CMP Direct Threats Classification v 2.0
2
The following tab contains the latest version of the Conservation Measures Partnership's (CMP) Conservation Direct Threats Classification. This classification is designed to provide a simple, hiearchical, comprehensive, consistent, expandable, exclusive and scalable classification of all direct threats to biodiversity (see below for explanation of these criteria).

History
4
This classification system is rooted in work done in the early 2000s. In 2007, the Conservation Measures Partnership in conjunction with IUCN released version 1.0 of this classification. This draft was then updated slightly in Version 1.1 which was published in Conservation Biology 22: 897-911.
5
Given that this classification is now an international standard that is used to code data, we cannot change it too frequently. On the other hand, we do need to update this to take into account new information and learning. As a result, over the past several years, CMP has been undertaking a systematic update of the earlier versions. We consulted with numerous practitioners around the world and went through an extensive comment and feedback process, resulting in this latest version. Although we feel that this classification has substantial improvements over Version 1.1 and should be used where possible, Version 1.1 is still a valid classification that can be used where relevant. We have also provided a "track changes" version showing the edits from Version 2.0 to 1.1.

What's New in This Version
7
The Direct Threats classification has undergone relatively minor revision from Version 1.1. Key changes include:
8
9
New Level 2 Threats - We have added two new Level 2 threats that have been carved off of previous Level 2 types:
10
7.4 Removing / Reducing Human Maintenance
11
8.4 Pathogens & Microbes
12
13
Reworking of Climate Change Threats - We have substantially modified 11. Climate Change to reflect our changed understanding of the impacts of climate change and severe weather events on conservation.
14
Criteria for the Ideal Direct Threats Classification
15
There is no one "right" classification system. Instead, we attempted to develop a system that optimizes the following criteria:
16
Simple - Uses clear language and examples / understandable by practitioners
17
Hiearchical - Creates a logical way of grouping items that are related to one another to facilitate use of the classification and meaningful analyses at different levels
18
Comprehensive - Contains all possible items, at least at higher levels of the hierarchy
19
Consistent - Ensures that entries at a given level of the classification are of the same type
20
Expandable - Enables new items to be added to the classification if they are discovered
21
Exclusive - Allows any given item to only be placed in one cell within the hierarchy
22
Scalable - Permits the same terms to be used at all geographic scales
