Arnica montana functional traits in 27 sites - Monts d'Ardeche, France - 2021

<p>In 27 sites in southeastern France, we measured vegetative and reproductive functional traits of arnica of interest for harvesters, and recorded management actions (grazing; mowing) and ecological variables (including height of surrounding vegetation and tree cover). We examined their effects on plant traits with linear mixed models, and used path analysis to test if the effects of human management on traits are mediated by the height of surrounding vegetation. The data presented here, accompanied by the Material and Methods of the corresponding publication in Annals of Botany Plants contains all the necessary information to reproduce the analysis. This data is linked to the following accepted article in Annals of Botany Plants : Locqueville, J., Violle, C., McKey, D., Caillon, S. and Coq, S. (2023) A feedback loop between management, intraspecific trait variation and harvesting practices. <i>Annals of Botany Plants,</i> accepted manuscript.</p>
