Introduction

Most woody plant species produce good seed crops every 2 to 10 years, depending on the species, genetic variation within the species, climatic variables, and location. Because of irregularities in seed crop production, a supply of seed must be maintained to meet the needs for seed between good seed crops. Generally, each national forest should maintain enough seed to meet artificial reforestation and restoration needs for 10 years. Seeds banks may be managed by individual forests, by seed or breeding zones that encourage seed to be shared across forests, or by other administrative boundaries when seed guidelines allow such transfers.

The information included in this Web site is intended to supplement local direction provided in Regional Handbooks or other direction. The focus of this section is on planning and carrying out the collection. Managing the seed bank, seed extraction practices, and need for reforestation are not covered.
