The only difference is the Wallaby is a herbivore so the dung does not smell. Wild boar is an omnivore so I am not sure what aromas you might have to put up with, still plenty of fungi I would think.
Mal
Not only smell but safety aspects too, worms, various parasites and human pathogenic bacteria like Salmonella have to be contended with.
I’m not seriously thinking of looking for Wild Boar (ghosts of the forest) dung. I will leave that up to NRW and the police! Release of Wild Boar from licensed farm during burglary near Maesteg in 2014 and now seem to be breeding in the wild.
