Density independent processes
All three environmental drivers (snow, N, and temperature) influenced the density-independent growth rates of species groups with varying consistency and magnitude across treatments (Fig 2, Table S1). Drivers often had counteracting effects, reducing the benefits of enhanced resource availability (water, N, and temperature) on density-independent growth rates. In addition, rare species had very few responses to environmental drivers (Fig S7), consistent with the limited change in cover of this group over time.
