Researchers working in one of the world’s most biodiverse and threatened ecosystems have discovered a new plant species, Castela senticosa, which they recommend be designated as endangered. The plant, which grows as a small bush sheathed in an imposing layer of thorns, was found during a survey to catalog the flora of the Martín García mountain range in the Dominican Republic.
“We were collecting everything we came across with the goal of having a complete species list for the entire mountain range,” said lead author Lucas Majure, an assistant curator at the Florida Museum of Natural History and curator of the University of Florida Herbarium
Hispaniola’s mountains support large swaths of intact tropical dry forests, highly diverse ecosystems that — like the rainforests they border — are globally imperiled due to the combined effects of deforestation, overharvesting and climate change. But although they face the same threats, the destruction of a tropical dry forest might mean the loss of considerably more species. That’s because rainforests are often found in lowland basins, where conditions like rainfall, temperature and soil type are similar over large areas. While species diversity is high, many rainforest plants can have distributions that span hundreds of miles.
