Make Your Mark on the Garden
Help Carve the Cedar Columns for the New Interpretive Shelter
This month and next, the Pomegranate Center and the Arboretum will host a series of workshops for members of the community (aged 15 and up) and supervise them as they sand, carve, and stain the cedar columns for the new interpretive shelter of the Pacific Connections Garden. There will be three Saturday workshops, on August 11 and 18, and September 15, from 10 a.m. to 2 p.m., and three Wednesday workshops, on August 15 and 22, and September 12, from 4 to 7 p.m. All workshops will take place just south of the Graham Visitor Center. For more information, visit the Pomegranate Center Web site.
Public Comment Period Open on the Determination of Non-Significance (DNS) for the Pacific Connections Garden project at the Arboretum until May 10th. 
Documents are now available for public review. The University of Washington, the City and the Arboretum Foundation are working together on three projects to implement the Arboretum master plan. The three projects include the Japanese Garden Entry Structure, the Pacific Connections Garden and the Irrigation Mainline Project.

These two owl babies (owlets) were recently seen peeking out from a snag at the Arboretum.
The snag is a dead bigleaf maple that was trimmed and maintained for habitat – in this case, a family of barred owls.

An Olmsted era monument was raised at the corner of 26th Ave East and Lake Washington Blvd by the Seattle Parks Department. City masons will restore the monument to be as close to the original as possible.
We are
looking for a group of energetic, fun, and dedicated people
who would like to become part of the Arboretum team by participating
in a restoration work party.
The
parties will be held February 11th-12th from the hours of 10aw
3pm each day. Both of these events will be hosted by a team
from the University of Washington Restoration Ecology Network and
the Arboretum staff.
Our main
goals will be to remove invasive plant species (Himalayan Blackberry,
morning glory), and to spread cardboard and mulch in preparation
for installation of native plant species. This is a great way
to build your resume, meet people who care about the environment,
do something positive for your community, and have fun at the
same time.
Food will be provided by Whole Foods, so come out to help your community
and learn about wetland restoration!
If interested in this opportunity we will be meeting at the Washington Park
Arboretum: 2300 Arboretum Drive East, Seattle, WA 98112

Garden Loosestrife in the Arboretum

Garden loosestrife, Lysimachia vulgaris, is a Class B noxious weed in the state of Washington and King County. King County requires control of this weed. It establishes itself in wetland areas and is very aggressive and invasive and is a serious threat to the native character of our wetlands. It spreads by rhizomes and seeds.
At the request of the King County Noxious Weed Board the Arboretum will be spraying the garden loosestrife during the latter part of August, while the plant is in flower, in hopes of gaining control while the patches of it are still relatively small in size. Combining the use of GIS maps provided by King County Noxious Weed Control Board and scouting by boat we have counted 18 sites from the eastern tip of Foster Island to MOHAI, a sizeable area around the eastern-most boardwalk of Foster Island, and 3-4 sites at the Center For Urban Horticulture. These areas cover a maximum of 12,000 square feet total. This is an estimate and the actual area treated may be less.
We will by using the Triclopyr amine herbicide ‘Renovate’ formulated to be used in aquatic situations and approved by the Dept. of Ecology. We have chosen to use this because it is a selective herbicide and will not affect the monocots surrounding the broadleaf garden loosestrife, which will help provide competition against any possible garden loosestrife seedlings.
Department of Ecology requires that any aquatic pesticide application have a special permit. We have obtained permit coverage and are following all rules.
Spraying will be done by two aquatic licensed applicators, assisted by one or two others. We will be following permit regulations as regards posting notification and will be posting regulatory signage and interpretive signs at the Waterfront Activity Center, MOHAI, both ends of the Foster Island trail, and at the grassy point on the eastern edge of Foster Island. In addition, each site that is sprayed will be flagged with a ‘pesticide application’ marker. Signs will go up the morning that we spray and be removed the following day.

Bush School Volunteer Project at the Japanese Garden


On May 3rd, 2004 Bush High School students weeded and mulched some new Japanese Garden plantings near the parking lot on Lake Washington Boulevard as a community service project. As always, their hard efforts are much appreciated!
Earth Day Volunteer Project with Seattle Preparatory School

On April 7th, 2004, Earth Day, over 80 Seattle Prep highschool freshmen pulled up ivy and other invasives along the Boyer/LWB crosswalk intersection on the Pinetum side of WPA. This is the second year Seattle Prep has volunteered their services in the Pinetum area. The WPA City Parks grounds crew assisted in organizing this community service school project and have also recently installed new paths to better serve pedestrian and bike traffic more safely around crosswalk. A huge thank you to Seattle Prep for their hard work in cleaning up this area in WPA on Earth Day!
Arborists Volunteer in Celebration of Arbor Day

Sponsored by Plant Amnesty in celebration of Arbor Day, several local tree companies helped the WPA tree program by volunteering their services on March 25th and 31st. On the 25th, 4 arborists representing two companies aerial pruned (deadwooded) the Cedrus grove located in the Pinetum. On March 31st, 9 arborists representing 5 companies aerial pruned (deadwooded) 9 oaks in our Oak collection. A big thank you goes out to all the arborists who participated in this project!
