Plant Succession Trees play a major role in creating terrestrial plant cover when conditions develop to the point where some bare-ground and soil is present. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science. These changes include accumulation of organic matter in litter or humic layer, alteration of soil nutrients, or change in the pH of soil due to the plants growing there.

However, like many of the ecosystems on Earth, the gra Because of residual fertility and pre-existing organisms, community change in early stages of secondary succession can be relatively rapid. Scoring Guide. For example, species diversity almost necessarily increases during early succession as new species arrive, but may decline in later succession as competition eliminates opportunistic species and leads to dominance by locally superior competitors. Wildlife populations are also a significant contributor of soil nutrients, with feces being rich in both nitrogen and phosphorus. The Bulletin of the Torrey Botanical Club, Michael G.
