De Guinean forest-savanna, wey dem fi term Guinean forest-savanna transition, be distinctive ecological region wey dey West Africa.[1][2] Edey cover chaw countries for Africa here. E dey stretch across several countries wey dey include Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, den Cameroon. Dis region get some unique blend of forested areas den savannas, wey dey give diverse den dynamic landscape.

E be ecoregion for West Africa, bunch of interlaced forest, savanna, den grassland wey komot east to west wey dey divide de tropical moist forests wey dey near de coast from de West Sudanian savanna of de interior.

Setting

[edit | edit source]

De Guinean forest–savanna mosaic dey cover 673,600 square kilometers (260,100 sq mi), wey stretch komot western Senegal to eastern Nigeria, den some portions of Gambia, Guinea Bissau, Guinea, Sierra Leone, Côte d'Ivoire, Ghana, Togo, Benin den Cameroon.[3] De Cameroon Highlands of eastern Nigeria den Cameroon dey separate de Guinean forest–savanna mosaic from de Northern Congolian forest–savanna mosaic, wey dey de east.[4] De Dahomey Gap be region for Togo den Benin wey forest-savanna mosaic pull go de coast, den separate de Upper Guinean forests for Guinea, Sierra Leone, Liberia, Côte d'Ivoire, den Ghana from the Lower Guinean forests of Nigeria den Cameroon.[5]

Vegetation

[edit | edit source]
  • Forest: de forested areas insyd dis mosaic be primarily compose of tropical rainforests, characterize by high rainfall, high humidity, den diverse flora den fauna.[1][6] Dese forests be home to wide variety of plant species, wey dey include towering hardwood trees, lianas, epiphytes, den rich understory of shrubs den herbs.
  • Savanna: de savanna component dey consist of grasslands intersperse plus scattered trees, wich den adapt to periodic fires.[7][8][9][10] De savanna ecosystem dey support a different set of plant species, wey dey include various grasses, shrubs, den acacia trees.

Human settlement

[edit | edit source]

De ecoregion dey cover large areas of chaw West African nations wey dey include:

  • Senegal - much of de southern Casamance arm of de country wey dey include de city of Ziguinchor.
  • All of inland Guinea-Bissau
  • The Gambia - for particular, south of de River Gambia
  • Guinea - de band of lowland areas parallel to de coast den then running south-east of de central mountains, wey dey include de towns of Fria, Kindia den Kissidougou.
  • Northern Sierra Leone wey dey include de towns of Makeni den Kabala.
  • Côte d'Ivoire - a swathe across de middle east from Touba thru de country ein second-largest city Bouaké.[11]
  • A wide strip across Ghana wey dey include de country east of Lake Volta, wer de main town be Ho.
  • Togo - de southern plateau.
  • Benin - de southern areas wey dey include de city of Bohicon.
  • Nigeria - a large wey dey include de cities of Ibadan, wich dey mean wer de forest dey meet de savanna, de country ein capital Abuja, Lokoja wer de River Niger den River Benue dey meet, Enugu, den Makurdi.[12][13]
