Fabulous Frogmore

I’m pleased that I was able to pay a visit to Frogmore Swamp this afternoon. This fabulous wetland, dominated by Cane Grass Eragrostis infecunda, is drying rapidly unlike the last time it was full over the summer of 2010/11. Back then it held water throughout 2011 and there were some interesting birds to be seen, including rarely seen migratory waders such as the Wood Sandpiper and Double-banded Plover. This afternoon the most conspicuous birds were ibis, Sacred and Australian White Ibis, along with a bevy of ducks – Grey Teal, Australian Shelduck and Black Ducks.

Frogmore Swamp is a special place in a special landscape.

  1. Thanks, as ever Geoff. Do you know anything of the hydro-geology of the Moolort Swamps – why do they hold water, what’s the subsurface geology, how do they link to aquifers? This may be beyond birds, but I was wondering, as the retained water seems so important. Cheers

    • Hi Deb – I am digging up a report which I will send you about this matter as it relates to Bell’s Swamp, at the extreme north end of the plains. While not truly part of the Moolort plains this swamp behaves in a similar manner to the likes of Frogmore and Walkers Swamps. Essentially they fill from small localised catchments – a layer of low permeability material (black goo!) has formed over many hundreds/thousands of years and traps runoff in wetter than average years. They are not directly connected to underlying aquifers, although small volumes of water might leak through. Long Swamp is a different kettle of fish – it appears to fill at least in part from groundwater recharge via the basalt cone to the north of the swamp. I’ll send this report on also. Cheers, Geoff
