Abstract

Establishment of tree seedlings in early stages of old-field succession on soil derived from Triassic red shales of the piedmont of New Jersey is reported. The studies were made at the Hutcheson Memorial Forest preserve. On fields abandoned from cultivation at two-year intervals starting with 1958 permanent quadrats were established and sampled annually. Results showed that, as a rule, tree seedlings do not become established during the first year but begin to appear the second year, with new ones continuing to appear in successive years. Mortality of previously established individuals is also common during the early stages of succession. During early successional stages, when much bare soil is exposed, heaving due to freeze-thaw cycles in winter is one of the major influences in hindering early establishment of tree seedlings.
