Which species returned explained little about restored ecosystem functioning
At recovering sites, species composition explained only 2% of differences in ecosystem functions. The relationship was stronger for biomass and structure.
The study, in plain language
When examining a restored site, counting which species have returned is one way to measure progress. But an ecosystem also produces biomass, supports communities, and performs other functions. A team brought together studies from different continents to compare these two signals: which species were present and how well the site functioned.
At recovering sites, species composition explained only a small share of the differences in functions overall. The relationship was stronger for biomass and community structure than for other functions. The analysis suggests that functions and species do not necessarily recover at the same pace.
The key idea
The return of plant species says little about how much ecosystem functioning has returned, although the relationship was stronger for biomass and structure.
Something to think about
If you are following a restoration project, ask what is measured besides which species have returned: how much biomass is there, and which ecosystem functions have recovered?
