Spanish Cedar

Cedrela odorata is native to the neotropics, distributed from Mexico through Central America to tropical South America.

• Found from Mexico (Sinaloa and Tamaulipas southward) through Central America (Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Panama) to South America (Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, and Amazonian and Atlantic forests of Brazil)
• Also found in the Caribbean (Cuba, Hispaniola, Jamaica, Trinidad, and Tobago)
• Occurs in tropical dry forests, tropical moist forests, and premontane wet forests from sea level to approximately 1,200 meters
• Often found as a scattered emergent tree in primary and secondary forests, preferring well-drained sites on ridges and slopes
• First described by the Spanish botanists Hipólito Ruiz López and José Antonio Pavón in 1799, based on specimens collected in Peru during the Royal Botanical Expedition to the Viceroyalty of Peru (1777–1788)
• The genus Cedrela comprises approximately 8 to 12 species, all native to the neotropics, all producing valuable, aromatic timber
• Spanish Cedar has been harvested commercially since the colonial era, with Spanish and Portuguese explorers immediately recognizing the value of its aromatic wood
• Extensively planted as a shade tree in coffee and cacao plantations throughout the tropics
• Widely introduced to tropical Africa, Asia, and the Pacific for timber plantations

Cedrela odorata is a large, deciduous or semi-deciduous canopy tree.

Trunk and Bark:
• Tall, straight bole reaching 30 to 40 meters (exceptionally 50 meters) in height and 60 to 120 cm in diameter
• Often with large, prominent buttresses at the base extending 1 to 3 meters up the trunk
• Bark grayish-brown to dark brown, rough, deeply fissured with thick, rectangular plates, often with a characteristic "corky" texture
• Inner bark pinkish to reddish-brown, aromatic, with a strong cedar-like scent when cut

Crown:
• Large, rounded to spreading, with heavy, ascending branches forming a wide, irregular canopy
• Trees are deciduous in areas with a pronounced dry season, losing leaves for 2 to 3 months

Leaves:
• Large, paripinnate, 30 to 70 cm long, with 10 to 22 pairs of leaflets
• Leaflets lanceolate to ovate-lanceolate, 6 to 15 cm long and 2 to 5 cm wide, dark green above, paler beneath
• Leaves emit the characteristic cedar aroma when crushed

Flowers:
• Small, greenish-white to yellowish-white, fragrant, produced in large, spreading panicles 15 to 40 cm long at the ends of branches
• Each flower approximately 5 to 8 mm long, with 5 petals
• Blooming occurs during the dry season when trees are leafless, facilitating wind pollination
• Strongly fragrant — the scent is detectable from considerable distance

Fruit:
• Woody, ellipsoidal to obovoid capsules, 3 to 6 cm long, splitting into 5 segments from the base upward
• Contain numerous small, winged seeds 2 to 3 cm long dispersed by wind
• Fruits mature during the dry season

Cedrela odorata is a canopy species of neotropical forests with important ecological roles.

• An emergent or canopy tree in tropical dry and moist forests, often growing on ridges and well-drained slopes
• Deciduous habit during the dry season reduces water loss and exposes flowers for pollination
• Flowers are insect-pollinated, primarily by small beetles, flies, and bees attracted to the strong fragrance
• Winged seeds are wind-dispersed, capable of traveling considerable distances from the parent tree
• Seeds require light for germination and establish well in canopy gaps and disturbed areas
• Young trees are moderately shade-tolerant but require canopy openings for sustained growth to maturity
• The aromatic wood and foliage contain insecticidal limonoids that deter many herbivorous insects
• Often found in association with other valuable timber species including mahogany (Swietenia macrophylla), tropical cedar (Cedrela fissilis), and various fig species
• Plays a role in watershed protection and soil stabilization on tropical slopes
• Coppices readily after cutting, making it suitable for managed regeneration systems
• The species has a complex genetic structure, with distinct populations adapted to different forest types across its vast range

Conservation Status: Vulnerable (IUCN Red List)

Spanish Cedar has been heavily exploited across its range for its valuable timber.

• Listed as Vulnerable on the IUCN Red List due to a population decline estimated at over 30% over the past three generations (approximately 150 years)
• The species has been selectively logged across much of its range for over 200 years, with the largest and most valuable individuals removed first
• Listed on CITES Appendix III (included by several range states), which requires trade documentation
• Natural regeneration is often insufficient to replace harvested trees, as the species requires specific light and soil conditions for seedling establishment
• Habitat loss from tropical deforestation for agriculture, cattle ranching, and settlement has removed significant areas of suitable habitat
• The species is affected by the shoot borer moth (Hypsipyla grandella), whose larvae damage the terminal shoots of young trees, causing branching and reducing timber quality — this pest is a major obstacle to plantation establishment
• Conservation measures include protection within national parks and reserves across the neotropics, though enforcement is often inadequate
• Sustainable forest management and enrichment planting programs in several countries aim to restore Cedrela populations in degraded forests
• Genetic conservation is critical, as different populations vary significantly in wood quality, growth rate, and resistance to Hypsipyla
