For example, arbuscular mycorrhizal fungi, which can form mutualistic interactions with plants, are known to play an important role in plant survival and growth, but are generally absent from early stages of primary succession (Greipsson and El-Mayas, 2000).
Soil organisms are of crucial importance in primary succession, the unassisted processes of natural decolonisation deliver functional, fully developed ecosystems in spoil heaps [16].
Ecological processes can be observed during primary succession on newly exposed substrates, and as shifts in the locations and characteristics of wetlands, of treelines, and in the relative abundances of woody plants.

Her studies indicate that in the southeastern United States, willows and other primary succession trees growing along streambanks have lower tensile strength levels.
Studies of vegetational development (Eggler, 1959, 1963; Beaman, 1960; Rejmanek et al., 1982; Gimenez de Ascarate et al., 1997) have shown an increase over time in species richness and plant cover as either primary succession (on lava flows and the cinder cone) or secondary succession (on forested areas affected by deposition of volcanic ash) progressed.
When succession occurs in a new or pristine habitat or in one that has not previously had a similar community occurring there, it is called primary succession. The classic example of primary succession is the normal transition of a pond or a bog and then to woodland as it slowly fills with silt and organic material.
There he earned his Master of Science degree with Bill Weber by working up plant collections he had made at the Knob Lake subarctic field station of McGill University, Schefferville, Quebec, followed by a doctorate with John Marr on primary succession on the Muldrow Glacier foreland, Denali National Park.
During the course of primary succession, organisms settle on a new area resulting from changing ecological conditions, ecosystem destruction, or the addition of new land.
