Layout of experimental plots that were used to compare sagebrush establishment via tubeling, wildling, and direct seeding treatments. Each 80 m x 80 m experimental plot contained four 15 m x 15 m “islands”, with islands located either 10 or 30 m apart. Within each island twenty-five Artemisia tridentata spp. vaseyana plants were planted on a 3 m-spaced grid for tubeling and wildling treatments. For the seeding treatment, the entirety of the four 15 m x 15 m islands were broadcast seeded. The 10 m vs. 30 m spacing of islands within plots is part of a different long-term study investigating the effects of island density on nucleation of sagebrush plant communities (sensu [76])
