Natural History - All Ages Welcome
Join volunteer naturalists on a memorable nature hike to find and report plants and animals around Harney-Lastoka and Coal Creek Trail as part of the City Nature Challenge. The City Nature Challenge is an international effort for people to find and document plants and wildlife in cities across the globe. It’s a bio-blitz-style competition where cities are in a friendly contest to see who can report the most observations in nature, who can find the most species, and who can engage the most people. Join us at the Harney-Lastoka community gardens and bring a camera or smartphone with the iNaturalist app ready to use!

Eli M - Volunteer Naturalist
Originally from West Virginia, I spent my early days camping, biking, and hiking in beautiful natural areas all around the Allegheny and Blue Ridge Mountain Ranges, instilling a love for the natural world and developing a great interest in how ecosystems function. Throughout my life, I have been very fortunate to recreate in and learn about many different environments throughout North America, experiences that have shaped me into who I am today and who I wish to be in the future.

I have worked for many years as a scientist, teacher, presenter, and medical writer, but I love learning about the outdoors and sharing what I've learned. I have also volunteered for many years as an ESL teacher (in English, with adults from countries around the world) and love working with English language learners. .

I love to photograph and identify wildflowers. I enjoy many of the Boulder County parks, but I am most familiar with the Carolyn Holmberg Preserve at Rock Creek Farm.
