Each year, several million seedlings are outplanted. However, many of those do not survive or grow well. Often, mortality and poor field performance are attributed to poor seedling stock quality. Each year's crop can have a high degree of variability due to a variety of factors. It is important to establish and measure quality criterion so as to create a basis for nursery and buyer understanding of crop quality at lifting and after outplanting.

Oregon State University offers a regional seedling quality evaluation service. Not only does this provide an important resource for nursery and reforestation managers, it also generates a regional database on annual seedling quality trends (See Development of Acclimation). In addition, it creates an opportunity to research relationships between quality measurements and outplanting performance and to examine species and stocktypes for which there are limited quality data.
