ABSTRACT
Interpretation has a special relationship with national parks. As every practising or would-be interpreter knows, the concept of interpretation was first explicitly presented in Freeman Tilden's Interpreting Our Heritage, based on approaches and techniques developed by the US National Parks Service (Tilden 1957). Tilden's central thesis — ‘through interpretation, understanding; through understanding, appreciation; through appreciation, protection’ — offered a resounding rationale for interpretation in the service of conservation.
