llr. D. li. PicF:clvie (personal corraunication) of Colorado State
t;nivcrsity saw a ?:ountain Lion about 1 mile west of Lyons in 1951;
presently this species can be nothing more than an irregular and rare
visitor to the general area including the Hennigh and Ziegle properties;
the Canada Lynx has not been recorded at such low altitudes, a:ad is now
possibly extinct in Colorado; the Bobcat probably occurs from :ime to
tine on the Ilennigh and Ziegle properties, because of the presence of
favorable habitat within the cruising range of the species. to the
north and west.
ORDER ARTIODACTYLA
Family Cervidae ,
Cervus carutdensis
OdoeoiZeus hemionus
OdocoiZeus virginianus
Even-toed Ungulates
Deer and Allies
American Elk
Mule Deer
White-tailed Deer
Although the Elk historically occurred throughout Boulder Count;,,
presently Elk seldom descend tl~e St.~Vrain River valley as far +is the
Hennigh-Ziegle study area; Mule Deer occur throughout Boulder County,
in favorable habitats; Mr. Hennigh (personal coum~unication) and Mr. C.
P.tkins (personal communication) reported the occasional occurrence of
Idhite-tailed Deer in the St. Vrain River valley adjacent to the study
area; :irs. Hennigh reported a decline in deer, observations after
development of the lime quarry to the west; deer tracks observed along
the St. Vrain River during our field studies could not be assigned to
s;.ecies, at present, a few deer, perhaps of both species, are likely to
use :.lie IIcnnigh and Ziegle properties from time to time.
