Conclusions
The MIREN road survey protocol started in 2007 with a specific purpose – to monitor non-native plant species invasions along mountain roads – but has since then proven to be well-suited for an increasing number of questions related to species redistributions in the fields of biogeography, ecology and conservation biology. The protocol is low-tech, straightforward and standardized, and can therefore be implemented immediately to fill global gaps in biodiversity data, especially in areas that are traditionally underrepresented in global biodiversity studies (Nuñez et al., 2019) or in regions with scarce or fluctuating government support for scientific research. In short, this on-the-ground, multi-regional, simple yet effective monitoring scheme is a perfect example of ‘Think globally, measure locally’, and has clear capacity to bring together ecologists from around the world to generate an even more complete picture of ongoing species redistributions in mountains.
