Monarchs are migrating through the St. Louis region now, but residents are seeing fewer of them than ever before. Loss of natural habitat along their migration route and increased use of herbicides and pesticides, as well as unpredictable weather caused by climate change, have accounted for an estimated 90% decline in the migrating monarch’s population since the mid-1990s. In this episode, we learn what we can do now to help support monarchs, fireflies and other ecologically important insect species in the coming year.
