none of this activity was noted.
* CDOW sensitive species
3.1.3.3 Lagomorphs:
Rabbits: Desert cottontails (Sylvilagus audubonii) likely inhabit the project area. No cottontail
rabbits were observed during surveys. However, droppings were observed in many areas
including the tamarisk thickets along Reed Wash and under greasewood shrubs.
Jackrabbits: White - tailed jackrabbits (Lepus townsendii) are likely the most common species;
however, black - tailed jackrabbits (Lepus californicus) could occur in the area. Jackrabbit
populations are likely very low in this portion of the Grand Valley. No jackrabbits were
observed during surveys; however, the habitat is suitable within the project area.
3.2 BmDs
3.2.1 Neo- tropical/Passerine Species: The Migratory Bird Treaty Act was established in
1918 to protect migratory birds, which include birds of prey (raptors) and perching birds
(passerines). Birds are an integral part of natural wildlife populations in northwest Colorado.
The public, governmental organizations and private industry place a high priority on the
protection, preservation and enhancement of avian wildlife populations and essential habitat is
found in the project area. Sensitive bird species [bird species of conservation concern (BCC)]
potentially affected and evaluated for this project were selected from the following sources
including the CDOW, U.S. Fish and Wildlife Service (USFWS) and BLM.
Colorado Division of Wildlife: The CDOW has listed wildlife of special concern in an effort to
preserve and maintain populations across their range in Colorado (CDOW 2010b). Some of the
species are formally listed by the Wildlife Commission under the state threatened and
