The Lower Keys marsh rabbit was once abundant along the chain of islands between Miami and Key West.
But aerial photos from 1958 to 2006 show that 48 percent of its habitat has been lost due to sea level rise.
Only a few hundred of the species survive on a few of the keys, including Boca Chica, Sugarloaf and Big Pine, according to wildlife experts at the University of Florida.
“We kind of look at sea level rise as this problem that’s just starting. ... But what we’re showing here is that it’s already a problem,” says Robert McCleery, assistant professor of wildlife ecology and conservation.
The small Lower Keys marsh rabbit, or Sylvilagus palustris hefneri, was named for Playboy publishing magnate Hugh Hefner.
It has dark brown fur and a grayish-white belly.
