Macroinvertebrate Monitoring 2015

Aug 23, 2015 @ 9:00 am - 3:00 pm

Westmoreland Park, Portland, OR – August 23, 2015 – 9:00 AM – 3:00 PM

(Note: Participants must also attend the training session held the previous Thursday at the Johnson Creek Watershed Council office, Portland, OR – August 20, 2015 – 6:00 PM – 9:00 PM)

Why Conduct Macroinvertebrate Monitoring?

Stream restoration work is done to improve habitat for life in the stream. By looking at the macroinvertebrate (animals without a backbone that are visible to the unaided eye; insects, crustaceans, mussels, worms) communities following restoration, we can measure the response of stream life to habitat changes and the effectiveness of restoration. The City of Portland and the US Army Corps of Engineers reconstructed the Crystal Springs Creek channel in Westmoreland Park in 2013, restored the duck pond and stream at these locations to create a more natural stream channel and planted native vegetation to help cool the stream. The restoration project can benefit macroinvertebrates and fish, and surveys will be part of long-term monitoring activities to measure the health of the stream and monitor the effectiveness of restoration activities.  This is our second season of post-restoration survey work.

Who Can Help?

No prior experience is required. Volunteers must register for both the classroom training session and the in-stream survey work. Prepare for an evening in the classroom and then a day in the water and wear clothes you don’t mind getting wet and mucky. Closed-toed shoes are suggested because of the possibility of sharp debris in the stream.

Please dress for the weather and bring plenty of water!

What Will the Work Involve?

Volunteers will learn about the biology and ecology of stream macroinvertebrates, learn how to identify some of the most common families of macroinvertebrates, and learn stream survey methods during an evening classroom training session. On the following Sunday, Volunteers will then spend the day in and near the stream to collect macroinvertebrate samples, record habitat data, and use their identification skills to help identify collected samples on-site.
