Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Native to montane cloud forests, elfin woodlands, and humid highlands. It thrives in high-altitude environments with constant moisture, frequent fog, and well-drained, acidic or organic soils.Light & Water NeedsSunlight intensity and moisture levels this plant needs to grow and reproduce successfully.

Information not available in English. Help us expand this record!BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
A key structural tree of the upper canopy or understory depending on altitude. It is heavily actively involved in watershed regulation, as its branches and epiphytes intercept moisture from passing clouds and funnel it into the ground.Toxicity / UsesToxic compounds present and their documented effects on humans or other organisms.

The winged rachis and coriaceous (leathery) leaves are adapted to tolerate high solar radiation and intense winds typical of exposed mountain ridges.
Formulates tight root symbiotic associations with mycorrhizal fungi to maximize nutrient absorption from thin, nutrient-poor montane soils.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Climate change poses a severe risk as rising temperatures and shifting cloud lines can dry out the fragile montane cloud forest ecosystems it depends on.
Habitat fragmentation caused by agricultural expansion, cattle ranching, and mountain road construction.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
It functions as an ecological pioneer species, frequently colonizing landslides, disturbed volcanic soils, and forest clearings, helping to stabilize the terrain.
