Standard Taxonomic Effort

March 1, 2011 – Defines the standard taxonomic effort level information for the identification of aquatic invertebrates from California and adjacent states, and provides limited taxonomic, distribution and habitat information. This STE supercedes the CAMLnet 27 January 2003 List of Californian Macroinvertebrate Taxa.

List of Additions and Corrections

The SAFIT List of Freshwater Macroinvertebrate Taxa from California and Adjacent States including Standard Taxonomic Effort (STE) Levels

An MS Excel 2003 spreadsheet containing a list of aquatic and semi-aquatic invertebrates found in California and surrounding states. The STE is derived from this list. The ultimate goal of this list is to be a complete catalog of aquatic invertebrates found in the Southwest and surrounding areas with basic distribution and habitat information, as well as citations for the appropriate taxonomic references.


November 28, 2006 – Adopted at SAFIT’s 2006 Fall meeting, the Rules document governs the inclusion of names in the STE, and establishes procedures for maintaining and updating the STE.


A bibliographic database created with EndNote ver. 5. This EndNote Library File includes searchable keywords for many references. At present, the database includes all references cited in the STE and Master Source File as well as other taxonomic and ecological references applicable to western aquatic invertebrates.

In “.enl” format, the references can be downloaded into the user’s EndNote or other bibliographic software. When using Internet Explorer, use “Save As” and change the file extension from .zip to .enl.” For non-EndNote users, a PDF Version is also provided.

Tolerance Values & Functional Feeding Groups

The two documents provided below contain the California Tolerance Values (CTV) and Functional Feeding Groups (FFGs) as established by CAMLnet (Ode 2003), SAFIT’s precursor.

These values were used during the creation of the Indices of Biological Integrity (IBIs) established for several regions in California. These CTVs and FFGs must be used to correctly calculate the IBIs for these regions if they include metrics related to tolerance or functional feeding groups.

These documents should only be used to reference CTVs and FCGs, and must not be used for taxonomic purposes since their veracity has not been verified and known errors and omissions are present.
