Ecological Succession: The Temporal Pattern of Late Successional Tree Establishment in a Michigan Old-Field
Harbeck, Amy L.
MetadataShow full item record
The ages of late successional trees were estimated in a Michigan old-field in order to test Egler's (1954) hypothesis of old-field plant succession. Trees appeared to have established according to Clements' traditional theory of plant succession. Trees invaded a set of fifteen-year-old plots eight years after abandonment and a set of ten-year-old plots after five years. Possible factors involved in the observed pattern of tree establishment are discussed.
