NOAA explains that “SAV (submerged aquatic vegetation) is a term used for rooted aquatic plants that grow completely underwater. These plants occur in both freshwater and saltwater but in estuaries, where fresh and saltwater mix together, they can be an especially important habitat for fish, crabs, and other aquatic organisms.” Read more about SAV here: SAV background.
