Practitioner beliefs about and understanding of natural environment interventions were examined. Sixteen early intervention practitioners from two programs in a southeastern state were interviewed about their understanding and use of natural environments as sources of learning opportunities for young children. Practitioners in one program had considerable experience with natural environment interventions, whereas those in the other program had little or no experience with natural environment interventions. Results indicated considerable variability and understanding between experienced and novice practitioners about the sources and characteristics of natural environment practices. Implications for promoting practitioners? understanding and adoption of natural learning environment practices are described.
