Question: Some Grindelia fraxinipratensis populations are located inside a United States Department of Energy reservation where what type of testing occurred?

<P0-S0> Great Lakes boreal wolf is an informal term used to describe hybrids between North American gray wolves, eastern wolves and possibly coyotes in the forests surrounding the Great Lakes. <P0-S1>  Introgression of gray wolf genes into Canadian populations of eastern wolves has occurred across eastern Manitoba, northern and eastern Ontario, and into southwestern Quebec. <P0-S2>  In the United States, gray wolves have also introgressed into the eastern wolf populations that once inhabited the western Great Lakes states of Minnesota, Wisconsin, and Michigan. <P0-S3>  Introgressions of coyotes into eastern wolf populations have also occurred in southern Ontario, Quebec, and all over the eastern Great Lakes states. <P0-S4>  While gray wolves in the northern states rarely mate with coyotes, it was long suspected that the eastern wolves which mixed with the gray wolves in the boreal forests may have also had coyote introgressions from past hybridizations with earlier coyote populations, resulting in transmittal of coyote genes into the modern day Great Lakes boreal wolves, which in turn further introduce these coyote and eastern wolf genes into other gray wolf populations. <SEP> <P1-S0> 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. <P1-S1>  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. <P1-S2>  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. <P1-S3>  Many of the iconic images of the nuclear era come from the NTS. <P1-S4>  NNSS is operated by National Security Technologies, LLC, a joint venture of Northrop Grumman, AECOM, CH2M Hill, and Babcock & Wilcox. <SEP> <P2-S0> According to the United States Census Bureau the following are the places in the United States with the lowest per capita or median household income. <P2-S1>  Locations with populations from the 2010 census are ranked by median household income as surveyed between 2008 and 2012. <P2-S2>  For comparison, locations are next listed with populations per capita income from the 2000 census. <P2-S3>  The most sizable community in 2000 (with a population of 13,138) was Kiryas Joel, New York which had a per capita income of just $4,355. <P2-S4>  In terms of geographic size, Pine Ridge Indian Reservation and the adjacent Rosebud Indian Reservation (Lakota Sioux Reservations, South Dakota) have long been among the lowest income areas in the United States. <P2-S5>  Three of the lowest ten per capita income locations in the U.S. are on these two reservations, which constitute the three largest populations in the bottom ten locations. <SEP> <P3-S0>  It is native to the southwestern United States, in Mojave Desert regions in Nye County in Nevada and Inyo County in California. <P3-S1> Grindelia fraxinipratensis, common name Ash Meadows gumweed, is a North American species of flowering plants in the daisy family. <P3-S2>  Some of the Nevada populations (including the type locality) lie inside the Nevada Test Site of the United States Atomic Energy Commission
