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.
