Abstract

Three plantations of knobcone X Monterey pine hybrids were established on marginal timber sites at elevations of 671 m.(2,200 ft.) to 991 m. (3,200 ft.) in northern California in 1964. After 3 years, the hybrids appear more promising than either parent species. Damage from snow and windthrow suggests high risk of storm damage to hybrids planted at higher elevations.
