The Mountain Invasion Research Network (MIREN) was established in 2005 to address the growing concern of plant invasions in mountain ecosystems. Initially, MIREN focused on understanding how non-native species spread along elevation gradients and the role of climate change and human-mediated disturbances in facilitating these invasions. Over time, its scope has expanded to include the movement of native species and broader species redistributions. Additionally, MIREN has integrated socio-ecological perspectives, considering the influence of human activities on invasion processes.MIREN has grown from a small research initiative into a globally coordinated network of scientists dedicated to studying the patterns, processes, and impacts of non-native species in high-elevation environments. By fostering international collaboration and standardizing research methodologies, the network has provided critical insights into the ecological and anthropogenic drivers of plant invasions across diverse mountain regions. One of its key contributions is the development of standardized monitoring protocols, enabling comparative studies across continents. The most widely used is the MIREN road survey (i.e., road T-transects), which has been implemented since 2006 in over 20 mountain regions across all continents except Antarctica. Through repeated resampling and the inclusion of native species, this survey has become a long-term monitoring tool for detecting changes in mountain vegetation. Beyond data collection, MIREN has advanced theoretical frameworks, including refining the biotic resistance hypothesis in mountain ecosystems. The network has also strengthened the connection between science and policy by engaging with land managers and conservation practitioners to develop effective mitigation strategies. As MIREN marks its 20th anniversary, this talk will highlight key scientific findings, methodological advancements, and future challenges. With increasing pressures from climate change and human activity, understanding and managing mountain invasions remain critical. Looking ahead, we aim to engage new scientists and stakeholders to expand MIREN’s core initiatives, introduce new ideas, and address emerging challenges in biological invasions and species redistributions in mountain ecosystems.
