Savory National Park

Thirdly, on the video he talks about the national park in the United States. He had pointed out that the national park is misunderstood, because he thinks that national park is desertifying as badly as anything in Africa. And there had no sign of livestock in the national park. Therefore, he did some research about that national park grassland was green before, but after all, in 2002, the whole grassland has changed, it become some parts of land have a green plant, and some of soil have become degraded. He had asked the scientist for that reason, and then the American scientist had no explanation for this except that it is arid and natural. Mr. Savory said this is unknown processes. On the article, the author’s has pointed out “Mr. Savory’s
grazing method has prevented or now restores this remnant grassland patch. They have tested the effects of intensive grazing and rest from grazing on the dominant grass, black grama, in this desert grassland” (Briske 2013). After they have done that with the result, they conclude no evidence that grass cover had decreased with 13 years of rest in a noneroding landscape. Luckily, livestock producers of the region realize that flexible grazing management is needed to sustain these arid grasslands
