This page presents results to date from our program. You can view wildlife reports made by motorists over the past month and year anytime by visiting our I-90 Wildlife Observations page.
Year 1 Report (November 2010-2011)
During Year 1 of I-90 Wildlife Watch (November 2010-November 2011), website visitors reported 529 individual animals (465 live, 64 dead). After we removed 4 live and 9 dead duplicate records from the dataset, the total number of individual animals reported was 516 (461 live; 55 dead).
These reports represented 14 mammal species—including deer, elk, black bear, cougar, bobcat, coyote, otter, and others—as well as several bird species. The majority of the animals reported were deer and elk. Of the 516 individual animals reported, 410 were deer and elk.
Year 2 Report (November 2011 – November 2012)
In our second year, the website received fewer visits than the first year when the program was launched but still attracted thousands of visitors. This year 70% (1,497) were new visitors and 30% (643) were returning visitors for a total of 2,140 visitors. Visitors came from 14 countries and 46 states during Year 2. Like Year 1, the majority of visitors (79%) came from Washington. Visitors reported 282 valid (i.e. presumed authentic) wildlife sightings made in the survey area during Year 2, comprising a total of 241 live and 41 dead animals. Again, as in Year 1, among mammals, dead ungulates (deer and elk) and carnivores were reported in similar numbers while ungulates represented the majority (83%) of live mammal sightings. While the results of Year 2 generally supported data from Year 1, there was one exception. In Year 2, the number of live and dead animals in the I-90 Snoqualmie Pass East (I-90 SPE) project area from Hyak to Easton was significantly higher than in the control area (North Bend to Hyak), even after removing live bird sitings. In the I-90 SPE project area, 171 reports of animals, including 133 live mammals, 18 live birds and 20 dead animals were reported. On the contrary, a total of only 111 animals, including 84 mammals, 6 live birds and 20 dead animals were reported in the control area.
