Open Space Park

The Bridlemile Open Space Park is an undeveloped open space located on the flag lot between 4119 and 4201 SW 58th Ave just north of SW Hamilton.

Together with the undeveloped portions of neighboring properties the Open Space Park (the flag lot with red dot in the center) forms a large open space in the middle of many homes. Areal Photo of the area from Portland Maps

It's filled with tall trees and large variety of native plants that are in fierce competition with encroaching invasive plants such as ivy, Himalyan blackberries, holly, and other non-native plants.

In 2006 the Bridlemile Creek Stewards together with Friends of Bridlemile Open Space Park held the 1st Annual Friends of the Open Space Park No Ivy Day event at the park. And in May of 2007 the 2nd Annual Friends of the Open Space Park No Ivy Day Event was held.

Invasive Removal Events for 2007 are posted on the SWNI Events Calendar, click here for a list of Bridlemile Watershed Events.

Friends of the Open Space Park 2006 No Ivy Day Event

May 6th, 2006 Photographs by Victor von Salza

Six Friends of the Open Space Park together with 5 Bridlemile Creek Stewards and 3 other volunteers (total of 14) rescued about 4 dozen trees from the clutches of ivy, cleared about 500 sq. ft. of ivy from the ground, took down 3 holly trees, and removed a few blackberries.

Greg explained some of the many benefits of removing ivy to Ryan, Owen, and Partrick, and Victor explained how to work safely. Dave and two students came later in the day and removed more ivy and holly after the above photos were taken. In all, a good day.

Friends of the Open Space Park 2007 No Ivy Day Event

May 5th, 2007 Photographs by Victor von Salza

Seven Friends of the Open Space Park together with 6 Bridlemile Creek Stewards and 12 other volunteers from within and outside of Bridlemile (total of 25) rescued about a dozen trees from the clutches of ivy, cleared 1000+ sq. ft. of ivy from the ground, and took down 6 - 5 inch or larger diameter) holly trees, and a stand of Italian Laurel. Kathy Bambeck staffed the sign and information tables, and Kathy Donofrio brought some yummy home baked goodies, Dave Baasch put up signs, and Gus and Claudine Kent who again generously allowed us to access the Open Space Park via their property and foot bridge.

Friends of the Open Space Park Work Page

This page is for Friends of the Open Space Park(OSP) who would like to work in the Park removing invasive plants on their own or in small groups. This work also qualifies for Community Service hours (see below).

Working at the Open Space Park can be a great way to relax after a hard day at the office, a way to get exercise and benefit the environment at the same time, an opportunity to have some peaceful solitude, or engage in conversation with like minded neighbors.

Pulling ivy in the Open Space Park.

If you would like to have others join you while you work there, simply send email to fosp-talk@mlist.swni.org to announce/organize your own work party - outside of the yearly No Ivy Day Event.

While the No Ivy Day Events at the OSP have made a great start, and the areas cleared during those events are doing well, they have not been enough to get the invasive plants knocked back and under control. Your volunteer time of even a few hours, when combined with similar time and effort of your neighbors, over the year will help to accomplish that... and more...

Tools you will need / Tool box location
The tools you will need for removing each type of invasive are described in corresponding sections below. Common to them all are gloves. We hope to eventually have a tool box on site, until then please use your own favorite garden tools. You can also check out tools from the Southwest Watershed Resource Center 503-823-2862, or borrow them from BCS/Greg Schifsky, 503-246-2714 Machetes and hatchets are not appropriate tools to use.

How to rescue ivy from trees
Removing ivy from trees is most important since ivy goes to seed on vertical surfaces and eventually can harm or kill trees. The process is simple and is very nicely shown on the No Ivy League Lifesaver Photo pictorial page.

How to remove ivy from ground
Is described very well and concisely described with pictures at ivyout's How to remove English ivy page. NOTE: Please avoid pulling ivy from steep stream banks unless there is a plan in place for erosion control and replanting with native plants. While ivy is terrible for erosion control (because of its shallow root structure and heavy weight it can actually help cause landslides) bare slopes are even more prone to erosion. On steep slopes limit your ivy removal to cutting any hanging runners.

How to remove blackberries
Is very nicely described with pictures on this How to remove blackberries Step-by-Step Tutorial page.

Other Invasive plants
To Be Determined (TBD) once the ivy and blackberries are under control.

Park boundaries

Together with the undeveloped portions of neighboring properties the Open Space Park (the flag lot with red dot in the center) forms a large open space in the middle of many homes. Areal Photo of the area from Portland Maps. We plan to mark the park boundaries more clearly in future.

Work Site / How to get to the work site
The work site begins along the trail between SW58th and the creek which begins here:

Location of Trail to Open Space Park. Photo by Victor von Salza.
Step thru the portal outlined in red in the photo above and

Beginning of trail to Open Space Park.  Photo by Victor von Salza.
you will find this trail that is part of and leads down to the Open Space Park.

In the area along the trail are number trees that still need rescuing, and lots of ivy on the ground that needs to be removed.

At the creek someone (not the City) has recently made this

Bridge in the Open Space Park.  Photo by Victor von Salza.
"bridge" across the creek. Use caution when crossing this temporary bridge.

The largest part of the work area is to the left of the trail after you cross the bridge, and to the West of the Reister and Kent properites that are East of the creek. If you go too far to the left/south you will come to a fence on the south side. If you go to far West along the trail you will come to a no trespassing sign marking the west end of the park; please do not work or trespass beyond that point.

Arrange for an informative personal tour of the site and demonstration on how to remove invasive plants by contacting:
Steve Mullinax, 503-768-9065
Greg Schifsky, 503-246-2714

How to get Community Service credits for your volunteer time
TBD - who can provide this?

Small Print / Safety First
When working with any tools always maintain a safe distance around fellow volunteers. Always use caution in the Park when navigating the temporary bridge and trails.

Ultra Small Print
Please don't work at the site unless you are willing to sign the following first:

I hereby agree to waive all claims against individual volunteers and organizations arising out of or in any way related to my volunteer work in the Bridlemile Open Space Park. This waiver includes, but is not limited to, claims arising out of removal invasive plants or planting native plants . I agree to hold the project sponsors harmless against all claims as described above. I recognize that this is physical labor and that if the labor becomes too difficult I will change my activity or stop. I should use good judgment based on my physical abilities.

Please copy the above text into an email, and send it, along with your name, address, phone number, email, and if you are under 18 the name of your parent or guardian to: SWNI.org

Thank You! for helping to make the Open Space Park the wonderful place that all we hoped it would continue to be!
