It's bushfelt region, which is dry and prone to a lot of fires, as so what these trees have done is, if you can imagine that this is the crown of the tree, and that this is ground level, imagine that the whole thing, that whole bulk of the tree, migrated underground, and you just have those leaves peeping up above the surface.
ブッシュフェルト地方は 乾燥し火事が起きやすい場所です これらの木が何をしているかというと ここが木の最上部で こちらが地面だとして 木の全体が 地中に 移り住んでしまい これらの葉だけが地表に現れているのです
