The data table of eleven invasive species in Hungary and Romania: Invasive species' cover, invasive species' traits, basic characteristics, trait composition, functional diversity indices and soil parameters of recipient plant communities

We studied 11 widespread herbaceous invasive alien species of East-Central
Europe and their 16 impact metrics (resident plant communities’ ecological
characteristics, trait composition, functional diversity, and soil
parameters) by sampling invaded and similar, uninvaded sites
(space-for-time substitution method). Our aim was to (1) investigate the
detailed ecological impacts of invasive plants on native plant
communities; (2) explore the type of cover-impact relationships across
impact metrics and their consistency across species; (3) study whether the
cover-impact relationship depends on functional traits of invasive
species. We present the data table with the 11 invasive species: the
status of the sites (invaded, uninvaded), the cover of invasive species at
plot level, the invasive species traits (lifespan, height, SLA, seed mass,
clonal spread, flowering duration), community characteristics (species
richness and diversity, native vegetation cover and bare ground cover at
plot level), trait composition of native plant communities (native
vegetation height, CWM height, CWM SLA, CWM seed mass, CWM clonal spread),
functional diversity (functional richness, functional evenness, functional
divergence, functional distance, RaoQ) and soil properties (N, P, organic
C, pH).
