Monarch Butterfly population declining

In the 1980's there were millions of Monarch Butterflies overwintering on the coast of California, now those numbers have declined dramatically. Sarina Jepsen is the direct of endangered species at the Xerces Society for Invertebrate Conservation.

"Within North America they primarily breed in the United States a little in Southern Canada and Southern Mexico and the Monarchs spend the winter in two places, the mountains of Mexico and the California coast."

The Monarch Butterflies will cluster together by the thousands to generate heat and ride out the Winter.

"In a place like Pacific Grove, California in 1997 there were 45,000 Monarch Butterflies at that one site and that was one of hundreds of locations where Monarchs overwinter in California."

Since then, those number have slowly gone down.
