open access: yesNew Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments.

‘Greening’ is often depicted as an inherently benevolent practice, turning arid stretches of land into arable and fertile plots. However, by considering a longer history of place and taking archival records into account, such transformations are rendered more complex and, often, more fraught.
