| 摘要： | As the residential and recreational development in western Kittitas County increases, as well as interstate travel and commerce, the need arises to expand the interstate highway system to accommodate the increase in traffic volume. This increased traffic and expansion of transportation routes may potentially affect wildlife movements and traffic safety. To identify areas for potential wildlife corridors along Interstate-90 (I-90) and state highways (SR), we analyzed cougar movements and 95%fixed kernel home range estimates from Global Positioning System (GPS) collar locations of collared cougars on a 3,657km area of western Kittitas County, Washington from 2001-2004. A logistic regression model for both winter and summer was developed to determine relative probability of use by cougars for topographic and land cover characteristics. |
