Buchiyaco

Buchiyaco (also referred to in various maps and documentary records as Buchuiyaco or Cayo Buchizaco) is a small island of coral origin and low elevation belonging to the Los Roques Archipelago, in the Caribbean Sea of Venezuela. Politically, it forms part of the Francisco de Miranda Insular Territory, within the Federal Dependencies of Venezuela. The island, covering approximately , stands out for being located in a remote and protected sector within Los Roques National Park, characterized by its extensive seagrass beds, dense mangrove formations, and notable aquatic biodiversity. Thanks to its strategic location facing the southern and southeastern oceanic circulation channels, the area receives a constant flow of crystal-clear water that feeds its rich coral reef ecosystem.

Geography

Buchiyaco Cayo is located in the southeastern sector of the Los Roques atoll, very close to the outer barrier reef and the channel known as Boca de Sebastopol. In the vicinity of this cay, other geographical features of ecological interest are located, such as Isla de Muerto, the islets of Los Castillos, Bubies Medio, Bubies Bajo, and the Sebastopol Lighthouse (Faro de Sebastopol).

Its topography is predominantly flat with low elevation above sea level, composed primarily of fine sand of coral origin and remnants of calcareous shells. The surrounding seabed is shallow and dominated by broad beds of seagrasses (mainly turtle grass, Thalassia testudinum) and the intricate submerged roots of red mangroves.

From an ecological perspective, Buchiyaco is of notable relevance due to its dense mangrove fringes and underwater marine biodiversity. The submerged roots of the mangroves on this cay serve as nursery areas or natural hatcheries for fry, juvenile fish, and a wide variety of invertebrates. Notable marine fauna inhabiting its waters include shoals of reef fish, species such as the mutton snapper (Lutjanus analis), as well as mollusks and crustaceans characteristic of the island region. Additionally, the vicinity of Buchiyaco harbors coral reef formations that provide shelter and food for protected marine life species throughout the archipelago.

Conservation

Being located within the boundaries of Los Roques National Park (declared a national park in 1972), Buchiyaco is subject to a special environmental protection regime. In the park's official environmental management zoning, this sector is classified as a Primitive Marine Zone (Zona Primitiva Marina). This designation entails strict regulatory restrictions on human and commercial tourism activities in order to preserve the fragility of the ecosystem.

Under these regulations, the development of hotel infrastructure or any alteration of the natural environment is strictly prohibited. Only controlled vessel transit along authorized routes, scientific research, and low-impact recreational activities are permitted.

Tourism

Buchiyaco Cayo is a completely uninhabited island, characterized by a pristine environment ideal for nature observation. Access to the island is exclusively by sea, using local boats (peñeros) or recreational vessels sailing from the main settlement on the island of Gran Roque or from authorized anchorages.

Permitted activities in its surroundings include swimming, snorkeling, and underwater photography, benefiting from the extraordinary clarity of the water and the calm of its coves. Due to environmental conservation regulations governing the primitive marine zone, visitors must be accompanied by authorized guides or remain in small groups to avoid disturbing the marine habitat.
