Extended Data Fig. 2: Histograms of 2000 and 2019 endpoint effects by wood products.
From: Sensitive tree species remain at risk despite improved air quality benefits to US forests
Ridgeline histogram plots of N-influenced growth rates (a), N-influenced survival rates (b), S-influenced growth rates (c), and S-influenced survival rates (d). The upper panels display distributions of effects from deposition in 2000 and lower panels are effects from deposition in 2019. Different wood product uses are shown where B is strictly building materials, UP is unfinished wood products, UP+B is unfinished wood products and building materials, and Neither is neither of those types of wood products44.
