Evidence: Peer-reviewed randomized restoration experiment
Geography: Florida Panhandle, USA
System: Wet prairie / longleaf pine wetland

WHAT THE EVIDENCE SAYS

Twelve treatments combined cutting, organic-layer scraping, diaspore transfer and prescribed fire. Mechanical clearing alone produced initial reduction followed by strong woody rebound; scraping reinforced persistence, while propagule transfer increased forbs.

WHY IT MATTERS / OUR READ

Wetland recovery needs attention to substrate and seed limitation as well as woody stems. More complex treatments moved vegetation closer to references, but did not fully restore them.

CAVEATS / UNCERTAINTY

Soil scraping is intrusive and site-dependent; vegetation remained different from reference wetlands, and ecological collateral effects matter.
