“Why are Monarchs in So Much Trouble?” — introduces PHENOLOGY — or Nature’s ability to evolve and adapt in the new era some scientists say we have moved into: ANTHROPOCENE - or the Time of Man.  

The results from the Xerces Society’s Western Monarch Thanksgiving and New Year’s Counts on the California coasts leaves us shocked and raises causes for concern: 

  • 2017-2018 — approximately 192,668 monarchs
  • 2018-2019 — 28,429 monarchs — an 86% drop
  • 2019-2020 —  21,000 monarchs 
  • 2020-2021 — fewer than 2,000
  • 2021-2022 — 250,000
  • 2022-2023 — ?

Suzanne Clarke, a Sonoma County Master Gardener, will  offer some ways you can help these precious insects before it is too late! These valuable pollinators need help from home gardeners.
