Las Bocas Canyon
Las Bocas Canyon is a steep gorge carved by the Frío River, located on the town boundary between the municipalities of Barranquitas and Comerío in the central region of the main island of Puerto Rico. Situated between the eponymous main subrange of Cordillera Central and the Sierra de Cayey subrange, it is notable for its untouched forests and the large population of kapok. Las Bocas, along with San Cristóbal Canyon, its larger neighbor to its immediate south, form part of the La Plata River basin.
Protection
The canyon is protected as Las Bocas Canyon Protected Natural Area and Nature Reserve, a 1,170.98-acre tract of land created through the Las Bocas Canyon Natural Reserve Committee across the [Quebradillas, Barranquitas, Puerto Rico|Barranquitas, Puerto Rico|Quebradillas] and Quebrada Grande barrios of Barranquitas and the [Río Hondo, Comerío, Puerto Rico|Comerío, Puerto Rico|Río Hondo] and Palomas barrios of Comerío. Las Bocas is currently threatened geologically by nearby uncontrolled urban and hydrological developments, particularly due to its proximity to Comerío Pueblo, and ecologically by the use of pesticides in the agriculture of nearby Barranquitas. Organizations such as Sierra Club often offer guided hiking tours into the canyon.
Flora and fauna
The canyon is famous for its ceibas or kapoks, one of which is La Ceiba Acostada, famous for its F-shape and for its age, estimated to be at least 300 years old. In addition to the famous ceibas, the plant population of the canyon includes those common in both primary and secondary forests of the Cordillera Central such as the moca, bucayo, yagrumo macho and yagrumo hembra. The area is considered a "natural aviary" due to its high diversity of birds, and it also contains one of the highest population densities of the Puerto Rican boa, particularly along the area of Piedra Blanca and the steeper cliffs of the canyon where they feed on bats and smaller reptiles. Another natural feature of the canyon is its natural bioluminescence, found in the form of bioluminescent fungi and the luminous click beetle or cucubano.
