In recent decades, a worldwide trend of increasing woody plant abundance in grasslands and savannas has been reported. This proliferation of trees and shrubs move affects livestock production, wildlife habitat, water availability. At the same time their presence changes the way the ecosystem processes carbon and nitrogen, two important elements linked to climate change. SNR professor Steve Archer is interested in understanding how carbon and nitrogen stocks in ecosystems change as the systems shift from grassland to shrubland.
