We compiled six long-term datasets from western North America to test for ecosystem-dependent survival patterns of forbs and grasses. We found that life form exerts a strong influence on survival parameters and their response to temperature variation among ecosystems. The age-specific demography of herbaceous plants has implications for population modeling and research on life history evolution and senescence.
