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.

One of many beds of Trillium one can see in Spring. Note the ivy (in upper lefto of photo) that is beginning to take over as ground cover. Photo by Victor von Salza, April 2006
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.
