Effect of boat moorings on seagrass beds near Perth, Western Australia
Boat moorings have been found to produce circular scours in seagrass meadows, ranging from 3 to 300 m 2. “Cyclone” moorings (which have three anchors and a swivel) are much less damaging to seagrass meadows than “swing” moorings (with a single anchor and chain). The total area of seagrass meadow los...

2. “Cyclone” moorings (which have three anchors and a swivel) are much less damaging to seagrass meadows than “swing” moorings (with a single anchor and chain).
The total area of seagrass meadow lost due to moorings totals some 5.4 ha in the Rottnest Island, Warnbro Sound and Cockburn Sound regions of Western Australia, with most loss (3.14 ha) in the Rottnest region. While the relative area of seagrass meadow lost is small ( |
