Data and code for the paper 'Trait-based responses to forestry and reindeer husbandry modify long-term changes in forest understories' See the preprint. The R markdown document (containing R code) docs/new_figures.Rmd can be used to reproduce all figures and modelling results of the paper. The models themselves are described and fitted in the R markdown document spatial_confounds.Rmd. Among other variables, this repository contains ready-calculated community characteristics (results/clean_data/data_for_analyses/kaik.csv: species richness, Shannon diversity, species evenness, height, LDMC, SLA) and their temporal changes along with temporal Jaccard distance between 1968–1975 and 2013–2019 (results/clean_data/data_for_analyses/erot.csv) for 245 5 m x 5 m plots of field-layer vegetation. Information is also included on tree-layer SLA and canopy cover for 10 m x 10 m plots directly above them. Each plot also has information on reindeer densities in their reindeer herding district, and on the level of management intensity. For more information, see the paper. Original community amd trait data and are not included to avoid data duplication. Community data are available upon request, and will be submitted to an open repository at a later date. Original trait data are from TRY and LEDA, supplemented with our own measurements, references to trait sources are listed in docs/trait_references.txt. Climate data are from TerraClimate. ## References Abatzoglou, John T., Solomon Z. Dobrowski, Sean A. Parks, and Katherine C.
