\u2014 A Subaqueous Soil Interpretation\n\nThe Northern quahog (Mercenaria mercenaria), commonly called the hard clam, is a species of great ecological, economic, and cultural importance. Hard clams are found in intertidal and subtidal areas from Nova Scotia, Canada to Florida. A similar species, the Southern quahog (Mercenaria campechiensis), lives in coastal waters from North Carolina south to Florida and Texas. Throughout their ranges, these hard clam species support extensive commercial aquaculture farming and recreational harvest activities.\n\nHard clams have thick shells, a violet interior border, and short siphons. The violet-colored part of the shell was fashioned into wampum by Native Americans for use as money or jewelry, hence the Latin name Mercenaria. Hard clams are the most commonly cultured of the bivalve species. Clams are an infaunal species (living in the sediment or soil). It uses a strong muscular foot to burrow into sediment (soil) and then extends siphons to the sediment-water interface allowing it to filter feed phytoplankton from the water.\n\nPurpose: Hard clams serve as biological indicators of changing environmental conditions because adult clams are sedentary. Hard clams do not migrate, so any disturbance may cause long-term population effects. While conservation and protection of existing hard clam habitat is the best strategy for addressing this problem, restoring areas that supported hard clams in the past is a valuable management measure.\n\nThis soil interpretation is intended to help identify sites with appropriate soil (substrate) types for targeted hard clam habitat restoration.\n\nSoil Rating Classes:\nHigh Suitability: Soils in this rating class have a high potential for establishing successful hard clam habitat because they have the best soil properties or characteristics.\n\nModerate Suitability: Soils in this rating class have a moderate potential for successful hard clam habitat establishment due to one limiting soil property or characteristic such as soil texture or electrical conductivity.\n\nLow Suitability: Soils in this rating class have a low potential for successful hard clam habitat establishment due to multiple limiting soil properties or characteristics.\n\nNot Suitable: Soils in this rating class are not suitable for oyster restoration because they are freshwater subaqueous soils that lack the appropriate salinity levels necessary for hard clams.\n\nNot Rated: These soils or miscellaneous areas are not subaqueous soils; therefore, they are not rated as this soil interpretation should only take into consideration subaqueous and submerged soils.

Often concentrated on oyster bars, beds, or rocks, which are located in waterways with firm bottom areas, oysters attach to one another forming dense reefs that provide habitat for many fish and invertebrates.\n\nLike all oysters, the Eastern oyster is a filter feeder. They draw in water and filter out plankton and detritus to digest, then discharge unwanted food items and particulate matter, thus cleaning the water around them. One oyster can filter more than 50 gallons of water in 24 hours. Oyster beds have an estimated 50 times the surface area of an equally sized flat bottom and attract a high concentration of larger predators looking for food (Eastern Oyster, 2016).\nOysters are considered a keystone species in most estuaries along the Atlantic and Gulf coasts. Grabowski and Peterson (2007) recognized seven ecosystem services provided by Crassostrea virginica habitats. They are: (1) oyster production; (2) water filtration and concentration of pseudofeces; (3) provision of habitat for epibenthic invertebrates; (4) nutrient sequestration; (5) augmented fish production; (6) stabilization of adjacent habitats and shoreline; and (7) diversification of the landscape and ecosystem.\n\nDespite their significance, oyster reefs are one of the most threatened marine habitats on earth. In the last decade, many people have come to support oyster restoration efforts for the purposes of conservation and provision of ecosystem services. Construction of oyster reefs is supported as an avenue for protecting biodiversity, regulating nutrients in estuaries through water filtration, protecting shorelines from erosion, and providing habitat for many estuarine species.\n\nThis soil interpretation is intended to help identify sites with appropriate soil (substrate) types for targeted oyster habitat restoration.\n\nSoil Rating Classes:\n\nHigh Suitability: Soils in this rating class have a high potential for successful oyster restoration because they have the best soil properties or characteristics for a successful establishment of an oyster reef.\n\nModerate Suitability: Soils in this rating class have a moderate potential for successful oyster restoration due to one or more limiting soil properties or characteristics such as soil texture or electrical conductivity.\n\nLow Suitability: Soils in this rating class have a low potential for successful oyster restoration due to multiple limiting soil properties or characteristics.\n\nNot Suitable: Soils in this rating class are not suitable for oyster restoration because they are freshwater subaqueous soils that lack the appropriate salinity levels necessary to establish and grow oysters.\n\nNot Rated: These soils or miscellaneous areas are not subaqueous soils; therefore, they are not rated as this soil interpretation should only take into consideration subaqueous and submerged soils.\n\nReferences\n\nEastern Oyster. http://www.ereferencedesk.com/resources/state-gemstone/louisiana-gemstone.html (accessed May 2016).\n\nGrabowski, J.H., and C.H.
