Recovery of terrestrial ecosystems from long term exposure to elevated N
On this page:
This presentation discusses the processes for recovery of biogeochemical cycling, and the plant community, following long term exposure to elevated nitrogen. It draws from experimental and observational studies, and finds that: (1) natural recovery (i.e., after deposition decreases) is slower than we once expected, (2) single-factor interventions appear insufficient in grasslands and forests (though more work is needed), and (3) multi-factor interventions show promise for inducing ecosystem recovery over time scales that are relevant to management (e.g., decades).
