The Vegetation of the Inland Sand Deposits of Illinois

Abstract

In the rapid development of ecological and phytogeographical knowledge during the past few decades, the vegetation of sand deposits has been the subject of especially frequent and detailed study. At least three reasons may be mentioned why this type of vegetation has received particular attention. First, sand deposits are usually well developed and form dune complexes of greater or less extent along the shores of the ocean or the larger inland lakes, and in many cases are convenient places for vacation trips. Secondly, the vegetation on sand is usually open and easily studied, and the dynamic nature of the environment is emphasized. For this reason the interrelations
of plant and environment are more easily observed and offer attractive fields for study. Thirdly, sand areas are usually infertile in
comparison with their surroundings. They are accordingly frequently left uncultivated and constitute temporary natural preserves,
in which the original types of vegetation persist and are available for study.
