[PAR] [TLE] Nevada Test Site [SEP] The Nevada National Security Site (N2S2),(though the abbreviation NNSS is still used), previously the Nevada Test Site (NTS), is a United States Department of Energy reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas.  Formerly known as the Nevada Proving Grounds, the site was established on 11 January 1951 for the testing of nuclear devices, covering approximately 1,360 square miles (3,500 km) of desert and mountainous terrain.  Nuclear weapons testing at the Nevada Test Site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on 27 January 1951.  Many of the iconic images of the nuclear era come from the NTS.  NNSS is operated by National Security Technologies, LLC, a joint venture of Northrop Grumman, AECOM, CH2M Hill, and Babcock & Wilcox. [PAR] [TLE] Grindelia fraxinipratensis [SEP] Grindelia fraxinipratensis, common name Ash Meadows gumweed, is a North American species of flowering plants in the daisy family.  It is native to the southwestern United States, in Mojave Desert regions in Nye County in Nevada and Inyo County in California.  Some of the Nevada populations (including the type locality) lie inside the Nevada Test Site of the United States Atomic Energy Commission
