United States, National Ocean Service., Office of National Marine Sanctuaries

"In this report, the status and trends of resource condition are evaluated across the National Marine Sanctuary System (system). Among the many pressures on the natural and archaeological resources in the system, a number stand out: marine debris entanglement, trapping and ingestion, loss of biodiversity, wildlife disturbance, ship strikes and water quality, to name a few. Sanctuaries report changes in key species, which warrant special attention because of their integral role in a balanced ecosystem. Most have documented troubling invasions by non-indigenous species that can displace native species, disrupt ecosystems and damage fisheries. Many present concerns about the effects of tourism, visitation and coastal development, which can cause intentional and unintentional impacts to sanctuary resources"--Report in short.
