In situations where protection from an open-area climate is not required, T. heterophylla regenerates naturally in the open on forest floor materials immediately after cutting. Its growth may be so vigorous that it will overgrow planted Pseudotsuga menziesii (University of British Columbia Research Forest, near Vancouver).
