Since 1988 the local government has been using airplanes to sow grass seed in the eastern section of the desert area.The grass,a hybrid designed to survive in harsh conditions,now dots the desert.Even large pastures have formed,with a total of 1,000-sq-km of grassland in the area,producing 460,000 tons of fodder for livestock every year.The locality's efforts are one part of China's plan to devlelop a"green Great Wall"in north China,consisting of a forest belt extending thousands of miles from east to west.
