This dataset, 'dead_lianas_df', is a data frame containing information on the mortality of vascular epiphytes (lianas) in tropical forests of the Colombian Andes. The 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.
