A key foundation of any science is a common nomenclature that practitioners can use to describe—in a mutually intelligible way—the problems they are facing and the solutions they are using. For example, if a conservation project team faces the threat of “cattle” and another “grazing” and yet another “beef production,” they may not realize that they are all dealing with the same issue. As a result, cross-project learning is difficult, and the ability to meaningfully roll-up information across projects is greatly hampered.
The taxonomies presented here began with a collaborative effort between the World Conservation Union (IUCN) and CMP to create standard classifications of direct threats and of the conservation actions conservation actors can take to counter them. CMP updated the classifications in June 2016 to incorporate lessons learned and experiences from conservation teams applying Version 1 across hundreds of projects around the globe.
For those who continue using the IUCN classification system (Version 1), Version 2.0 includes the initial system, as well as a crosswalk between the two systems.
