Once ubiquitous in North America, the monarch’s striking orange and black wings are likely the first image that comes to mind when picturing a butterfly. The monarch is famed not only for its beauty, but also for its role in a healthy ecosystem – the pollinators are a critical support to some uniquely American landmarks: from the Great Smoky Mountains to Zion National Park. Yet, over the past few decades, the monarch has experienced a dramatic dip in population.
As the eastern members of this iconic species prepare for their annual migration to Mexico, on this episode of the AASHTO ETAP Podcast we talk with Arizona Department of Transportation’s Roadside Resource Specialist, Kris Gade, Ph.D — one of the professionals leading the charge for monarch conservation.
