- •
In 11 years of hot drought, perennial grass basal cover and shrub cover declined.
- •
Several species of C4 perennial grass showed die-offs but mortality was patchy.
- •
Declines were associated with low rainfall in January–June “extended spring” season.
- •
Soil and topography mediated how drought affected plant and ground cover.
- •
Despite drought impacts, ground cover and grass diversity persisted.
