Developing and Testing a Methodology and Tools for the Inventorying of Sacred Natural Sites of Indigenous and Traditional Peoples in Mexico. This publication supported by Pronatura Mexico, the Richoberta Menchu Tum Foundation and IUCN provides an international outlook on sacred natural sites and offers an in depth methodology for assessing sacred natural sites at the national level. The objective of this research is to set the grounds and facilitate the eventual creation of a national database of Sacred Natural Sites through the development of a methodology and tools for systematically inventorying Sacred Natural Sites that is to be based on an analysis of ecosystem and habitat types. Mexico, due to its cultural and biological richness, the Sacred Natural Sites it contains, and its ample and documented experience in protected areas and other conservation strategies, as well as in the studying of indigenous and traditional cultures, is a very appropriate country to serve as the pilot ground for testing a methodology and tools leading to the eventual creation of a National Inventory of Sacred Natural Sites.
