Climate change is causing plant species in mountains worldwide to shift their elevational ranges, complicating efforts to monitor these changes due to varying sampling methods.
The Mountain Invasion Research Network (MIREN) developed a standardized protocol to assess native and non-native plant distributions along elevation gradients over time, using surveys conducted every five years at specific sites.
Initial results show unique elevational patterns for native plant richness and a global decline in non-native species, highlighting disturbed areas like road edges as hotspots for plant invasions, emphasizing the need for more global studies to guide conservation efforts.
