Go Beavers!

Beaver recently moved into the Errol Creek Confluence site. Errol Creek is a tributary of Johnson Creek in Southeast Portland. Between 2007 and 2009, Environmental Services removed fish passage barriers to improve salmon habitat, day-lighting a section of the stream that used to be under SE 44th Avenue and providing more natural flood storage.  Recently beaver have been at work there, building dams that enhance the project area.  They have created a nearly half acre wetland and wonderful habitat for both juvenile salmon and amphibians.

It's an example of nature at work: beaver are some of the planet's finest engineers! Find out more about beaver and other local native wildlife here and at the Audubon Society of Portland

Weed Control Classes available for Homeowners

0 Comments | Add a Comment

The 4-County Cooperative Weed Management Area and its member organizations will be offering free classes on the identification, prevention and control of ten invasive plant species that property owners in the region might encounter.  The classes will emphasize integrated pest management principles in addressing these species. Five classes at different locations will be offered. 

The Bureau of Environmental Services has long recognized the connection between the sustainable management of stormwater and the types of vegetation growing in both our natural and urban areas.  As a member of the 4-County Cooperative Weed Management Area, BES and its partners attempt to protect and restore ecosystem services through the control and eradication of invasive species. To learn more about the City of Portland's invasive plant policies, visit the program webpage

Fish Surveys at Tryon Creek Confluence

0 Comments | Add a Comment

Environmental Services has partnered with the US Fish & Wildlife Service to collect information on fish species community and abundance within Tryon Creek between the Willamette River confluence and the Highway 43 culvert. During a recent survey last September, 45 fish were captured using a seine net at the large pool below the culvert, including cutthroat and steelhead trout, Chinook and coho salmon, sculpin, and whitefish.


The Tryon Creek Confluence Habitat Enhancement Project was completed in 2010 to improve fish and wildlife habitat conditions at the confluence of the Willamette River, and involved partnerships with Metro and the City of Lake Oswego. The work enhanced about 900 feet of Tryon Creek, and builds on prior fish and wildlife habitat restoration work performed by Oregon Department of Transportation (ODOT). In 2008, ODOT completed stream enhancements and modified the Highway 43 culvert to improve fish passage into the 645-acre Tryon Creek State Natural Area, an area well suited for coho salmon and steelhead production. 

This intensive fish survey work will be conducted on a monthly basis every other year through 2017, with an annual survey conducted in the in between years. In addition, temporal use surveys of Tryon Creek by juvenile salmon and steelhead will be conducted weekly for three months in the spring/summer during the years when the intensive monitoring efforts are being conducted. The data gathered will help determine the effectiveness of the restoration efforts at the confluence and upstream to the natural area. 



Fish Toxicity Reports and the Columbia Slough Fish Advisory

0 Comments | Add a Comment

A story published in the Oregonian in October about fish toxicity in the Columbia River and Columbia Slough helps raise awareness of the ongoing problem of contamination in fish. You should know that the pollutants detected in the fish tested were well below safety levels established by the FDA for fish purchased in retail food stores.


What can you do to reduce your risk from eating fish? PCBs, mercury and other pollutants concentrate in the fatty parts of fish. The Oregon Health Authority has long advised anglers to avoid eating the guts, fat and skin of ALL fish.


The City of Portland has conducted an active fish advisory program to immigrant and non-English speaking anglers for more than 15 years, and the city and the Oregon Department of Environmental Quality also work together to identify and control pollutant sources and to clean up contamination.
