Safety Information
Toxicity Details
The tree itself is non-toxic. The seeds are edible (raw or cooked) and traded locally as food, similar to other Sterculia species. The main hazard is mechanical irritation from fruit capsule hairs, not chemical toxicity. No systemic poisoning from any part of the tree.
Skin Contact Risks
MODERATE risk from fruit handling. The inside of fruit capsules contains stiff, orange, needle-like bristles (urticating hairs) that penetrate skin and cause local irritation and pain. ALWAYS wear gloves when harvesting seeds or handling fruit capsules. The tree bark, leaves, and flowers are safe to touch.
Allergenic Properties
LOW allergen risk. Possible minor allergic reactions or localized irritation from fruit contact, but no major toxic effects. Standard wood dust precautions apply.
Panamá
The Panamá tree (Sterculia apetala) is one of the most impressive giants of Central American tropical dry forests. With massive buttressed trunks and spreading crowns reaching 45 meters, these magnificent trees are landmarks in Guanacaste's landscape and critical habitat for scarlet macaws.

Wildlife Value
Exceptional habitat:
Panamá trees are among the most important nesting sites for scarlet macaws in Costa Rica. The large hollow branches and trunk cavities provide safe nest sites, making conservation of these trees critical for macaw survival.

Physical Properties
Despite its impressive size, Panamá wood is rarely used commercially due to its softness and poor durability. Its value lies in ecosystem services rather than timber production.

Conservation Status: Stable but Declining
Population status:
While not globally threatened, large mature Panamá trees are becoming rare due to agricultural expansion. Their importance for scarlet macaw nesting makes preservation of remaining giants critical.

Sterculia apetala stands as one of the most impressive trees of Costa Rica's dry forests — a living monument that may have witnessed centuries of history. These giants are irreplaceable habitat for scarlet macaws and countless other species. Every mature Panamá tree represents not just a tree, but a functioning ecosystem providing food, shelter, and nesting sites for the remarkable wildlife of Guanacaste.
