].…”

“…Even restoration products that are not entirely plastic-based (e.g., rock, metal, and natural fibers) are rarely able to completely exclude plastics. Rather, small amounts of plastics are still incorporated in the form of cable ties, protective coatings, or mesh bags (e.g., [8,11,28]). In 2010, an estimated 5-13 million metric tons of plastic debris entered Earth's oceans [29]; this included both primary (those produced at the microplastic size range) and secondary (those resulting from the solar, thermal, and mechanical breakdown of larger plastics) microplastics [30].…”

Oyster reef restoration efforts increasingly consider not only oyster recruitment, but also the recovery of ecological functions and the prevention of deploying harmful plastics. This study investigated the efficacy of a biodegradable plastic-alternative, BESE-elements®, in supporting oyster reef restoration in east-central Florida (USA) with consideration for how this material also influences biogeochemistry. Four experiments (two laboratory, two field-based) were conducted to evaluate the ability of BESE to serve as a microbial substrate, release nutrients, support oyster recruitment and the development of sediment biogeochemical properties on restored reefs, and degrade under field conditions. The results indicated BESE is as successful as traditional plastic in supporting initial reef development. In the lab, BESE accelerated short-term (10-day) sediment respiration rates 14-fold and released dissolved organic carbon, soluble reactive phosphorus, and nitrate to the surface water (71,156, 1980, and 87% increase, respectively) relative to without BESE, but these effects did not translate into measurable changes in reef sediment nutrient pools under field conditions. BESE lost 7–12% mass in the first year, resulting in a half-life of 4.4–6.7 years. Restoration practitioners should evaluate the biogeochemical properties of biodegradable materials prior to large-scale deployment and consider the fate of the restoration effort once the material degrades.

The implementation of nature-based solutions (NbS), including living shorelines, to mitigate estuarine habitat loss is increasing at a pace exceeding the evaluation of their long-term success. Constructed oyster reefs (CORs) made of shell, concrete, stone, and other materials are one living shoreline tactic that is widely utilized, yet few studies have been conducted to understand the development of CORs within the context of both physical and ecological parameters over longer time scales (4 + years). A COR-based living shoreline project at the Gandy’s Beach Preserve (GBP) in Delaware Bay, NJ, USA, had dual goals of coastal protection and habitat provisioning, which prompted the development of a goal-driven monitoring framework to track project objectives. Methods were developed to quantify the following multi-disciplinary metrics over 7 years: elevations of CORs, waves (height, period, and direction), shoreline elevations, change in extent of vegetation patches, oyster density and size, nekton richness and community composition, and horseshoe crab impingement. The CORs met most of their habitat provisioning objectives as they were colonized by a multi-generational population of shellfish and created habitat for nekton, while posing negligible hazards to horseshoe crabs. However, none of the coastal protection objectives was fully achieved including material stability, wave attenuation, and sediment elevation increase. Results highlight the value of longer-term monitoring to understand performance and the need to match the scale and type of NbS tactic(s) with both the scale of the landscape and the site-specific hydrodynamic conditions to meet project goals.
