Appendix 2 also collates and analyses the original data and comments from SOEF 2007 and 2011. It is a simple and arguably narrow measure of the rich diversity of cultural and spiritual values associated with forests, but it is important to ensure this type of benefit is included, albeit in a partial way. The categories for this indicator were restructured and given clearer definitions for the State of Europe's Forests 2011 reporting round. The categories used were: 1) cultural heritage, 2) forested landscapes, 3) trees with cultural and spiritual values, and 4) other sites with cultural and spiritual values.
