Seagrass meadows, I think, are like the frogs of the ocean. When they are flourishing, the place is going okay.
Last night we netted at the eastern end of the harbour and checked out the meadows. They offered up little yellow clusters of flowers.
At the western end of Princess Royal Harbour, an invasive algae is on the march, victualled by the town's nutrient run-off. The algae is slimy and khaki and it spreads through the shallows, smothering the sea meadows. Probably, it was introduced by ship's ballast from some exotic port, then successfully distributed in the advent of trailered dinghies. (Like us.) No flowers there.
Oyster Harbour, on the other hand, doesn't have the same problems with algae, doing away with my trailered boats hypothesis. Maybe its health is due to the estuary being fed by two fresh water rivers. The seagrass there is dusty with silt from the Kalgan and the King, brown rather than bright green, but it is thriving.
Spider crabs cultivate seagrass on their crowns. So cute, an emerald tuft growing from their heads, a ruse to disappear into the meadows.
These pictures were taken at Two People's Bay. The water is so clear, a joy after a winter in the murky inlets (though a bit frightening after weeks of an easterly onshore that rolls the swell in mountainous, sloppy deckie traps). The seagrass at Two Peoples Bay is a different species, smoky grey green rather than bright green, and I didn't see any flowers when I was there last week. See how the meadows sway and weave into rows as the currents divide them, curling them over each other like a woman's hair ... or meadows of soft, soft grass in the wind.
