SOURCE-REPORTED OBSERVATIONS
Phosphorus loads by intervention
Values are seasonal area-normalized loads (g/ha). Each paired bar uses the same scale within that observation, not across analytes or studies. Lower recorded loads do not automatically establish causation.

Scientific review status
What Gaia does not claim
These are published field comparisons, not independently verified project-level treatment effects. Confounding factors, uncertainty, causal design, transferability to a specific restoration site and cost-effectiveness all require further evidence.
