Abstract

Seagrass beds are an essential part of estuaries and shallow coastal waters that provide many services and support to the ecosystem. They serve as nurseries for marine life, decrease shoreline erosion and increase sediment stabilization. </br>Disturbances to seagrass beds can be natural such as stingray pits, or they can be anthropogenic such as propeller scars. </br>Stingray pits are a result of bioturbation from the stingray feeding on benthic organisms which causes a deep depression in the seagrass beds, but also can release trapped nutrients from the sediment. </br>Natural disturbances are expected to be more abundant, and to occur more frequently in seagrass beds.
