This paper describes a nature-based social-emotional approach to supporting young children's holistic development that can be applied in a range of early childhood settings from forest kindergartens and nature-based preschools to more traditional center-based early childhood programs. "The Social-Emotional and Environmental Education Development (SEED) Framework" blends early childhood education, environmental education, and social-emotional development through the integration of best practice recommendations from (a) "National Association for the Education of Young Children Early Childhood Program Standards," (b) "Early Childhood Environmental Education Programs: Guidelines for Excellence," and (c) "Pyramid Model for Supporting Social-Emotional Competence in Infants and Young Children." The "SEED Framework" provides early childhood programs a guide for integrating and infusing a nature-based social-emotional approach throughout all aspects of their program.
