A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2011 (October 1, 2010 to September 30, 2011) in the context of the 82-year period 1930-2011.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
Explains how critical information about dispersal and gene flow in sage-grouse populations can be obtained from the DNA coded in the sage-grouse feathers collected at their communal breeding grounds, which are called "leks".
