Bao Bolong (also "Baobolong", "Bao Bolon" or "Baobolon") Wetland Reserve is a national park in The Gambia. Established in 1996 it covers 220 square kilometres.

The Wetland Reserve is located on the north Bank of the River Gambia, approximately 100 km (52 nautical miles) from the river mouth. The name is derived from the Bao Bolon tributary that rises in Senegal and enters the River Gambia. [cite web|title=Bao Bolo Wetland Reserve|date-2005|url=http://www.prcmarine.org/index.php?option=com_content&task=view&id=62&Itemid=23|publisher=Programme Regional de Conservation|accessyear=2008|accessdate=July 31] It extends from the River Gambia north to the Senegalese border along the Baobolon tributary.

History

On 1 January 1993, an area of 35 km² was first declared as "Bao Bolong National Reserve". From 16 September 1996 on, with an extended area of 220 km² (200 km² according to other sources), it was the first reserve in the Gambia to be acknowledged as a wetland area worth of protection according to the Ramsar Convention: "Bao Bolong Wetland Reserve". Since 1975, this convention, whose draft had been iniated by the United Nations Educational, Scientific and Cultural Organization (UNESCO), protects the habitat of water birds and Charadriiformes. For other nature reserves in the country, like Tanbi Wetland Complex or Niumi National Park (NNP), a Ramsar acknowledgement is also being aimed at by the Gambian authorities. As with NNP, it is intended to extend Bao Bolong Wetland Reserve across the border and to jointly administrate the area with Senegalese authorities.

Geography

The reserve features a length of 22 kilometres and an approximate width of nine km. The western part is located in the "Central Baddibu" district while the eastern part adheres to "Upper Baddibu", both of which belonging to the North Bank Division.

Chiefly, the reserve is made up of the river Bao Bolong's estuary, one of the bigger tributaries of the river Gambia. It is located about 100 km away from the Gambia's mouth into Atlantic Ocean. The roughly 100 km long Bao Bolong river's spring is situated in Senegal. Furthermore, BBWR includes the rivers "Salokini Bolong", "Mandon Bolong", "Duntu Malang Bolong", "Tanku Bolong" and "Katchang Bolong".

The Gambia river thereby formes the southern boundayr of the protected area. Approximately two kilometres away on the opposite bank of the river, the roughly 115 km² large Kiang West National Park is located. A some two and a half kilometres wide zone of dense mangrove forest adjoines to the river. To the west lies the town of Salikenne (population about 4,000), which is also located near the Dobo Forest Park of 7.32 km². At the western border, the Jalabiro Forest Park of 0.59 km² can moreover be found.

The northern edge is bordered by the north bank road, Gambia's secondmost important highway. Along this road and the fork to Salikenne, several smaller towns like "Nja Kunda", "Minti Kunda", "Kekuta Kunda", "No Kunda", "Konti Kunda Sukoto", "Konti Kunda Nji" and "Illiassa" are situated. In the east, following a fork of nine km length from the north bank road, the town of "Katchang" of 1,700 residents can be reached. Farafenni, with a population of more than 30,000 being the division's largest city, lies roughly 18 km outside the outer limits of BBWR to the east. Summed up, there are 25 small towns [http://www.prcmarine.org/index.php?option=com_content&task=view&id=62&Itemid=23 Bao Bolong Wetland Reserve] www.prcmarine.org] which are situated at the wetland reserve's boundaries, one among them being inside the park limits proper. The inhabitants of these towns conduct fishery for personal requirements and their stock graze inside BBWR. Furthermore, they collect timber and fire wood there.

The terrain is flat, the highest elevation is cited with 12 metres above mean sea level.

Flora and fauna

Ecosystems

Bao Bolong Wetland Reserve includes a rich fauna and flora within multiple ecosystemss. Important, protected tree species are pointed out by the "Ramsar Information Sheet", [ [http://www.wetlands.org/reports/infosheet.cfm?siteref=1GM001 Ramsar Information Sheet] ] such as "Pterocarpus erinaceus", "Parinari macrophylla", the ana tree, wild mango trees ("Cordyla africana") and Néré ("Parkia biglobosa").

Mangroves

Only in the mangrove forest of Bao Bolong Wetland Reserve the mangrove trees of the Senegambia region reach a height of 20 metres. The species "Rhizophora racemosa", red mangrove ("Rhizophora mangle") and black mangrove ("Avicennia germinans") are widespread among them.

Salt marshes

In the salt marshes, e.g. the succulent "Sesuvium portulacastrum" and grasses like"Sporobolus spicatus", "Paspalum vaginatum" as well as "Diplachne fusca" can be found. In the savanna, which at times is flooded, "Phragmites karka", "Echinochloa pyramidalis" and paper reed are very common.

Savanna

In the Savanna, trees like "Daniellia oliveri", "Terminalia albida", Néré ("Bombax costatum") and others are to be found. Among the shrubs one will encounter several species of figs, "Physostigma thonningii", "Terminalia avicennoides", "Anthostema senegalense" and "Nauclea latifolia". As of grasses, "Andropogon tectorum" and Gamba grass ("Andropogon gayanus"), "Beckeropsis uniseta" and "Pennisetum subangustum" are common.

Avifauna

The Gambia is frequently visited by ornithologists as more than 540 species of birds have been described there in topic literature. Bao Bolong Wetland Reserve is one of the major targets for tourists and scientists who intend to explore The Gambia's manifold avifauna. Among the birds of BBWR, which include 268 species pf 62 families, the "Ramsar Information Sheet" exemplarily lists the following:

Typical for a wetland, BBWR is the habitat of many water birds, which also include geese.
