Preble’s Meadow Jumping Mouse

The Preble’s Meadow Jumping Mouse is a federally listed subspecies, found in Wyoming and Colorado. Listing of the subspecies under ESA has resulted in controversy in those states, where housing and other developments are impacted. There has also been controversy over the use of genetics and other techniques in determining whether the subspecies is taxonomically valid.

RESOLVE staff led an important evaluation of the status of PMJM. The science review panel determined what constituted the ‘best available science’ on whether the subspecies was justified by the evidence. This report is also important in that it established the general principle that those evaluating status of PMJM (or other taxa) should follow the rules of taxonomy for the relevant field (mammalogy in this case). This is critical in that different taxonomic fields have different criteria for subspecies status.
