Heavy mortality and poor growth among repeated plantings of white birches were associated with toxic conditions produced by black walnut trees. Variation in response to toxicity was observed. Lethal effects were most prominent in the immediate vicinity of residual black walnuts, but some individuals survived in these areas, suggesting differences among trees in their levels of toxin tolerance. Birch trees were larger as distance from the source of toxicity increased, indicating a relationship between growth inhibition and toxin concentrate.
