Description: Christmas tree growers in California have asked geneticists to help improve the characteristics of the - wild species they are cultivating. The preferred Christmas trees of California are Shasta red fir (Abies magnifica A. Murr.), white fir (A. concolor (Gord. & Glend.) Lindl.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). The individuals of these species are quite diverse. Trees of all shapes, sizes, and needle characteristics can be found in young plantations or natural stands. Unique combinations of these characters are found in some trees. Many outstanding types could be commercially exploited if their characteristics proved to be genetically determined.
Keywords: accident costs, hazard control costs, forest safety, recreation budget, accident prevention, I-azard control priorities, tree defect.
