Stone Bridge Plantings

IMGP0291

As the days grow shorter and the weather becomes wetter, that means the start of planting season for the Watershed Council! We have been planting many native species out in the field this month, slowly clearing out our nursery to make room for when the Plant Sale orders arrive in early February.  With the help of two groups of Pacific Academy students, we planted over 60 native species at the Stone Bridge, which crosses Nettle Creek, a major tributary to Tryon Creek in the Lake Oswego area.

As many of you know, the Stone Bridge is an exciting project that was completed this past summer. The old Stone Bridge contained a culvert that blocked off access for fish populations to spawning areas. The new wooden bridge has no culvert and is a great step in completely opening Tryon Creek for spawning fish. You can read a more detailed explanation of the project here.

After the construction, the area surrounding the new bridge was in need of restoration. We had 15 students from the the Pacific Academy help us with the restoration. The Pacific Academy is a small, therapeutic alternative school operated by the Northwest Regional Educational Service District and located in Washington County. This service-learning opportunity allowed students to learn about the bridge replacement project, fish migration, riparian habitat, native plant identification, and erosion.

Students also learned techniques on how to plant natives effectively. With this new knowledge, students got to work with their shovels. The digging was a little rocky but the students persevered and were able to plant 65 species, which included salmonberry, fringe cup, willow, and ninebark, to name a few. If you get a chance, hike down to the site to see the new bridge and the array of native plants.

We would like to thank the Pacific Academy students and teachers for partnering with us for the project. We also want to thank Carl Axelsen for helping coordinate and lead the project – his efforts made the entire planting possible!

No Ivy Day

 

We had a great turnout to both of our sites for No Ivy Day on Saturday, October 25. If you are not familiar with No Ivy Day, it is an annual city-wide event sponsored by Portland Parks and Recreation. Started in 2003, No Ivy Day is an event that reduces the amount of mature ivy in the Portland metro area while also educating the public about ivy and its negative impacts on local ecosystems.

See how big the ivy vines can get!

We were thrilled to participate in this city-wide effort by hosting not one but two ivy removal sites! One group meet at the Oak Creek HOA, a brand-new site for TCWC, and the other was at Arnold Creek, an important tributary to Tryon Creek.

We had 16 total volunteers (eight at each site), which included a nice mix of local neighbors, repeat volunteers, and a few of our board members! After some coffee and an introduction, our volunteers set to work. Rain clouds loomed overhead but (thankfully) held off the entire morning, giving us nice, cool working conditions. The terrain was steep and slippery but that did not deter our volunteers. By noon, we had removed  ivy from over 90 trees (30 at Oak Creek, 60 at Arnold Creek)!

Ivy that climbs trees is a concern for two reasons. First, if left long enough, the ivy will eventually kill the tree. From the perspective of a watershed, trees are essential to provide habitat for wildlife and to shade creeks and rivers to maintain healthy temperatures for aquatic life. When water gets too warm, fish and other species cannot survive. Second, once ivy starts to climb upwards, it is able to fully mature, flower, and spread its seed. By removing it from trees, we are slowing down the plant’s ability to reproduce.

To remove ivy effectively from the trees at our sites, we used the “lifesaver” technique:

The lifesaver method takes a little bit more time but is very effective in protecting each tree from ivy invasion. Do you have an ivy covered tree in your yard? Try this method and help remove ivy in your own area – all you need is hand clippers and gloves (although a saw and grubbing tool can be handy, too).

No Ivy Day October 25

What: Tree Ivy Removal

When: Saturday, October 25, 8:45 am – 12:00 pm

Where: Oak Creek HOA, located at the intersection of Vesta Street and Oak Creek Drive

What to bring: Pants, closed-toe shoes, weather-appropriate clothing, water bottle

What will be provided: Coffee, snacks, tools, gloves

Tryon Creek Watershed Council will be hosting a work party for No Ivy Day on October 25! If you are unfamiliar with No Ivy Day, it is an annual ivy removal event in Portland started in 2003 focused on providing stewardship opportunities in our beloved natural areas while raising awareness of the challenges they face.

As many of you know, ivy is incredibly invasive and prevalent in the Portland metro area. To learn more about English ivy and its harmful effects on ecosystems click here. We will be holding our work party at the Oak Creek HOA, located in the Oak Creek neighborhood in southwest Portland. This will be our first work party at the site so it will be great to have a lot of helping hands to kick off this project!

Following the work party, the City of Portland is inviting all volunteers to a post-work celebration at  the No Ivy League Field Headquarters in Forest Park from 12:30pm-2:00pm . Enjoy refreshments, listen to special speakers, and mingle with other volunteers.

We hope to see you at this great event! You can register at the No Ivy Day website here.

Deer-Coyote Invasive Removal

On Saturday, September 27, 19 volunteers showed up to the confluence of Deer and Coyote Creek (tributaries to Tryon Creek) to help remove invasive periwinkle and ivy. TCWC partnered up with SOLVE for their 30th annual Beach and Riverside Clean Up Event, a state-wide volunteer day to help improve Oregon waterways. We had a variety of volunteers show up, including PBS Engineering and Environmental, Wells Fargo Advisors, and a few neighbors and high school students from the local neighborhood.

After enjoying a brief introduction from SOLVE and TCWC, the volunteers got down to business. Using hand cultivators, our volunteers pulled out invasive ivy and periwinkle. Even with the cloud cover, we were all breaking a sweat. A few hours later, a 60 x 145 foot area of invasives had been cleared. You can see the results in our before and after photos:

Thank you to SOLVE for partnering with us for the event! They hosted a total of  4,700 volunteers state-wide that made the following improvements to Oregon’s beaches, parks, neighborhoods and waterways:

  • Removed 52,200 pounds of trash and recyclable material from beaches, rivers, neighborhoods and natural areas
  • Planted 286 native trees and shrubs in parks, on school grounds and in natural areas
  • Removed invasive non-native vegetation from approximately 3 acres of land

And a big thank you to our hard-working volunteers! They made quite the difference at the Coyote-Deer Creek confluence and it is now ready for some native plants this winter.

Pedalpalooza Tryon Restoration Bike Ride

We had so much fun last year, we’re doing it again. The Tryon Creek Restoration Site Bike Ride will be a part of Portland’s Pedalpalooza on Saturday June 14th.

Checking out our watershed by bicycle is a great way to viscerally experience the subwatersheds, the importance of trees, and the difference between urbanized upper watershed and lower watershed parks. We will bike between several restoration sites to showcase some of the restoration work being done in the Tryon Watershed. This year we will visit sites on 4th Avenue (including an art open house with a sculpture garden adjoining the park and restoration site,) the major fish passage barrier at highway 43, an older restoration site on Nettle Creek, and others to be determined.

June 14th 12:30-4:30.  More information and signup here.

Paddle on the Willamette with TCWC!

Join the Tryon Creek Watershed Council for a kayak tour of several urban stream confluences with the Willamette River. We will launch from Jefferson St Boat Ramp at nine AM, paddle to Tryon Creek, past the Riverview tributaries, and to the mouth of Johnson Creek. Biologists and restoration professionals will discuss the importance of these tributaries to salmon and lamprey that migrate through the Willamette River system and through the heart of Portland. The mouth of Tryon Creek and the mouth of Johnson Creek both have had major restoration projects, which we will be able to visit. The Riverview streams come out of a newly acquired city Park property.

Can’t come? Read this report about the fish monitoring of the restoration project at the mouth of Tryon Creek.

Participants will need to bring their own kayak, life preserver or rent from us through our partner, Alder Creek Kayak for $35. A limited number of kayaks are available courtesy of Next Adventure on a scholarship basis- inquire if the $35 cost is a hardship. Bring water and snacks. We plan to return to the boat launch by 12 noon. Please check the Tryon Creek website for more information on the event. Registration below is required.
