Great question! Research shows nature-based interventions (NBIs) can have meaningful benefits for autistic children. A systematic review of 24 studies (717 participants) found NBIs significantly improved social communication skills (standardized mean difference -0.59) [1,2].

Specific approaches like outdoor music therapy have also shown promise in supporting play skills in community settings [1]. For more evidence-based treatment options, Children's Hospital of Philadelphia and CDC offer helpful resources [3,4].

The Autism Research Institute also has useful assessment tools and information about starting interventions [6]. Nature therapy appears to be a promising complementary approach worth exploring. Let me know if you'd like more details!
