Expansion of shrubs in Pan Arctic ecosystems shrubification is among the most conspicuous and pervasive vegetation changes being observed in permafrost landscapes and is expected to continue in the future Across the Low Arctic, permafrost and active layer disturbances frequently are “ of rapid shrub increase, and patches of tall shrub vegetation can serve as bioindicators of past disturbances In this work, we apply convolutional neural networks ( in a pilot study to map changes in tall shrub cover in very high spatial resolution 1 m) satellite image pairs acquired in 2003 and 2015 over a Low Arctic ecotone in northwestern Siberia.
