Evidence

Peer-reviewed

Geography

Controlled wetland-plant experiments, China

System

Wetland invasion; biochar and soil amendments

## WHAT THE EVIDENCE SAYS

Researchers applied biochar from two invasive plants at different rates and with or without nitrogen while monitoring the invasive Flaveria bidentis. Several biochar treatments increased invasive growth, while certain amendment combinations reduced it.

## WHY IT MATTERS / OUR READ

A circular-material intervention can change ecological incentives in unexpected ways. Biomass reuse and soil-carbon claims must be tested against site-specific invasive growth responses.

## CAVEATS / UNCERTAINTY

Microcosm results cannot establish long-term field invasion, net climate benefits or universal effects across biochars, soil types and receiving habitats.
