Overcoming barriers to build partnerships for managing plant invasions under global change

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Non‐native plant invasions are a cross‐boundary conservation challenge, requiring coordinated management and policy responses underpinned by science. Global change is expected to exacerbate this challenge by changing abiotic and biotic drivers of invasive plant distribution, abundance, and impact. Current approaches may no longer be effective,
