Table 1. Summary of tree species’ relationships with N deposition.

Numbers in columns and rows indicate the number of species with a monotonically decreasing, flat, monotonically increasing, or unimodal growth or survival association with N deposition across the range of deposition exposure. The letters denote classes based on the shapes of the combined growth and survival relationships, as described in the text.
