Before the arrival of the Companía Bananera de Costa Rica, a branch of the United Fruit Company, and banana plantations in the 1930s, vegetation in this area offered a great deal of biodiversity in both plant and animal resources.
Resources available to Precolumbian inhabitants in this alluvial plain consisted of riverine and ocean resources, including mangrove forests located in the Terraba and Sierpe Rivers.

The rich alluvial soils of this region facilitated historical agriculture since the 1930s.
The United Fruit Company dominated this southern region with banana plantations as early as the 1920s in Parrita and Quepos.
The UFCO entered Palmar Sur in the 1930s under the name of Companía Bananera de Costa Rica in an effort to avoid antimonopoly legislature.
 Today the landscape is still carved into agricultural fields which are owned by co-ops and consist of plantain, banana, and palm plantations.
