Changes in plant cover and productivity are important in driving Arctic soil carbon dynamics and sequestration, especially in peatlands. Warming trends in the Arctic are known to have resulted in changes in plant productivity, extent and community composition, but more data are still needed to improve understanding of the complex controls and processes involved.
I summarise some recent work looking at changes in Arctic peatland productivity since 1985, using Landsat satellite data, and present results of productivity response to seasonal climate drivers.
