| 説明 | In the Idaho National Labortory, fire increases the abundance of Poa secunda while reducing the abundance of Bromus tectorum, even over the long term. This site had burned earlier in the 1990's, in the foreground, hence the abundance of Sandberg's bluegrass and yellow rabbitbrush and the lack of Wyoming big sagebrush. This site lies in the Wyoming big sagebrush steppe of the Idaho National Laboratory, north of Middle Butte and just north of highway 20, Bingham County, Idaho. This photograph was taken a few days just before the 15 July 2010 Jefferson fire (the sagebrush steppe of the Idaho National Laboratory was still green and lush given that the 2010 was a relatively wet and cool year). |
