Field Notes: a Northwest nature blog

One of the reasons many of us live in the Pacific Northwest is the natural wonders that amaze us all. On this blog Seattle Times writers and photographers will share their explorations of the natural world from snowcaps to whitecaps. Write us at fieldnotes@seattletimes.com with your own sightings, questions and wonders to share.

Animals on the move: first survey results, and photos galore

The first results are in from the motorist survey of wildlife in the Interstate 90 corridor.

Sponsored by Western Transportation Institute and the I-90 Wilidlife Bridges Coalition and other partners, the survey is intended to better understand the animals using the corridor between North Bend and Easton. Motorists were asked to count any wildlife they see -- dead or alive -- and report it for the survey, launched in November 2010.

The results were encouraging in this respect: Motorists saw a wide variety of wildlife, from turkeys to skunks to elk. And most of the sightings were of live animals, not roadkill.

In its first 12 months, the website received 6,821 visits from all 50 states in the U.S., and 29 other countries. The vast majority of visits (83%) originated in Washington. Visitors reported 240 valid (i.e., presumed authentic) wildlife sightings made in the survey area during the first year, comprising a total of 529 live and dead animals. Sightings included both mammals and birds, with deer and elk dominating the mammals list. Of 475 mammals reported, 423 were alive and 52 were dead.

To participate in the survey yourself, check out this link. The survey will continue for at least another year.

And for those of you who can't get enough of this sort of thing, here from Conservation Northwest are fabulous photos and even some video of wildlife photographed on remote cameras all over the state -- black bears, cougars, even lynx.

The Washington State Department of Transportation is undertaking a major widening of I-90 and construction of over and under crossings for animals along the I-90 corridor by Lake Kacheelus.

The department is constructing 24 wildlife crossings in all, along a 15-mile stretch of highway between Hyak and Easton. They range from enlarged culverts to 150-foot wide widlife bridges, including one overcrossing just for animals.

The crossings will make traveling the corridor safer both for the 28,000 vehicles traveling the pass each day, and for wildlife. For more on the survey, see our story in the Seattle Times, and for more on the I-90 corridor project, see the WSDOT website.

It can be easy to forget the importance of the lands near highways to wildlife. But getting from one side of the road to the other safely is fundamental to ensuring healthy populations of everything from amphibians to large mammals that need to access lands that were important to them in their cycle of life long before our roads were placed across their travel routes.
