The plains of the province have a high human presence. Cultural vegetation dominates almost all the landscape of the zone: towards the northwest, the center, south, and sub-littoral areas one can find agricultural crops, sugar cane, pasture lands, and secondary vegetation.
Natural vegetation is represented by perennifoliate woods, typical of marshlands, located to the north of the Laguna de la Leche.
Wild flora is typical and associated to marshland and mangrove-tree-community vegetation. Towards the north one can find the jata guatacuda palm (Copernicia rigida) of up to 6 m (20 ft) of height. The flora of mangrove-tree communities is very well preserved and rich in wood, industrial, and melliferous resources.
