Predicting spring green-up across diverse North American grasslands

Existing models of grassland phenology poorly predict green-up. Inclusion of precipitation, in addition to temperature, resulted in significantly better model results, although different thresholds apply across different climate regions.

Productivity of North American grasslands is increased under future climate scenarios despite rising aridity

We explore the potential responses of North American grasslands to climate change using a new, data-informed vegetation–hydrological model, a network of high-frequency ground observations across a wide range of grassland ecosystems and CMIP5 climate projections.
