An abundance of shovelers helped to break ground at the official “ceremonial” start of Merrill Hall reconstruction held on October 1 . Led by UW President Lee Huntsman, CFR Dean Bruce Bare, Miller Foundation Board Members Carey and Winlock Miller, Members of NHS and the Seattle Garden Club, Master Gardeners, staff, faculty, and students of CUH, and many others, much dirt flew from the site of the new building. CUH Director Tom CFR Dean Bruce Bare> Mi,ler Foundation board member Winlock Miller, and UW President Lee Huntsman dig in at Hinckley thanked everyone who gave support the October I Merrill Hall groundbreaking event. during the long process to rebuild and shared the relief of finally seeing the building rise from the ground. This happy occasion was long-awaited. CDK Construction Services, general contractor on the project, is working hard to maintain the 1 1 -month project schedule. The building is scheduled for official move-in shortly before the start of Fall Quarter in 2004. The final project budget totals $7.2 million. This includes money from the UW and state of Washington, plus $1 million in support from private donors. When finally finished, the building will be 3000 square feet larger than the original building. Construction can be clearly seen as the new Miller Library starts to take shape along the CUH entry driveway. From the start, staff, faculty, and students pushed to showcase “sustainable” building design and construction. This was intended to express the Center’s, and the College’s, mission of sustainable management of natural and urban landscapes and resources. To that end, the University has committed to following the LEED certification process created by the U.S. Green Building Council. LEED stands for “Leadership in Energy and Environmental Design”. If the Merrill project achieves certification, it will be the first building on the UW Seattle A concrete truck pumps concrete into new foundation at Merrill Hall. the campus to do so. Anyone can apply for LEED certification for a commercial building, but it takes a careful understanding and LU CC D h -I D U h CC 0 X z < CO D commitment during all aspects of the design and construction process to actually achieve it. The Merrill project team is hoping to meet the LEED challenge by recycling construction waste, maintaining healthy air quality, using certified wood and local building materials, installing water-saving devices, and recycling roof runoff into the irrigation system, as a start. As a true commitment to building a sustainable building, several members of the project team have taken a special exam to qualify as “LEED Accredited Professionals ’. The aim is to increase the knowledge base of people in the green building industry.

In 1915, the tough, wily pioneer known as Cougar Annie arrived on the coast at Boat Basin, in the northern reaches of Clayoquot Sound. The five-acre garden she cleared in the rainforest became her lifeblood, her burden and her passion. For nearly seventy years she lived here, creating a garden nursery with an astonishing variety of shrubs, perennials and fruit trees, and in the process bearing eight children C i • and outliving four husbands. The garden was doomed to die with - her until Peter Buckland returned it to life and Margaret Horsfield wrote a prize-winning book on it. Together they will bring back to life this amazing woman and the garden she created. Heronswood Nursery will open to the public from 9:30 a.m. to 3:30 p.m. on Friday, February 13 and Saturday, February 14, with an admission price of $7.50 per person, to benefit the Elisabeth C.

The land for the dump was exposed when the Montlake cut was completed and Lake Washington was dropped eleven feet in 1916. Filling in of the mud flats with rubbish and other materials began in the 1920s. The City of Seattle operated the site as a landfill until it was closed and graded flat between 1968 and 1970. The fill surface was seeded with clover and with a non-native grass mixture to prevent erosion and eliminate dust. Some fruit trees were planted along Wahkiakum Lane, and an occasional pine tree may be found on the site today, dating from this period. Ongoing restoration in the Union Bay Natural Area has converted the former landfill into a haven for birds and other wildlife. Over the years, various structures were built on the fill in an attempt to realize the promise of turning it into “a usable part of the campus” '. A structure was built at the golf driving range and a clubhouse was built at the old baseball field which was at the corner of 45th Street and the current Mary Gates Boulevard. Both suffered from foundation cracking caused by unequal settlement of the fill. Light standards installed on pilings in parking lot E5 (the “dime lot”) showed 4 to 5 feet of settlement as the lot sank and the pilings did not. The response to settlement as it occurred over much of the site was to add more fill to level the soil surface. Because of the ongoing settlement, the University gradually backed away from building any but the lightest structures on the fill. CUH Takes on Management of UBNA I he Center for Urban Horticulture was opened in the mid 1980s, and the staff of the Center was given the responsibility for managing the 54 acre part of the fill east of University Slough. Because there were no guidelines for the management of the area, and because competing University groups and citizen groups had different visions for the site, in 1986 a committee chaired by Eugene Hunn was appointed by the University and was charged with developing guidelines for the use and management of the area. The committee proposed that the land be used to support the University’s mission of teaching, research and public service, and that the goals should be to improve habitat and to maximize native biodiversity. The last section of the management guidelines, under the heading of “A Vision for the Future”, suggested that the newly named Union Bay Natural Area could become a national and international model for ecosystem restoration, with the active participation of a cross-section of the different disciplines at the University. CUH Students and Faculty Begin Restoration of UBNA In 1991, active restoration began at Shovelers Pond (0.5 hectare) on Wahkiakum Lane. Covered with purple loosestrife and used by local middle-schoolers as a place to ride mountain bikes, the pond was actually a vernal pool, drying up for six months each year. Students, faculty and staff began a three year project to grub out the loosestrife, build a berm at the north end of the pond, and haul in logs along Wahkiakum Lane to discourage bikes from speeding down the hill from the north and launching into the pond. In 1993, a graduate restoration class removed a large area of blackberries near the UW corporation yards. They then planted snowberry to see if this replacement of invasives by natives could be effective. For several years the snowberry did little, but then it exploded with growth and has formed a chest high population. In 1994, faculty and students experimented with planting native prairie species, mainly Roemer’s fescue, in a 1 hectare area just west of the CUH parking lot. Mounds were built to mimic the naturally mounded prairies of South Puget Sound. Experiments were set up using soil modifications and mulches. It became apparent that the native herbaceous prairie species were stress-tolerators, but the invasives really liked adequate moisture and better soils. This research area is now being maintained as Wahkiakum prairie, and it has flourishing camas, potentilla and Roemer’s fescue mixed in with the non-native pasture grasses that cover the Natural Area. It was recognized in the early part of the 1990s that the Natural Area was becoming dissected by too many social trails. There was a generally established loop trail that left Wahkiakum Lane just east of Shovelers Pond and followed the Lake Washington shoreline to rejoin Wahkiakum through parking lot E5. There were also hundreds of anastomosing pathways that put people and wildlife in conflict. The decision was made to make the loop trail the desirable choice for walkers by giving it an improved surface, first with bark (1996), and subsequently with gravel (1999). The western connection with Wahkiakum Lane was moved away from a path through the seasonal wetland to t-he south of E5, to a dry, all-season path to the east of E5. Garry oak seedlings were planted in three locations in 1995 as part of a class and a thesis project. In two locations, the slow-growing oaks were overwhelmed by Himalayan blackberry. In the third location, southeast of Shovelers Pond, the oaks now flourish and have reached 2 to 3 feet in height. The rapid advance of blackberry across the natural area was quantified by measuring its coverage in sequential aerial photos, and a decision was made to control it by repeated mowing. Though they provide some resources for wildlife, blackberry bushes form monocultures that eventually minimize diversity. Since 1998, the infestation areas have been mowed after the general nesting season has passed and after the grasses have dried up during the annual summer dry period (June through October). Since the grasses have senesced by this time, and because they have basal meristems, they lose little stored photosynthate and are not negatively affected by the mowing. The blackberries, on the other hand, are repeatedly mowed down to the ground and are forced to compete every spring with increasingly robust grasses. Mowing is done at This map of the Union Bay Natural Area shows the area being managed by CUH students and faculty.

Parking Lot Restoration using Prairie Species In 1995, one third (approximately 0.675 hectare) of parking lot E5 was returned to the Center for Urban Horticulture to be converted back to natural vegetation. Because years of adding gravel to the lot had left a deep layer of coarse rock (5-10 feet deep), it was apparent that the area would be droughty and nutrient poor. Because native Puget Sound prairies are naturally found on gravel outwash, it was proposed that native prairie species be installed, and that the area be restored as a prairie. Research on the Natural Area had shown that mounding produces soil conditions that are drier in both summer (causing a more stressful environment that favors prairie species) and winter (reducing the drowning of plant roots by the shallow water table of the landfill cap). To simulate the natural mounded prairies of the Puget Sound region, students in one of our restoration classes dug up gravel from the parking lot, piled it up, and planted prairie species over the resulting mounded landscape. The Roemer’s fescue, potentilla, wild strawberry, and several other prairie species immediately established and have dominated the site to this day. Classes continued to experiment and work with this prairie site for two more years. One problem was that non-native grasses like creeping bentgrass continually invaded from the deeper soil sites around the perimeter of the old parking area. So in 2001, a class planted a native shrub buffer (of snowberries, roses, ocean spray, red-flowering currant) around the edge of the new prairie. Going up one life-form is a common way of dealing with problematic invasive plants (trees beat shrubs, shrubs beat grass), and combined with liberal applications of wood chip mulch as a top-dressing, it is proving to be an effective technique for suppressing grass and blackberries while the native shrubs get established. Alter five years of working on the restoration of parking lot E5 and the area to its east and south, classes will be moving on next year to an area just east across the loop trail, to plant a deciduous forested ecosystem. Lessons Learned During UBNA Restoration In 2001 an experimental series of plots was established to test the most effective method for site preparation for the installation of shrub species. Half the plots were herbicided and tilled, and the other half was covered with 10" of wood chips. Bare root snowberry and other shrubs were planted in the winter into both treatments. In order to plant into wood chips, furrows were dug down to mineral soil and the seedlings were planted in the soil. Among its other virtues on this dry summer site, the mulch created much moister soil conditions with moderated temperatures during the growing season, and the mulch sites have had high survival (80%) and good growth of shrubs, while the tilled sites have very low survival and poor growth. Experiments like this one, and experience with restoration projects, have convinced us of the value of heavy mulching on restoration sites to suppress weeds and to keep the target species alive without additional watering. Another lesson learned from the parking lot E5 restoration is the dynamic nature of the surface of the landfill. There are currently two substantial vernal wetlands just east of the parking lot, and these wetlands did not exist in 1990. Where we planted prairie plants in 1998, we can now successfully install wetland bulrushes. Increased interspersion of wetlands and uplands is not a bad thing, however, and we simply need to be aware of the swiftness with which the topography and resultant hydrology are changing. Ribes sanguineum and other native species were planted around the perimeter of the restored prairie Oregon State University ♦ Capstone Restoration Classes work in East Basin In the autumn of 2000, a capstone restoration class (autumn, winter and spring quarters spent on one project) was started, and each year since then one capstone group has worked in the area that we call the east basin. The east basin of the Union Bay Natural Area is the wetland and upland east of the CUH greenhouses, bounded on the east by Surber Drive and on the north by NE 4lSI Street. Before the ravine was fdled to build 41st Street, Yesler Creek flowed through the old Battelle property into Lake Washington at this site. When the Yesler sawmill was operated on what was to become the site of the Center for Urban Horticulture, the east basin was a waterway, and is designated as such on old maps. During World War II, a victory garden was planted there. The lagoon that the remnant of Yesler Creek empties into is a marvelously isolated place with herons, eagles, hawks, and a famous pair of nasty swans. The riparian vegetation just north of the water is well-developed and dense. The problem is the edge of the wetland and the adjacent uplands, which have become overrun by reed canarygrass and blackberries. Students, staff and faculty are now using the restoration techniques that have been developed over the last two decades at the Center for Urban Horticulture to eliminate invasive species and to install native wetland and upland plants in a 0.5 ha area, and create a substantial native buffer for this very important lacustrine wetland system. Working on the Union Bay Natural Area has taught us several good restoration lessons. We work incrementally, and then we protect what we have restored. We are working east from parking lot E5, and west from the east basin site, and we hope those two efforts will someday meet. We do not walk away from a site. This is the city, and the city is filled with invasive plants; restoration requires continued attention. As the restored system becomes more mature, the effort required for maintenance should decrease but will not be eliminated. We use large amounts of selected arborists’ wood chips as mulch. It is free, and if we inspect it to make sure that no English Ivy or other weedy species are mixed in, it is effective. We know that weeds will always be with us and we tolerate a low level of them, but when there is a substantial outbreak we remove them. On our site the plants that usually trigger this reaction are Himalayan blackberry, Scotch broom, reed canarygrass and purple loosestrife. Our students are energetic and engaged, and are very effective in installing restoration projects. But because classes recur with a frequency of only once-a-year, staff members are needed for ongoing maintenance of sites and for 7 monitoring weed outbreaks. 1 Dunn, W. 1966.

Plant Answer Line Questions Continue to send your puzzling plant questions to the Miller Library Plant Answer Line. Here are a recent sampling of questions from gardeners: QUESTION: When should I put dahlias in storage for the winter? Plant Answer Line The Plant Answer Line is open from 9 a.m. until 5 p.m. Monday through Friday. Call UW PLANT, 206-897-5268, or e-mail your question to: hortlib@ii.washington.edu ANSWER: There is constant discussion among dahlia growers as to whether or not dahlias should be lifted before the first frost has occurred. Premature lifting may result in the unripe tubers drying out and shriveling. The value of a prior frosting lies in the fact that growth is halted and the tuber becomes dormant, all the food reserves are stored in the correct state in the tuber and its skin thickens up so is less prone to damage as it is extracted from the soil. Even so, some growers lift their tubers every year at the end of mid-autumn, frost or no frost, acting on the belief that in the dahlia’s natural habitat of Central America, no frost is necessary for the tubers to ripen successfully. Taken from The Gardener’s Guide to Growing Dahlias , by Gareth Rowlands, 1999. QUESTION: What is the oldest living tree? ANSWER: According to the Brooklyn Botanic Garden Gardener’s Desk Reference, edited byj. Marinelli, 1998, the Great Basin bristlecone pine (Pinus longaeva) holds the record for the oldest living tree. A few of these trees growing high in the eastern California mountains are more than 4,600 years old; one bristlecone pine in Nevada thought to be the oldest is said to be 4,900 years old. The growing conditions — cold winters and arid summers — are so severe that the tallest specimens of bristlecone pines are only 30 feet high. QUESTION : I’ve heard about a lawn-removal method that involves smothering it with newspaper. How is this done? ANSWER: Lay down a layer of newspaper 6 to 1 2 sheets deep over the area you wish to transform into a garden bed. Make sure the edges of the newspaper overlap by several inches. This creates a barrier that virtually no grasses (and most perennial weeds) will live to penetrate. Cover the papers with 6 to 10 inches of mulch or composted manure. Thoroughly wet the area and ignore it until spring.That’s it! Your smothered lawn, the newspapers, and mulch will all meld together into a nutrient-rich topsoil that is much deeper than the one you'd have started with after digging up the sod. Taken from the WSU Extension Regional Garden Column, August 5, 2001. QUESTION : I’m confused about when to plant bulbs. They are for sale at the nurseries now but shouldn’t they be planted in the spring? ANSWER: It all depends on the bulb; some are best planted in fall, some in spring, and some at any time of the year! For a comprehensive list of when to plant which bulbs (plus planting depths and flowering times) see Appendix C of Bulbs; A Complete Handbook, by Roy Genders. 9 CENTER FOR URBAN HORTICULTURE WINTER 2004 For recorded informa- tion on Arboretum events and programs, please call 206-543-8800 or visit the Arboretum Foundation website at: www.arboreWmfoundation.org 0 Director’s Search is Underway.

FAX EMAIL REGISTRATION FORM UNIVERSITY OF WASHINGTON CENTER FOR URBAN HORTICULTURE For the Center, this has been a year between the past and the future. Merrill Hall will be one step closer to re-opening and will soon have its floor. The search for a new director to fill the Orin and Althea Soest Directorship is underway once again. After some 17 years of incredible service to the Puget Sound Region and its horticultural community, Mary Robson “retired” in mid-November. The energy and enthusiasm she brought to her position are particularly noteworthy. She also has ensured the continued (and enhanced) presence of WSU Cooperative Extension and the Master Gardeners and the Master Gardener Foundation in the new Merrill Hall. Within days of her retirement, Dr. Paul Gutierrez, WSU Extension Chair for King and Pierce County, left to become Associate Dean in the College of Agriculture at New Mexico State University. Paul brought great personal and organizational skills to the extension office in Renton. He also was able to increase the attention of administrators in Pullman to their distant, western Washington centers. Although the two of them will be greatly missed, their leadership and their attention to the transition for the future will ensure the continued success of the partnership between UW and WSU.
