Dear Charlie et al.,
Allan Savory got his research start in Africa and his results may work in grazing-adapted habitats that evolved with large herds of grazing animals. These results do not hold in non-grazing-adapted habitats like the Intermountain West of the U.S. and many other arid regions of the World that did not evolve with large herds of grazing animals. In these regions, intermediate level grazing and short bursts of intense grazing have a devastating impact on microbiotic crust communities (nitrogen cycle), native bunch grasses, and soil erosion.
In the 1980's Allan Savory was offered a chance to test his ideas at the Sevilleta Long-term Ecological Research Station in central New Mexico and he declined the offer.
Best,
Stefan

Here's an interesting TED talk--a little slow at the beginning--that finishes strong with an almost unbelievable report and result. If you're a meat fancier, livestock maybe the salvation of the planet. It's very much worth a watch.
