Environmental factors contribute to acorn quality: Elevation, on- or off-tree collection influence the viability of blue oak acorns

Abstract

Concern about the regeneration of California's native oaks has inspired several investigations that indicate acorn quality is one of many factors affecting regeneration. A survey conducted in Kern County in 7990 indicates that elevation influences blue oak and valley oak acorn quality; location with regard to water drainage is another factor for blue oak acorns.
