Figure 4: Geographic variation in sensitivity to N and S deposition.
Shown are the percent of species that decrease (a) or increase (c) in probability of occurrence with increasing N deposition, and decrease (b) or increase (d) with increasing S deposition. Plots were aggregated within a 12 × 12 km grid cell and unique species were only counted once if they were potentially vulnerable anywhere in the cell. Note the color ramps are flipped between decreasers and increasers, with hotter colors denoting negative effects (i.e., more decreasers and fewer increasers, most species assessed were native).
