BiodiverseCity St. Louis logoBiodiverseCity St. Louis is a growing network of organizations and individuals throughout the greater St. Louis region who share a stake in improving quality of life for all through actions that welcome nature into our urban, suburban and rural communities.

BiodiverseCity St. Louis recognizes our region's reliance on biodiversity, the variety of life, and natural systems. We depend on biodiversity, not only for the air we breathe, the water we drink, and the food we eat, but also for the basic health, livability and economic prosperity of our region.

Species Spotlight

Golden Alexander (Zizia aurea)

Zizia aurea, commonly known as golden Alexander, is a perennial wildflower that plays a vital role in the ecosystems of Missouri and the broader Midwest region. This species thrives in moist, rich soils, often found in woodland edges, along riverbanks, and in prairies, and is typically found in small colonies clustered together.

The plant’s bright yellow flowers emerge in early spring, perfectly timed to the arrival of many pollinators returning from migration or coming out of winter hibernation. As one of the first wildflowers to bloom in the spring, the flowers provide an essential food source for a variety of bees and butterflies, particularly the Missouri woodland swallowtail butterfly.

A personal favorite of mine, its small yellow flower clusters remind me of fireworks or a sparkler. Each tiny flower has five sepals, five petals, and five stamens. The flat-top cluster, called compound umbels, top the stems which grow to 3 feet tall. Golden Alexander is a member of the carrot family, Apiaceae, and can be distinguished from other relatives by the absence of a flower stalk on the central flower of each umbel.

Historically, indigenous peoples and early colonists used part of this plant for medicinal purposes, such as treating fever and healing wounds. Parts of the plant are edible, particularly the young leaves, flowers, and roots. The leaves can be eaten raw like salad greens or cooked like a cruciferous vegetable, and the roots can be used to make tea.

Golden Alexander blooms April through August, so keep an eye out for these bright yellow flowers this spring and summer!

City Nature Challenge 2025

Special thanks to everyone who contributed to the City Nature Challenge this Spring! In the St. Louis region, over 10,000 observations were made from Friday, April 25 through Monday, April 28, and over 1,700 species were identified. Check out the project’s findings.  

Thanks to everyone who attended either the bioblitz in Forest Park or the species identification happy hour at Urban Chestnut this year—be sure to join us next year if you missed it!

Save the date: 2026’s City Nature Challenge is April 24–27!

Great Read

Book coverBeaverland: How One Weird Rodent Made America by Lila Philip

Often seen as a nuisance, the North American beaver is, in fact, crucial to our environment. In Beaverland, author Lila Philip follows the beaver throughout history from multiple perspectives.

Throughout this book, Philip weaves together ecology, history, and personal stories into a cohesive narrative. She meets fur trappers, scientists, environmental stewards, and passionate beaver advocates, learning from each about their perceptions of the beaver’s role in our environment.

She compares the role of indigenous peoples, who hunted beavers for meat and fur but avoided overhunting and often viewed beavers as sacred animals, alongside Europeans, who prioritized the profit of beaver pelts in the New World. This historical shift in perception of beavers coincides with what American geologists call “the great drying,” a period between 1600 and 1900 when the country’s rivers and wetlands dramatically shrank. And yet, the beaver persisted—returning from near extinction to a stable population today, thanks to conservation efforts.

The reader also learns about the ecological importance of beaver dams as a potential remedy for effects of climate change. Dams create ponds, which foster ecosystems and help manage water flow, offering possible relief from both droughts and floods.

I found this story uplifting, especially as Philip draws parallels between humans and beavers. She suggests we share common traits: when beavers want to build, they build; when they want to reshape the landscape, they do. As she writes, “beavers are the only animals apart from man that radically transform their environment.” Philip reveals how this often-misunderstood creature has significantly shaped the American landscape, economy, and culture.

Beaverland is a great read for nature lovers, biodiversity enthusiasts, historians, and anyone curious about how a rodent helped build our continent
