Evidence: Peer-reviewed restoration cohort experiment
Geography: Kansas, USA
System: Restored tallgrass prairie

WHAT THE EVIDENCE SAYS

Planting cohorts started every two years; early precipitation differences were important predictors of community dissimilarity into year three, while forb and C4 grass cover responded differently to establishment temperature and rainfall.

WHY IT MATTERS / OUR READ

Restoration records need the climate experienced by a seed mix, not only the seed label and later management. Establishment-season weather can create lasting trajectories.

CAVEATS / UNCERTAINTY

One region and a limited early-establishment horizon; responses do not yield transferable rainfall thresholds.
