Abstract
Drifting macrophytes consist of many species of seagrass and algae (Baring et al. 2014). During storms or large swell events, seagrass and algae are often ripped from the seafloor by hydrodynamic forcing and either float to the surface and drift, or tumble along the seafloor (Baring et al. 2014; NACC 2014a). In South West Australia, this hydrodynamic forcing typically occurs during storm events during the period late autumn to early spring (NACC 2014a). In the swash zone of sandy beaches, drifting macrophytes are pushed into the surf zone by wave, tidal and current forcing where they form dense accumulations before being washed ashore (Crawley & Hyndes 2007; Crawley et al. 2009). Drifting macrophytes may eventually be stranded on beaches and form large piles of beach-cast wrack which can then re-enter the surf zone with subsequent high tides (Ince et al. 2007)...
