There are many different projects and activities that aim to reconnect people to 'nature' in one way or another (e.g. forest schools, family bushcraft days, ecotherapy sessions, residential camps for teenagers, arts-based forest projects, etc). I'm interested in how these programs are currently evaluated and what criteria are used to determine whether or not they are 'effective'. I would be grateful for any references, websites, or personal experiences if you are willing to share them.
