Solana Beach Steps up for the Western Monarchs


As reported March 6 by the San Diego Union Tribune, “Western monarch numbers have been steadily dropping for decades, from 1.2 million in 1997 to 30,000 in 2019, but the most recent results from the 24th Western Monarch Thanksgiving Count are staggering — just 1,914 butterflies total, down from the millions that used to migrate from the Pacific Northwest and Central California to overwinter along the coast from Mendocino in Northern California to Ensenada in Baja California . . . . [A]fter wildfire ripped through the area around . . . Butterfly Town, USA, in the midst of traditional migration season . . . not a single monarch was found in Pacific Grove, a tourist mecca for people who came to marvel at the swarms of Western monarchs that congregate during the winter, clinging to eucalyptus and pine branches to find protection from the cold and wind.”


The City of Solana Beach has taken the Mayors' Monarch Pledge, a challenge sponsored by the National Wildlife Federation to encourage development of monarch habitat. The SeaWeeders have teamed with the City’s Climate Action Commission (CAC) to help, starting with a milkweed seed and seedling giveaway on April 24, 9:30 a.m. to noon at the Boys & Girls Club, west parking area, 533 Lomas Santa Fe Drive.


Important notes:

  • Reservations are required.

  • Seeds and plants will be available only to Solana Beach residents

  • Quantities are limited; no more than five plants and/or three 10-seed packets per family.

  • Donations are welcomed! The City has purchased some plants for the giveaway; more seedlings and seeds have been generously donated. Your donations will help us sponsor more events and plant giveaways in the future.

We also are working with the CAC and the City to identify public spaces where we can plant butterfly patches. Our first site will be along the east wall of La Colonia Community Center and parking area.


In your gardens:

  • Whenever possible, plant native milkweed* varieties, which are the host plants where Western monarchs lay their eggs and the food plants for monarch caterpillars.

  • Plant lots of native nectar flowers, too, so your butterflies have food to sip. Consider Yarrows, California lilac (Ceanothus), Salvias, and Monkeyflower (Mimulus).

  • Don’t use pesticides or herbicides. They are toxic to caterpillars; the aphids that might flock to your milkweed aren’t.
