- The Pampa is a fertile plain that covers much of the central and eastern part of the country, extending from the Atlantic coast to the Andes Mountains.
- The Pampa is characterized by its tall native grasses, known as "bunchgrass" or "pasto alto," which can grow up to 1.5 meters (5 feet) tall.
- Other common plant species include shrubs, herbs, and wildflowers, such as verbenas, carnations, and thistles.
- Trees are relatively rare in the natural Pampa, although some species such as the ombú (Phytolacca dioica) and the tala (Celtis ehrenbergiana) can be found in scattered groves or along riverbanks.
- This natural vegetation has been significantly altered by human activity, especially due to the expansion of agriculture and urbanization in the region around Buenos Aires.
