Course Outline

Submersed aquatic vegetation (SAV) are underwater grasses often found in shallow (usually less than 6 feet), tidal, and non-tidal areas.

  • SAV are an important habitat for fish and shellfish and are a food source for several waterfowl species.
  • SAV protect shorelines and bottoms by adding oxygen to the water and reducing wave energy.
  • SAV beds can be scarred by propellers of small vessels or by larger craft if they run aground. Recovery from this scarring can take years.
  • Avoid damaging SAV when operating your vessel in shallow areas, particularly at low tide.
