Although I haven't tried this species, the local D. planchonii has large, if
thin, seeds (few-several mm long) and required no special treatment.

good technique to try. Slow-burning causes damage to native plants due
to the steam and prolonged heat generated. The typical "safe" bushfire
is fast, causing a short, intense heat period, ash but little steam (the
fuel for this type of fire is dry, so burns readily) which, although
causing damage, leaves the growing regions of the plants (and seeds)
unharmed as well as producing the fertilizing ashbed to stimulate
growth. If you have enough seed, your best bet would be to try a few
different methods (ie. "control", burn dry straw on top of another,
bury seed, surface sow seed, etc. etc.) in the hope that at least one
will be sucessful...
