Zero-Inflated Poisson Mixed Models for the occurrence (absence)* and abundance of recently emerged seedlings and juveniles older than a year (saplings).

Every variable introduced in the models is listed, but only the estimates for the variables included in the final model are shown.Site 1: Valsaín, Site 2: Arcalís, Site 3: Sierra Nevada. T: mean annual temperature, P: annual mean precipitation, GSF: Global site factor; EF: modelling efficiency; ΔAIC: difference in AIC referred to saturated model.*The parameters estimated in the binary part are referred to the probability P (finding no recruit) assessment, being 1-P the probability of presence.
