Nutria are a common site along the lower Columbia River and its tributaries. Large, semi-aquatic rodents, they burrow into the sides of river banks and munch on river vegetation, creating erosion and impacting shoreline vegetation. Like many invasive species, Nutria have detrimental impacts to the local ecosystem and are the focus of management efforts to control their population. On March 28, PSU, USGS, and the US Fish and Wildlife Service will convene a Nutria Management Meeting in Vancouver to talk about nutria management tools and coordination. Click here to learn more.

The in-development Lewis River-Vancouver Lake Water Trail being developed by the Vancouver-Clark Parks and Recreation gets kudos from this Columbian Editorial for their "forward thinking." It notes that an offical water trail and a well-designed web site would "coodinate kayaking and canoieing activites" and promote paddling safety. Along the way it praises two existing trails - the Cascadia Marine Trail in Puget Sound, and our own Lower Columbia River Water Trail! Read the editorial here.
After a few hours of lively discussion at the Water Trail Signage workshop this August one thing was clear - people signage on the Lower Columbia River Water Trail will enhance both the trail's identity, but more importantly the use experience as well. The workshop's 25 participants discussed the purposes and goals of signage while critiquing three signage concepts. After much debate, general consensus emerged that an adaptatoin of the Water Trail logo, with River Miles, a paddling icon, and other details was the way to go. Next steps are in process with the first signs scheduled to be installed within the next few months.
