In this FIDO Backgrounder, rhyme describes the nexus between K’Gari’s soil formation and vegetation types as it evolves from dune systems on K’Gari’s east coast (#1) to the nutrient deficient system on the west coast (#6).

dune system 1
Dune System One/ The soil has just begun/ With A and B little or none/ And the ecosystem is underdone.
dune system 2
Dune System Two/ B’s got a darker hue/ Eucalypts are now in view/ But soil development has much to do.
dune system 4
Dune System Three/ Has many a Blackbutt tree/ Richer horizon B and nutrients the key/ The forest resulting is grand to see.
dune system 4 rainforest
Dune System Four/ Gets the highest score/ B horizon is further below the floor/ It supports rainforests and much more.
dune system 5
Dune System Five/ The ecosystems losing its drive/ Tall trees shrink just to stay alive/ Roots can’t reach the B, though they strive.
dune system 6
Dune System Six/ The ecosystem is in a fix/ Tall trees have turned into Mallee sticks/ Reaching deeper nutrients defies all tricks.
