Amazon Pasture 照片檔

In many cases, pasture in the Amazon is grown using an ancient cyclical process, in which the remaining grass is burnt close to the end of the Amazon's dry season, and the new grass sprouts with the first rains. These fires are usually fast and shallow, and do not affect larger trees and seeds that are in the ground, but are a kind of fertilisation that has been used for decades in the Amazon, often referred to as "slash-and-burn". With the first rains, the grass usually is lush and grows fast, just in time to recover the cattle which are usually weak and undernourished after a couple of months of heat and dry climate with much less pasture to feed on.
