The basic assumption that populations are at stable stage distribution may limit the ability to predict population dynamics, and the inclusion of transient dynamics may result in outputs that are more realistic. Tremblay et al. use the the R software package popdemo and data for a rare epiphytic orchid, Lepanthes rubripetala, as a model system and find that combining asymptotic and transient dynamics expands the understanding of possible population changes. For example, transfer function analysis suggests that the traditional approach of measuring perturbation on growth rates and persistence may be misleading and could result in erroneous management decisions. They conclude that an integrative approach is preferable for designing rapid and efficient interventions after disturbances, and for developing strategies to establish new populations.
