Clark County and the Nevada Department of Wildlife spent about five years trying to get the rare frog to thrive at a pond along the Muddy River. But nearly 2,000 frogs later, the county scuttled an agreement Feb. 3 with state wildlife officials after multiple failed efforts. It’s likely now that no frogs live at the pond, county officials say.

In a way, frogs and other amphibians are a barometer of an area’s overall environmental health. Their moist skin doesn’t take kindly to environmental hazards in the air. Nor will frogs survive if water, the lifeblood of their natural environment, disappears.

The relict leopard frog’s plight isn’t unusual in the amphibian world. Amphibians throughout the U.S. and worldwide are in decline, according to a 2013 federal report.

But don’t count out this particular frog just yet. Officials aren’t giving up on the tiny 2-inch frog, believed to be extinct in the 1950s.

The county hasn’t put all of its frogs in one pond.
