Close.
A solar project has been built nearby but impacted the site's environment.
As an environmental impact offset (like buying CO2 credits from al Gore) , the BLM has decided it needs to get the cattle off of a nearby huge tract of land (600,000 acres) that largely incorporates the BLM land that Bundy has been using for grazing.
Hence the need to drive Bundy's cattle off the Gov't land.
The fact that Bundy has been at loggersheads with the BLM for 20 years makes their land use grab easier.
Oh, wouldn’t it be nice to see a lot of heads on pikes.
