Title: Projecting the vegetation response to climatic change in the North American Central Grasslands Region

Abstract

An interdisciplinary modeling effort is underway in which high-resolution climate change projections will drive the Mapped Atmosphere-Plant-Soil System (MAPSS) to simulate vegetation change in the Central Grasslands Region. MAPSS calculates a complete site water balance and solves for the leaf area (LAI) of both woody and grass lifeforms in full competition for both light and water. Fire is a necessary constraint on simulated shrub LAI throughout much of the grasslands region, and incorporation of weather variability is critical for obtaining accurate tree/grass LAI ratios in the Prairie Peninsula. Initial estimates of the potential impact of climatic change include significant changes in both lifeform LAI and the distribution of subformation vegetation types, but the magnitude and even the direction of change varies with the climate scenario and with assumptions concerning wind speed and plant water-use efficiency.
