SAN FRANCISCO | Count finds sharp drop in monarch butterflies in California
SAN FRANCISCO —Jan 06, 2019—Researchers with an environmental group have labeled as “disturbingly low” the number of western monarch butterflies that migrate along the California coast.
A recent count by the Xerces Society recorded fewer than 30,000 butterflies, which it said is an 86 percent decline since 2017.
By comparison, the group in 1981 counted more than 1 million western monarchs wintering in California, the San Francisco Chronicle reported.
The Xerces Society conducts annual Thanksgiving and New Year’s counts and was not certain what caused the numbers to drop.
