Some ecosystem services provide//na/ value to end-users (e.g., trees give wood production), while others are /nfermed/ate since they provide a basis for a final "valued" product (e.g., soil supports forestry). That is, there is no existing economic production or household consumption where these services are inputs. Examples are by their nature rather abstract, but include those services that are valued for reasons of what is usually termed "non-use" or "passive- use".
