Looking at leks

This time of year, accessing sage grouse strutting grounds is tricky -- it could require use of snowshoes, all-terrain vehicles or snowmobiles.  In past years wildlife staff have also conducted aerial surveys of the leks.  Each Spring, Surprise Field Office wildlife staff coordinate with the California Department of Fish and Game and Nevada  Department of Wildlife to ground-check all known active leks within the Surprise Field Office boundary.  This requires visiting the leks (from a respectable distance) in the early morning hours as often as weather will permit during the sage grouse mating season.  Using a high-powered spotting scope or binoculars, wildlife staff count how many males and females they see on each visit, while also collecting basic weather and field condition data.  Due to the remote location of each lek, getting to more than one lek per sunrise is a challenge.  On this morning (March 21, 2008), Blair drove about an hour from the office in a 4x4 truck, parked on the main road and then travelled by ATV and snowshoe to the lek.
