I agree it is not typical of an adult wombat but it is not typical of the other likely source either - a large EGK. So which is it?
Is there actually more than one wombat in the reserve and this is from a juvenile/sub-adult? Or did the usual wombat dine on something a bit different for once (they are said to eat strictly grass but probably take the occasional dicot as well) and anyway, grass varies in water and fibre content. I wonder if there might have been other wombat signs nearby too, like scratchings or hair? Anyway there have been other wombat records quite close to this point recently.
DonFletcher There is a huge amount of large pellets in the drainage ditch close to where it enters > 0.5 m diameter stormwater pipe. I discovered that today but I didn't have my phone with me; I will take photos with measuring tape later today. I'm pretty sure wombat not EGK - Im quite familiar with EGK pellets :-) We replaced a lot of exotics with natives in the area including native grass on top and Carex appressa at the bottom of the ditch... I observe heavy grazing of dicots (for instance Dianella revoluta) which we planted along the edge but I can't say by which herbivore; there are lots of rabbits around.
When I was a uni student I once watched one of the keen cavers successfully squeeze through a 10" (0.25 m) concrete culvert pipe. It was amazing and almost scary to watch. So Waltraud you would easily scurry into and out of a 0.5m burrow if you wanted to get a photo and become more closely acquainted with the wombie itself, not just its droppings.
