' Major differences in numbers of observed animals on a day-to-day basis result from two
factors. First, big game animals are very mobile and may be found anywhere in the vicinity of
the study area. Second, depending upon the cover where an animal is located during the
survey, its observability changes dynamically. At no time does a fixed "ving census constitute
a total animal count.
Site reconnaissance conducted on October 7, 1992 resulted in the observation of approximately 30
mule deer and one red fox within the permit area. The deer were flushed from beds located below
cutbanks along Dry Creek in the center of the permit area. The fox was flushed from shrubland habitat
near the creek bottom. In addition numerous northern pocket gopher diggings were observed along
the first terrace of the stream. Over the past several years a herd of 15-20 mule deer have taken up
residence within the permit area. They are commonly observed foraging within the rail loop and often
rest near the coal loadout structure. Pronghorn are also commonly observed foraging in the center of
the permit area.
Birds. Avian species of possible occurrence in the permit area are listed in Table 11-3, Bird Species of
Possible Occurrence in the Hayden Gulch Loadout Permit Area. The list was derived from the
Colorado Bird Distribution Lat/Long Study (Chase et. al., 1982), by cross-referencing habitat
designations in the study area with those in the Permit Area. The list is augmented with additional
widespread generalist species of likely occurrence, but which aren't reflected in the lat/long study
results. The habitat codes used from the lat/long study were MS (marshes, bogs and wet hummocks),
SaRb (sagebrush/rabbitbrush), DS (greasewood/sagebrush), and Cr (croplands).
Reptiles and Amphibians. Table 11-4, Reptiles and Amphibians of Possible Occurrence in the Hayden
Gulch Loadout Permit Area, presents a list of herptiles that could potentially occur within or adjacent
to the Loadout permit area. This list was derived from the Colorado Reptile and Amphibian
Distribution Lat/long Study (Hammerson and Langlois, 1991), cross-referencing likely habitats in the
