Summary

Story summary

A Swiss-led team finds that the duration of an invader's presence significantly reduces native plant diversity, with longer invasions causing greater losses.
The study, led by Professor Madhav P. Thakur, notes some soil properties stabilize, but native diversity keeps declining.
The researchers link invasions to higher greenhouse gas emissions, implying management could help address climate change.
The findings, published in Science, stress early intervention and adaptive monitoring to protect ecosystems.
