#' Mortality of lianas (vines) in tropical forests
#'
#' @description
#' This study is part of the project "Diversity and dynamics of vascular
#'  epiphytes in Colombian Andes"
#' supported by `COLCIENCIAS` (contract 2115-2013). The data corresponds to
#'  the first large-scale
#' assessment of vascular epiphyte mortality in the neotropics. Based on two
#' consecutive annual surveys,
#' we followed the fate of 4247 epiphytes to estimate the epiphyte mortality
#' rate on 116 host trees
#' at nine sites. Additional variables were taken from the area of study in
#' order to find relationships
#' with epiphyte mortality.
#' @usage
#' data(deadlianas)
#' @format The data frame contains four variables as follows:
