Definition Areas dominated by canopy-forming algae that have complex growth forms with holdfasts and well-defined stipes and blades. Canopy forming algae are distinguished from other types of macroalgae, in that they often reach heights of several meters or greater. Their presence alters water energy patterns and provides shelter for other marine organisms. Kelp beds are an example of canopy forming algal communities (Figure 8.14).
