Description: This publication reports the results of a preliminary survey listing 527 forest-tree plantations in the western United States and Canada. Of these, 250 involve families of known parentage, 131 provenance-test material, 87 clonal material, and 59 interspecific hybrids. The report is intended (1) to serve forest researchers in locating genetic material relevant to their work, and (2) to facilitate an assessment of regional forest-gene resources. A list of agencies, a species index, a brief discussion of survey results, and recommendations complete the report.
Notes: Includes bibliographical references (p. 16).
