Short-term effects of Hurricane María on populations size and individual survival in Lepanthes eltoroensis (Orchidaceae) at the Luquillo Experimental Forest, Puerto Rico

Abstract

Plants endemic to the Caribbean region have evolved in response to hurricanes. These natural phenomena appear to be more frequent and more intense in the Caribbean region, which requires the study and understanding of their influence on responses by these plants - particularly if rare and with limited geographic distribution within the region - as a priority for conservation. We took advantage of long-term monitoring studies at the Luquillo Experimental Forest/El Yunque National Forest in Puerto Rico to evaluate the short-term changes in population size and the distribution oflife stages of Lepanthes eltoroensis, a species listed as endangered under the Endangered Species Act of 1973, in response to Hurricane Marfa. We expected there to be reductions in overall population size, and also that plants at smaller developmental stages (seedlings and juveniles) would be more affected by hurricanes compared to larger plants (i.e., adults). To examine these predictions, we conducted a rapid assessment (six-month after the storm) of inventoried subpopulations of this species, and that also are georeferenced before the 2017-hurricane season. This information is valuable for effective management and conservation efforts for this species.
