Taxonomy & Classification
Geographic Distribution
Geographic Distribution
Where to Find Amarillón in Costa Rica
Primary Habitats:
- Caribbean Lowlands — Primary rainforests
- Northern Zone — Wet lowland forests
- Osa Peninsula — Old-growth forests
- Central Pacific — Moist forests
Elevation: Sea level to ~1,200 m
Habitat & Ecology
Ecological Role
Amarillón plays crucial roles in rainforest ecosystems:
- Emergent layer — Rises above main canopy
- Keystone structure — Important nesting sites
- Carbon storage — Massive biomass accumulation
- Seed dispersal — Wind-dispersed seeds
- Microhabitat — Supports epiphytes
Wildlife Associations
Animals associated with Amarillón:
- Harpy Eagle — Nesting platform
- King Vulture — Roosting sites
- Howler monkeys — Canopy highways
- Orchid bees — Pollinators
- Numerous epiphytes — Branch communities
Amarillón is one of the most successful reforestation species in Central America. Its fast growth (for a hardwood), adaptability, and valuable timber make it ideal for sustainable forestry plantations.
Botanical Description
Amarillón is truly impressive in scale. The trunk is straight and cylindrical with dramatic buttress roots that can extend several meters from the base. The crown emerges well above the surrounding forest canopy.
Wood Properties
Appearance
The name "Amarillón" means "big yellow" in Spanish, perfectly describing its beautiful golden-yellow heartwood. This distinctive color, combined with excellent durability, makes it highly valued in construction.
Physical Properties
Uses & Applications
Amarillón's combination of strength, durability, and workability makes it one of the most versatile timbers in Central America. From structural beams to fine flooring, it performs excellently in diverse applications.
Conservation & Sustainable Use
Conservation Status
Unlike many valuable timber species, Amarillón remains relatively secure:
- IUCN Status — Least Concern
- Wide distribution — Found across large range
- Fast growth — Responds well to management
- Plantation success — Widely planted
- Sustainable forestry — Good candidate
| Factor | Status | Notes |
|---|---|---|
| IUCN Status | ✅ Least Concern | Stable populations |
| Plantation forestry | ✅ Successful | Widely cultivated |
| Natural regeneration | ✅ Good | In forest gaps |
| Growth rate | ✅ Fast | 8-12 years to harvest |
Growing Amarillón
From Seed:
- Collect fresh winged seeds
- Remove wings before planting
- No pretreatment necessary
- Plant in well-drained nursery beds
- Germination in 2-4 weeks
- Transplant when 20-30 cm tall
