Humid Pampas

The Humid Pampa is an extensive region of flat, fertile grassland of loessic origin in Argentina. It has a precipitation average of 900 mm per year, compared to the Dry Pampas towards the west, which average less than 700 mm.

Similar to the Pampas in general, the region’s terrain is mostly hilly and of a temperate climate, though rich mollisols are more abundant here than to the west, where the soils are loessic origin are more common.

This area is characterized by four distinct seasons. The weather is generally temperate and humid and snowfalls are rare. The summer can be extremely hot and humid. The natural vegetation is made up of meadows of high grass with isolated forests of algarrobos, talas, and chanares, which were formerly common in the areas nearby the main rivers but have been mostly cut down during the 20th century. The weather in this area is much like that of European areas with natural dense forest of deciduous trees, which is, however, missing from the Humid Pampa because the soil is too compacted and not airy enough to favor the growth of large trees.
