Fig. B1. Geographic distributions of temporal regression slopes between (A, B) bird species richness and NDVI (Normalized Difference Vegetation Index), (C, D) total bird abundance and NDVI and (E, F) species richness and total abundance. Left panels show all sites with positive slopes, and right panels show all sites with negative slopes.
