Welcome to the Boulder County Nature Association
For more than 50 years, the Boulder County Nature Association has been dedicated to understanding, preserving, and celebrating the rich natural heritage of Boulder County. We are an all-volunteer, nonprofit organization committed to fostering a deeper connection between people and the landscapes, wildlife, and ecosystems that make this region extraordinary.
Through scientific studies using volunteers, a grants program for relevant research, educational programs, field trips, and conservation advocacy, BCNA brings together nature enthusiasts of all ages who share a passion for learning and stewardship. Whether you’re a seasoned naturalist or simply curious about the world just outside your door, we invite you to explore, discover, and help protect the natural wonders of Boulder County.
BCNA and Boulder Audubon jointly administer an email list serve, Nature-Net, to keep everyone updated about items of interest to both organizations.

BCNA’s Educational Hike Series
Fun Naturalist Scavenger Hunt for Kids Age 8+
Friday, June 19 from 8:30 am – 10:30 am
Children are born with a deep, biologically rooted attraction to the natural world — a phenomenon known as biophilia, first described by Edward O. Wilson. This innate connection means they are naturally drawn to living things, sensory experiences, and the rhythms of nature. From infancy, they explore through touch, smell, sound, and sight, engaging in active play like digging in dirt, chasing bugs, or splashing in puddles.
Do you have a child/grandchild 8+ who loves nature? Or needs an introduction to nature? Kids have an innate interest in nature that we can nurture for their future and for nature’s future.

Climate Change and Forests of Boulder County
Wednesday, June 10 – 8:00am – 5:00pm
Are you curious about how climate change has influenced wildfire activity and forest insect outbreaks in Boulder County? Have you ever wondered how scientists use tree rings to reconstruct fire history—and how fire activity under modern fire suppression compares to fire activity prior to fire suppression? Or how climate change is affecting tree regeneration after recent fires and driving increased mortality among mature trees?
Join Tom Veblen, CU Distinguished Professor Emeritus, and Karl Ford, BCNA Education Committee member, for the third hike in this series to explore these themes in Boulder County’s lower montane, upper montane, and subalpine forests.
KGNU Monthly Nature Almanac
Giving a Hoot about Great Horned Owls
For the May Nature Almanac, Naturalists Steve Jones and Ruth Carol Cushman head to a Louisville Park on a cool, misty evening, seeking a family of Great Horned Owls, beloved by the neighborhood, whose three baby owls have recently fledged. Owls are so good at hiding among large willow and cottonwood trees, the odds are that neither mom nor dad, nor the babies, will be seen. But Steve and Ruth Carol remain undaunted, and they give a hoot about explaining owl lore and the differences between male and female Great Horned Owls. Will any real owls speak up? Which will they find? What about a small hawk, and an angry crow, also on the lookout for Great Horned owls?
