In 1992 severe flooding and subsequent cyclone were thought to be a major cause for seagrass dieback in the Great Sandy Straits Marine Park due to the resultant turbidity (suspended sediments) in the water. The turbidity restricted the amount of light getting through to the seagrasses preventing photosynthesis - critical to the biology of seagrasses and eventually leading to a dieback of seagrasses in the area. The following excerpts from an ABC Landline program produced in 1994 cover a range of seagrass issues from research, impact of fishing and recovery of seagrass meadows subsequent to the major flood event.
