spring has sprung
Spring comes about 10 days earlier in the United States than it did two decades ago, a consequence of climate change that favors invasive species over indigenous ones, scientists said on Tuesday.
The phenomenon known as “spring creep” has put various species of U.S. wildlife out of balance with their traditional habitats, from the rabbit-like American pika in the West to the roses and lilies in New England, the environmental experts said in a telephone news briefing.
“The losers tend to be our native plant species,” said Charles Davis of Harvard University, who studied plant changes in Concord, Massachusetts, where American conservationist and philosopher Henry David Thoreau lived a century and a half ago.

springtime starts, and then it stops, in the name of something new.
