Variation Between Individuals of the Same Species

Individual trees of the same species may vary considerably in decay resistance (45). In a rangewide study of the decay resistance of Juglans nigra, individual trees from the same site varied significantly in decay resistance (21). This variation is attributed mainly to genetic variability. Similarities in heartwood decay resistance between trees collected at different sites suggest that site is not a major fac-
