The Black River is one of the longest rivers in

Rio Minho was 92.8 km long.[3] Its name refers to the darkness of the river bed caused by thick layers of decomposing vegetation. Over 100 species of birds have been recorded in the Black River morass.[3]

Sources

The river's source is the

Route

Immediately after its emergence, the river meanders gently through the cane fields of the Appleton Estate. It receives a boost from the

Trelawny-Manchester border. Approaching Maggotty, its speed increases and occasional rapids occur.[4]

Passing through Maggotty, the river runs alongside the road and goes down several small waterfalls and the Black River Gorge, located in the

African perch,[5] so called because of its reputation as a prolific breeder. The Jacana
is also known locally as the ‘Jesus bird,’ as it gives the impression of walking on water when it wades among the floating leaves of aquatic plants.

Middle Quarters are located between the Upper Morass and the Lower Morass.[4] Middle Quarters is famous for its crayfish, known locally as ‘hot pepper shrimps.’ The traps used by the fishermen are similar to those of the Niger River
in Africa; knowledge of their making was brought to the island by slaves over 300 years ago.

The Lower Morass consists of shallow estuaries, marshland and mangrove swamps, providing a rich ecological environment for a broad range of fish, birds and other creatures including lobsters, mangrove snappers, snook and mullet.[3] Here the river is joined by the YS river[4] making the Lower Morass the largest (14,085 acres) swamp environment in the Caribbean. American crocodiles (Crocodylus acutus) inhabit the swamps,[3] but the population has declined, due mainly to loss of habitat as heavy draining for agricultural or tourist destroys their nesting places. Birds found here include egrets, herons and ospreys. The mangrove trees of the Lower Morass are sometimes spectacular with aerial roots sent out like spiders' legs, sometimes dropping 40 feet into the river.

The river reaches the sea (18°01′18″N 77°50′49″W / 18.021624°N 77.846949°W / 18.021624; -77.846949) on the eastern edge of the town of the same name.[4]

Commercial use

Logwood tree trunks were floated down the Black River to the port to be shipped to England for making of dyes.[3]

Nowadays, motor boats take tourists on excursions from Black River town into the lower reaches.[3]
