The Pampas are fertile South American lowlands that cover more than one million square kilometres and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ros, and Crdoba.The vast plains are interrupted only by the low Ventana and Tandil hills, which have a height of 1,300 m and 500 m, respectively.
The soils are appropriate for agriculture due to the fact that there is more or less evenly distributed precipitation throughout the year.The area is part of the larger Paran–Paraguay Plain division.
The climate of the Pampas is generally warm in the north and cooler on the western side.During the day, summer temperatures range from 28 to 33 C, while winter temperatures are usually in the low 80's.When a warm, dry, northerly wind blows from southern Brazil, most cities in the Pampas have a high temperature of 38 C.Autumn peaks in April and May.In April, highs range from 20 to 25 C and lows from 9 to 13.The first frosts are in the south in mid-April and the north in late May or early June.
Cold waves can occur in the winter.During the day, temperatures range from 12 to 19 C, and at night from 1 to 6.With strong northerly winds, days of over 25 C can be recorded almost everywhere.In the southwest, there is more frost than around the Parana and Uruguay Rivers.The south and west have the lowest values of 10C (14F) or lower.There is never snow in the northernmost third and it is rare and light elsewhere.
It is warmer in the west than it is on the Atlantic.Within a few days, a day of 35 C can give way to nights of less than 5 C or even frost.
Precipitation can be found in the northeast, southern and western edges.In the summer, some places have an average of 120mm monthly, while in the winter it is only 20mm.The eastern areas have small peaks in the fall and the spring, with relatively rainy summers and winters.The amount of rainy days is fairly constant in winter and summer because of the weather.Among the most frequent lightning and highest convective cloud tops in the world, very intense thunderstorms are a common occurrence during the spring and summer.The most consistently active tornado region outside the central and southeastern US is caused by the severe storms.[4]
Changes to the wildlife of the Pampas have been caused by human activity.Due to the spread of agriculture and ranching, the puma, rhea, and Pampas deer have lost their habitats.[5]
The Pampas deer, gray brocket, plains viscacha, Brazilian guinea pig, southern mountain cavy and coypu are some of the native flora.The puma is the biggest predator of the region, followed by the maned wolf and the Pampas fox.
The bird species of the pampas are ruddy-headed goose, hudsonian godwit, maguari stork, white-faced ibis, southern screamer, and curve-billed reedha.It was 5, 6 and 7.
Grasses flourished, while trees were less common, because of frequent wildfires.There are many species of the Stipa grass in grassy prairie and grass steppe, which are the dominant vegetation types.The species of the Pampas is called "Pampas grass".Perennial grasses and herbs are included in vegetation.Different types of grasses occur because of water availability.
