Nitrogen deposition and plant diversity

Researchers report that a century of rising nitrogen deposition may have led to a loss of plant species at 24% of more than 15,000 sites across the United States, and that grasslands, shrublands, open woodlands, and regions with acidic soil were particularly susceptible to a loss of plant species from nitrogen deposition, findings that could help establish air quality standards and conservation priorities, according to the authors. - See at PNAS.org
