Kylie is a naturalist at O'Brien County Conservation. Growing up in Spirit Lake, Iowa, Kylie always had an interest in science. When deciding on a career in the field, she couldn’t help but think back fondly on the classroom visits and field trips led by county naturalists throughout her childhood. After graduating from Luther College with a bachelor’s degree in biology, she began working as a naturalist herself, officially becoming an Iowa county naturalist at O’Brien County in August 2025. She believes that the best way to connect with nature is to get your hands dirty. Through providing hands-on learning experiences, she hopes to instill in students of all ages a sense of appreciation for the connectedness of all living things to their environment, including humans!
