Algae is a prime example of a pioneer species that would be found where a glacier has retreated, because the glacial retreat allows for its growth. This process is called succession and usually starts with lichen, an relative of algae. Lichen grows on bare rock which is left behind. Afterwards, acids produced in this environment cause dirt and soil to be created.

In coastal areas, wind moves sand, blowing away or engulfing the soil, and eventually creating sand dunes

fomenos

In physical geography, a dune is a hill of loose sand built by wind or the flow of water. Dunes occur in different shapes and sizes, formed by interaction with the flow of air or water. Most kinds of dunes are longer on the windward side where the sand is pushed up the dune and have a shorter "slip face" in the lee of the wind. The valley or trough between dunes is called a slack. A "dune field" is an area covered by extensive sand dunes. Dunes occur, for example, in some deserts and along some coasts.
