Ramón / Breadnut

Overview

Ramón (Brosimum alicastrum), also called breadnut, is a large canopy tree of the fig family (Moraceae) that reaches 30–45 m in mature humid forests. The bark is smooth and grey-white; leaves are simple, alternate, and glossy. When cut, branches and leaves exude a milky white latex characteristic of the Moraceae. The fruit is a small, fleshy drupe about 2–3 cm in diameter, containing a single large, starchy seed — the “breadnut” — that is the tree’s most ecologically and nutritionally significant product.

Ramón is one of the most productive trees in the Neotropical canopy, with individual specimens documented yielding 150–180 kg of fruit per year for 120–150 years. The seeds are 13–17% protein, rich in tryptophan and lysine, and were an important food source for pre-Columbian Mesoamerican communities — a nutritional profile that has drawn renewed interest in food-security contexts.

Why Tortuguero

In Tortuguero’s primary and secondary forest patches, ramón is a keystone tree: its fruiting cycle creates reliable wildlife congregation points that are predictable across years. Howler monkeys (Alouatta palliata) and spider monkeys (Ateles geoffroyi) forage ramón seeds and leaves directly; mealy parrots and red-lored parrots work the fruiting crown for seeds; keel-billed toucans and many frugivores take the fleshy drupe. Seed dispersal is primarily by bats and large-bodied birds, which makes ramón both a wildlife attractor and a driver of forest regeneration.

The tree also tolerates periodic flooding — important in a landscape where canal-side soils are seasonally inundated — and its deep root system stabilizes the alluvial soils of Tortuguero’s forest patches.

How to see them (honestly)

• Identification: look for the large, buttressed trunk with smooth grey-white bark in the primary forest interior. The Tortuguero trail network passes through forest patches where ramón is among the dominant canopy trees.
• Wildlife connection: during fruiting (May–July), listen for howler groups in the canopy at first light — a large howler troop in a single tree overhead often means a fruiting ramón or fig.
• Park context: the beach-ridge forest between the Tortuguero village trail and the Caribbean beach contains ramón along with other Moraceae. The tree’s size is diagnostic — expect full canopy height, not understory.
• Latex test: if a guide cuts a small twig, the white latex confirms the family.

Status note

The IUCN lists ramón as Least Concern globally, with a stable distribution across its range. It is not threatened as a species, but like all large-statured canopy trees, individual ramón trees take decades to reach reproductive size — making forest clearing locally irreversible on human timescales. The primary-forest patches within Tortuguero National Park protect some of the larger specimens on Costa Rica’s Caribbean coast.
