SAN DIEGO — In the 1980’s there have been hundreds of thousands of Monarch Butterflies overwintering on the coast of California, now these numbers have declined dramatically. Sarina Jepsen is the direct of endangered species on 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 collectively by the hundreds to generate warmth and journey 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, these quantity have slowly gone down.

“Then three years ago the numbers dropped to 30,000 monarchs and held steady for two years. We had 30,000 Monarchs on the California coast.”

Since the hundreds of thousands of Monarch Butterflies have been counted, their quantity have declined dramatically and whereas we largely see these stunning little guys within the spring and summer season as soon as the cool climate of fall arrives, they migrate to their overwintering habitat alongside the coast – locations like Monterey Bay and Pacific Grove, California, the place this year the numbers are so low specialists are involved, they may disappear utterly.

“Researchers have predicted that once the Monarch population goes below 30,000 butterflies in the west it would spiral to extinction.”

 The worry is that is likely to be occurring.

“Last year we had 30,000, this year we had 2,000 so my concern is that the prediction is coming true.”

 Jepsen says there are a number of causes inflicting the decline.

“First and foremost is habitat loss and habitat loss, both their over wintering habitat which continues to be cut down each year as well as the areas where they breed.”

In the central valley of California agriculture pesticides are contaminating milkweed.

“Also, climate change is playing a role.”

The depend bottomed out in Pacific Grove California

“This year at the Butterfly Sanctuary in Pacific Grove we had zero, in a town that calls itself Butterfly Town USA.”

 As dire because it sounds people might help.

“So, we recommend planting milkweed, native milkweed and native flowers to support the monarch population early in the season.”

 Sarina believes the monarch butterfly is price it!

 “My hope also is that enough people get involved and that we can actually make a difference.”
