Evans graduated in 1908 from Lineville High School in nearby Lineville, where she boarded with a family, and returned to Brownville. She took a teaching job at the two-teacher school at Hatchett Creek Presbyterian Church and soon decided that teaching would be her chosen profession. Evans studied education at both Jacksonville State Normal School (now Jacksonville State University) in Alabama and Valparaiso University in Indiana, from which she earned a teaching certificate at age 26. She then taught for three years at Shades Valley High School in Birmingham. In 1922, Evans took a break from teaching and entered the University of Alabama, earning a degree in chemistry in 1924. She was then hired to teach biology at Woodlawn High School in Birmingham, where she developed her hands-on, experience-based style of teaching. Evans believed that students were better able to develop understanding of birds, plants, and insects and "a sense of being" for all living things by listening and observing first-hand, even getting down on hands and knees.

Environmental losses such as these drove Dean to begin a grass-roots organizing effort. In the 1950s, she helped establish the Alabama Ornithological Society and founded the Birmingham Audubon Society's Wildlife Film Series, which brought nature programs to communities long before they were available on television. She became active in the Alabama Academy of Science and the National Association of Biology Teachers. She also organized and chaired the Alabama Conservation Council, a group dedicated to saving critical habitats endangered by strip mining and uncontrolled construction during the postwar years. Comprising some 50 members representing industrial, civic, religious, and educational institutions, the council campaigned against pollution and urged city planners to consider surroundings when shaping new development. The group gradually disbanded after several years, discouraged by repeated failures.
In 1951, in a further effort to give adults and other teachers a "hands on" understanding of Alabama's rich natural heritage, Dean began her unique annual Outdoor Nature Camp. She persuaded college professors and other experts to volunteer their time as teachers and leaders. She directed these camps for 13 years at sites ranging from DeSoto State Park in Fort Payne to the Bon Secour National Wildlife Refuge, near Gulf Shores in Baldwin County.

In 1967, Dean urged friend and fellow conservationist Mary Ivy Burks to undertake the task of forming the Alabama Conservancy (now the Alabama Environmental Council). She helped in the Conservancy's efforts to have the Sipsey area in the Bankhead National Forest declared Alabama's first statutory wilderness. The efforts were successful, and the site is now designated as the Sipsey Wilderness Area. That same year, the National Audubon Society presented Dean with an award for distinguished service in the field of conservation education. She was the first Alabamian to be so honored.

The legacy of Blanche Dean is evident throughout the state. The field guides she wrote are into their second and third printings, and her concept of outdoor education camps continues in the form of the Mountain Ecology Workshops at Mentone, sponsored by the Birmingham Audubon Society and dedicated to her memory. The Alabama Wildflower Society named its Birmingham chapter for her and created the Blanche E. Dean Scholarship Fund. In 1985, Dean was inducted into the Alabama Women's Hall of Fame at Judson College. Dean's true significance, however, lies those who have learned to share her love of Alabama's natural wonders and gained the determination to protect them.
