Description: This data was derived as part of the Overall Assessment of the State of Nearshore Waters. The supply, transport and deposition of sediment are natural processes that form and maintain coastal features like wetlands and beaches. Artificial shore perpendicular structures (littoral barriers) can disrupt natural movements of sediment and affect the integrity of ecosystems. Littoral barriers is assessed by counting the number of littoral barriers (>100 m in length) in a Regional Unit. Littoral barriers were digitized using best available imagery, at a scale of approximately 1:2,000.A littoral barrier is a shore perpendicular structure that, for purposes of the Overall Assessment of the State of Nearshore Waters, is at least 100 metres in length.In Regional Units where littoral drift is not a dominant coastal process, the measure not apply and is tagged as "N/A'.Low Stress: 0 littoral barriersModerate Stress: 1 littoral barrierHigh Stress: >1 littoral barrier
