1978: Taken 20 years later from the same spot, this 1978 photo shows that the same species are dominant. All the species had increased their cover inside the plot. A new species, whitestem paperflower (Psilostrophe cooperi) had appeared in the plot. Good growing conditions in 1978, including good rains, fueled the increase in ground cover by both annuals and seedlings of perennial plants. (Photo credit: Raymond M. Turner/U.S. Geological Survey)
