The Maroni or Marowijne (, , Sranan Tongo: Marwina-Liba) is a river in South America that forms the border between French Guiana and Suriname. Course The Maroni runs through the Guianan moist forests ecoregion. It originates in the Tumuk Humak Mountains and forms the (disputed) border between France (region of French Guiana) and Suriname. In its upper reaches, it is also known as the Lawa, and close to its source it is known as the Litani. The total length of Litani, Lawa and Maroni is . There are two nature preserves located in the estuary region on the Surinamese side of the river, near the village of Galibi. They provide protection for the birds and the leatherback sea turtles that hatch there. Territorial dispute In 1860, the question was posed from the French side, which of the two tributary rivers was the headwater, and thus the border. A joint French-Dutch commission was appointed to review the issue. The Dutch side of the commission consisted of J.H. Baron van Heerdt tot Eversberg, J.F.A. Cateau van Rosevelt and August Kappler. Luits Vidal, Ronmy, Boudet and Dr. Rech composed the French side. In 1861 measurements were taken, which produced the following result: the Lawa had a discharge of 35,960 m3/minute at a width of 436 m; the Tapanahony had a discharge of 20,291 m3/minute at a width of 285 m. Thus, the Lawa River was the headwater of the Maroni River. There were no problems with this decision until 1885. However, the discovery of gold in the area between the Lawa and the Tapanahony created a new border conflict. On 29 November 1888, France and the Netherlands reached an agreement that the conflict should be subject to arbitration. Czar Alexander III of Russia, acting as the arbitrator, decided that the Lawa was the headwater of the Maroni, and thus should be considered the border. However, this decision created another issue as to which river is the source of the Lawa. The Netherlands considered the Malani (Marowijnekreek in Dutch) to be the source of the Lawa; the French considered the Litani, located further to the west, to be the source of the Lawa. This issue has still not been resolved. The Litani originates in the Tumuk Humak Mountains at approximately ° N 55° W; along its path it is fed by Koele Koelebreek, the Lokereek, the Mapaonikreek and the Oelemari River. The Malani also
