Zapus hudsonius preblei Interim Survey Guidelines, May 27, 1997 7
course, urban/rural housing unit, mining activities, etc.) to the site of the traps.
In addition, for each site where a population of Preble's is found, the following information
must be collected and included in the survey report:
7. Map the population location on a USGS 71k minute quadrangle map (and on a finer
scaled map or engineering drawing if available). Locations will be recorded at least
to a precision of 'k 'k of a section, township, range (e. g., 40-acre tract).
8. Number of individuals captured or seen.
9. Note the specific geomorphologic, hydrologic, and soil conditions where
individuals are found if they vary from the site description above.
10. Note the physical condition of the individual, approximate age, sex, size (total,
hind feet, body, tail), weight, and any other important or distinguishing features
that might be significant (e.g., enlarged mammary glands due to lactation, scars,
missing limb or toe, etc.). Include a photograph of individuals captured and of
capture sites;
11. Note any other possibly-relevant ecological/ethological information.
9. SURVEY METHODOLOGY, PROTOCOL, AND EQUIPMENT
The surveyor should exercise care and be acquainted with and follow the Center for Disease
Control's Hantavirus instructions and recommendations when dealing with rodents.
The purpose of most Preble's surveys will be to determine presence or absence of the
subspecies. However, these guidelines also contain important information for more
comprehensive (e.g., distributional, ethological, density, feeding, etc.) Preble's studies. The
surveyor is responsible for obtaining the necessary trapping/collecting permit from the CDOW
or WGFD, and (if/when Federal listing occurs) the Service. If the subspecies is found at
previously undocumented sites, CDOW or WGFD, and the Service should be immediately
contacted. Further studies of Preble's at the site should be conducted only after coordination
with CDOW or WGFD, and the Service.
Only small-mammal live traps (folding and non-folding) will be used in the surveying efforts.
The recommended live-traps are the Sherman and the Longworth. Use of any other types of
live-traps or capturing devices to survey for Preble's will need clearance from the Service
prior to trapping. As traps are set, they will be checked for sensitivity. Only traps in
excellent condition will be used. Traps must be free of bait and debris that might interfere
with action of the treadle or door. New traps will not be used until they have been 'seasoned"
(i.e., exposed to the natural elements, used) nor will traps be used that are contaminated with
