Low plains
The Low Plains ( German Low plains ) are one of five geographical zones in Ghana .
In addition to the low plains, these are also the highlands of Ashanti , Akwapim-Togo chain , Volta basin and high plains .
The main part of the Low Plains, also called Akan Plains, extends at an altitude between 100 and 200 meters directly adjacent to the lower coastal plain from the capital Accra to the west to the border with Ivory Coast . The low plains thus extend from the coast to the Kwisa level, the transition to the Ashanti highlands, and are traversed by the second largest river system in Ghana, the Pra, with its tributaries. In addition to the Pra system, Bia , Tamo , Densu and Ankobra also flow through the Low Plains.
The country is characterized by its wide valleys, which only occasionally close around small elevations (up to 300 meters above sea level) in the landscape and rarely around small mountains (up to a height of 600 meters). Basically, the country is a change between grass and bush landscape and open rain-green forest. The coastal plain is a sub-landscape mostly only approx. Eight kilometers wide, typical bush savannah of the Low Plains and characterized by very flat land with diverse palm trees and wide sandy beaches in lagoons. Ghana's seawater desalination plants are also located here . Mangrove forests and bamboo areas can often be found in the coastal plain.
The Low Plains encompass a narrow coastal strip from Accra to Takoradi , which is only overgrown with open grass savannah . With average rainfall between 1500 mm and 2100 mm, the southwest corner of the Low Plains is the rainiest in all of Ghana. This is also where the tropical rainforest is most lush, which occurs here in the form of the evergreen rainforest.
