The numbers were just released for the monarch wintering populations, and the data shows that the monarch population is increasing. Thanks to conservation efforts and exceptional weather conditions during the breeding season, the population is up 144% from last year. These are the highest numbers we have seen since 2007! 

Monarch populations are measured in hectares (one hectare=100 acres). This year’s total was 6.05 hectares. This is above the seasonal average (taken from 1994-2018) of 5.67 hectares!

“We are invigorated by the good news about the eastern population this year,” said Wendy Caldwell, Executive Director of the Monarch Joint Venture, “but there is much work left to be done. With the recent release of an extremely small western population, we strive to embrace an all hands on deck approach to rebuilding this population and continuing to grow and sustain the eastern population.”

One pebble can make a large ripple. Planting one or two milkweed plants in your flowerbed may not seem like a big difference, but if we all do our part we can prevent monarchs from becoming an endangered species.
