This is expected to change as species expand their range limits upwards to fill their climatic niches and respond to ongoing anthropogenic disturbances. Yet, whether and how quickly these changes are happening has only been assessed in a few isolated cases. Starting in 2007, we conducted repeated surveys of non-native plant distributions along mountain roads in 11 regions from 5 continents. We show that over a 5- to 10-year period, the number of non-native species increased on average by approximately 16% per decade across regions. The direction and magnitude of upper range limit shifts depended on elevation across all regions. Supported by a null-model approach accounting for range changes expected by chance alone, we found greater than expected upward shifts at lower/mid elevations in at least seven regions. After accounting for elevation dependence, significant average upward shifts were detected in a further three regions (revealing evidence for upward shifts in 10 of 11 regions). Together, our results show that mountain environments are becoming increasingly exposed to biological invasions, emphasizing the need to monitor and prevent potential biosecurity issues emerging in high-elevation ecosystems.

Spread of non-native plant species into mountains : now is the time to act / Keith L McDougall in Mountain Forum Bulletin, (07/2009) 

Public Citation [article]  inMountain Forum Bulletin > (07/2009) . - 23-25 Titre : Spread of non-native plant species into mountains : now is the time to act Type de document : Électronique Auteurs : Keith L McDougall ; Sylvia Haider ; Tim Seipel ; Christoph Kueffer ; MIREN Consortium Année de publication : 2009 Article en page(s) : 23-25 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Thématique] Revégétalisation Résumé : Mountains are hotspots for biodiversity and of great importance to human societies. The worldwide placement of mountain areas in conservation reserves is recognition of their value. Managers have to remain vigilant to protect mountain ecosystems from future threats. One such threat is invasive, non-native plants. Invasive plants alter plant communities, affect grazing lands and homogenise the world’s flora. Mountain areas have not been as intensely affected by plant invasions as low elevations because of harsh climatic conditions, isolation and limited human pressure. The relative resistance of mountain ecosystems to plant invasions may be transient, however, in light of ongoing global change (e.g. climate change, expansion of human pressures). Unique mountain flora, fauna and habitats may become increasingly susceptible to invasions.
