Put a frog on it ...

So may people today would rid themselves of their daily angst and frustrations if they just walked away from their computers or cars and dug in a frog pond.

Yes, to paraphrase Portlandia, put a frog on it.

I dug a pond in a few months ago. A tiny pond crafted from an old shell-shaped kiddies' sandpit, lined with the cuttings off an old inflatable kayak, and filled with mud, rocks and a selection of plants gleaned from the dredging of the local drainage canal down at a nearby park. So, there's the flatsedge, Cyperus eragrostis, some weedy Bacopa monnieri (all, may I add, for sale at local aquarium stores), and I bought the edible culinary herb, Persicaria odorata and some Ornduffia parnassifolia to add colour and spice.  Because it's nice to have a little watery green feature in a backyard of otherwise grey sands of Bassendean.
Of course, this was an empty pond, bereft of frogs and waiting for Them To Come. Quite a few frogs do wander the streets of Bayswater. Motorbike frogs (Litorea moorei) and banjo frogs (Limnodynastes dorsalis) in particular stretch their legs on many an occasion and have found themselves in our yards. So usually it was a matter of waiting for a wandering frog to take up residence. In the interim, I did pop in a couple of white mountain cloud minnows (Tanichthys albonubes, an exotic species available on the day) in order to keep the mosquitoes down.

And that was that ..................       until the call came out in late November for homes for needy homeless tadpoles. A local was cleaning his pool for summer and found a batch of tadpoles needing rehoming in the local area (within a 5km radius). The local environment centre took these on and from there we picked up our new tadpoles. They took to the pond with gusto - or more just plain relief after a few miserable weeks in a deep, hot plastic tub. The addition of tasty lemna  made it perfect.

A tiny new froglet emerges.

And within a  few weeks, new froglets emerged and took up residence in the ponds - yes, we bought a pre-fab fiberglass pond to accommodate the growing frog family and because the original clamshell sand pit appeared to have a slow leak.  And this time we popped in six western pygmy perches.

And then there was the need for a second pond as the number of emerging frogs swelled. And so now we are humble slaves to our new, free-range pets, planting more sedges and shrubs, topping up the ponds, putting in a small solar light to attract night insects. They feed themselves, although I still scatter in fish granules for the tadpoles and fish, and I do trust that they are making a dent in the local slater, mosquito and grasshopper population. As a reward, I get prime frog viewing and some pest control.

Turtle frogs - just bizarre

So ugly they're beautiful  sorta cute...

Myobatrachus gouldii

It has been a dry dry winter and spring, except some decent rainfall last night brought out the call that turtle frogs would be about.

I've never seen one before, and thought that they were impossible difficult to see, and only the most dedicated herp freaks would ever have a prime viewing experience.

But no - they're far more common than I had thought, and last night was the night to see them crawling around on the surface, calling out to the ladies, looking for a mate to spend their summer with deep down in a burrow of love.

The live in SW Western Australia, on sandy soils - hence they do well on the Swan Coastal Plain - a place of exceptional sandyness. It would appears that a number of significant bushland reserves, like Whiteman Park, Bold Park and Kings Park, have sizeable populations of turtle frogs lurking in these sandy soils. They spend most of the lives nudging their way face first in the sand, burrowing away in a fossorial manner, eating termites. Termites!

But there are a very few occasions when the critters come to the sandy surface, and  this is usually spring-summer on the first night of/after the first heavy rainfall.

So - spring rains mean pairing for the frogs, followed by a summer spent together in a burrow, summer mating and egg laying, and then these eggs develop directly into froglets. That's pretty amazing.

The call is a deep, throaty "murrrp" and there were .. well.. from the sounds of it.. 'undreds of 'em.  And they're tiny - only about 2 -3 cm long (SVL). They can be hard to spot, but when you finally triangulate their location and peer around - there they are! On the soil surface, looking a bit like a cross between a marri nut and a strawberry bubblegum bubble.Or in a burrow entrace or depression in the sand.

No bulgy froggy eyes for these guys - they have tiny, deeply inset eyes like a microbat or mole, apparently covered a protective membrane. They have a saggy, oversized skin which appears to inflate like a bubblegum bubble. They're also pinkish - which takes their resemblance to a bubblegum bubble even more.. And chunky arms. They have chunky arms for digging face first through sand.

That's great - thanks to those who alerted me to finding this amazing frog, and I'll keep an ear out for them again next time we get the decent rains...
