The MIREN rock survey

On this page, you will find the necessary documents if you want to join the MIREN rock survey and want to upload your data to our growing database


The overall goal of the Mountain Invasion Research Network (MIREN) rock survey protocol is to study rock cliff vegetation around the world. We aim to (1) investigate the impact of rock climbing on these communities, (2) investigate the impact of rock climbing on the spread of alien plant species, (3) study the importance of rocks in species ranges edges, (4) compare the species composition of rock cliff vegetation with their surroundings and (5) assess the importance of the rock microclimates as microrefugia and on the distribution of rock vegetation.


Data generated using the standardized protocol can be used to evaluate and quantify the processes and mechanisms shaping rock cliff communities at regional to global scales. We thus encourage the implementation of the protocol across the globe.


We primarily target bolted climbing routes (sport climbing, with fixed anchors), but we are open to trad(itional) climbing routes (without fixed anchors) as well.
