Phoradendron longissimum

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Phoradendron longissimum faces severe threats from deforestation and habitat fragmentation in its limited range within Costa Rican cloud forests. As a parasitic mistletoe dependent on specific host trees, the species is particularly vulnerable to selective logging that removes its preferred hosts. Climate change poses an additional threat by altering the moisture-dependent cloud forest ecosystem that this species requires for survival.

Threat summary

Habitat

This parasitic mistletoe is endemic to the cloud forests of Costa Rica's mountainous regions, where it grows exclusively on specific host tree species. The species requires the high humidity and consistent moisture provided by cloud forest ecosystems at elevations between 1,500-2,500 meters.
