The plot is located in the upper middle portion of the Stone Ridge Ranch Wildlife Area, along the main creek running through the middle of the property (see map), about 150 m west of the power lines. The plot is in a small (<100 square meters) stand of Trifolium variegatum with some Lolium multiflorum located on a gravel bar directly adjacent to a perennial (?) creek (flowing high right now). This association continues in small patches along the creek.; The site is lightly grazed every year.
