Congratulations to 2017's Golden DBH Award Winners: The DiCarlos!

Urban Forestry Honors Two Extraordinary Volunteers for Their Contributions

The DiCarlos receive their award, mounted on the wood of a former Heritage Tree

A package deal, we couldn’t honor one DiCarlo without honoring both! Greg and JoAnne have been dedicated Tree Inventory volunteers since 2015. JoAnne was new to Portland in 2015 and signed up to volunteer for her neighborhood’s street tree inventory with her husband, Greg, as a way to get familiar with the neighborhood. Together, Greg and JoAnne went to all 4 neighborhood workdays and took home homework sections to complete on their own time. They ended up inventorying about half of the Buckman neighborhood on their own!

In 2016, the DiCarlos went through team leader training and led teams through data collection for the street tree inventory. New to tree id in 2015, they worked on honing their identification skills by borrowing reference guides, collecting samples for comparison, and asking great questions at work days. 

2017 saw the introduction of the Parks Inventory, with new data collection techniques, different equipment, and the new goal of identifying every tree to species instead of genus. JoAnne and Greg took the challenges in stride. Although they were apprehensive at first about the clinometer (used to measure tree height) and collecting data on iPads instead of paper sheets, they excelled, teaching the new techniques to numerous novice volunteers over the course of the summer.

The DiCarlos input collect inventory data in Berkeley Park

Greg and JoAnne came to ten workdays during the 2017 inventory season--half of all scheduled events. They took public transportation to get to inventories all over the city and even made it by bus from Buckman to Cathedral Park for a Wednesday evening workday! Inventory staff could always rely on the DiCarlos to arrive ready to work, and to show newer volunteers the ropes. 

Although the equipment used for the Parks Inventory made it difficult to assign homework, JoAnne still sought out additional opportunities to inventory Portland’s trees and partnered with inventory staff in her free time to inventory a small park property in her neighborhood. Greg and JoAnne are looking forward to spending the winter learning how to prune trees with Friends of Trees and attending as many Urban Forestry workshops as possible, and Urban Forestry is looking forward to having them back as team leaders in 2018! Congratulations DiCarlos!

Interested in learning more about volunteering for the urban forest? Join us at the Tree Summit on November 4th to hear results from this year's inventory as well as other opportunities to plant, prune, and advocate for trees in Portland.

Tall Douglas firs flank Hazelwood’s water tower off NE 117th and NE Holliday.

Clustered stands of Douglas fir are defining features of east Portland neighborhoods like Hazelwood. These tall firs stand on both private property and public rights of way providing towering shade and numerous environmental benefits year-round.  Their environmental benefits aside, these trees are also central to the area’s cultural history and credit a nineteenth-century naturalist.

Many of east Portland’s neighborhoods are built amongst groves of Douglas fir. 

The tree’s common name honors David Douglas, a Scottish botanist who spent several years in the 1820s traveling the forests of the Pacific Northwest collecting plants and seeds for the Royal Botanical Gardens at Kew. Douglas, satchel on his back, tromped through the Columbia River Gorge and deep into the interior Norwest and California cataloging and classifying more than two hundred plants and animals he encountered—many of having names that credit him.

Douglas took several trips to the Northwest in 1825 – 1827 and 1829 – 1832.

For all his Pacific Northwest contributions to Linnaean taxonomy, a strange mystery tree stumped him.  Its needles bore a resemblance to the yew, its bark like the hemlock, wood of a larch, and cones similar to a spruce. Douglas thought it “one of the most striking and truly most graceful objects of Nature.” His predecessor, Archibald Menzies, had encountered it in 1793 off Vancouver Island and Aylmer Lambert classified it as Pinus taxifolia in 1803. Douglas dedicated the first chapter of his monograph Some American Pines to a robust discussion on classifying this mysterious and ubiquitous tree of the Pacific Northwest. Now known as Pseudotsuga menziesii, this false hemlock’s Latin name honors the European collector Menzies, while the common name, Douglas fir, on the honors David Douglas for his shipment of seeds back to the Kew Gardens.

David Douglas described the cones as “ovate, pointed pendulous in clusters at the extremities of the twigs.”

Today, most Douglas firs in east Portland are not old growth and it is unlikely that Mr. Douglas traveled directly through this area, instead preferring a speedy canoe on the Columbia. Instead, these trees are second and third generation regrowth from the twentieth century. At that time, this area was a rural farming community with scattered grange halls and schools acting as community centers. Farming families often set aside portions of their farms for woodlots, letting these firs grow to be harvested for firewood, building, and as windbreaks from the infamous east winds.  In the 1950s, the area experienced a housing boom and affordable Ranch-style homes were built among the remnant woodlots with larger backyards and no sidewalks, which gave the trees ample room to grow.

 The Starkwood development listed its “oversized tree studded lots”
as a primary selling feature in this June 30, 1957, Oregonian advertisement.

These suburban neighborhoods were part of unincorporated Multnomah County.  In 1950, the atomized communities of Gilbert, Russellville, and Powellhurst combined as Union School District. In 1952, the school board met and decided to rename the district after the Scottish botanist David Douglas because of the abundance of these firs in the community. The trees were a cultural symbol that unified the district.

Many residents note they “live in David Douglas” because of the trees that helped name their school district. 

Generations of residents in the David Douglas School District have spent their lives under these towering fir groves. The trees are defining features of this part of east Portland and offer an important reminder that the development of affordable postwar suburban housing also considered giving room for these trees to grow. Additionally, the state of Oregon has recognized the Douglas fir as the official state tree since 1936. Today, these trees still hold a significant place in the neighborhood's identity.

Ventura Park Has Long Been a Quiet Stopping Place Off Stark Street

Join Portland Parks & Recreation Urban Forestry to map, measure, and identify all of the trees in Ventura Park!

Ventura Park’s development along Stark Street wasn’t accidental. A short history of the landscape reveals that it has long been kept as an open space by individual citizens over the years.

A post-1854 Baseline Road 7-mile marker sits in the
southeast corner of Ventura Park, E. Stark and 117th Ave.

The park contains one of the state’s oldest monuments: A stone mile-marker installed sometime after 1854. During that time, the area was mostly small farms and Donation Land Claims. Local farmers wanted a road to get their crops to Portland markets. Clackamas County officials (Multnomah County was later carved out of Clackamas and Washington Counties) agreed to build Baseline Road along the Willamette Baseline, which later became Stark Street.  

But the road is even more significant. All land in Oregon is measured from this line and road. If you live in the Pacific Northwest, then your land’s legal description is either north or south of it. After 1854, road builders set a series of stone obelisk markers every mile from the east bank of the Willamette River at the Stark Street ferry all the way out to the Sandy River. The markers helped travelers estimate their trip in horse carts down the dusty and bumpy Baseline Road to and from Portland. Ventura Park contains mile marker “P-7,” meaning that if you were headed to Portland your trip had seven more dusty miles to go till you reached the ferry. Odds are that many a farmer took a break here on their trip to and from Portland!

One of three 1911 -1912 Ventura Park addition plats.

The land that contains the park was prime farmland with great road access for a century. However, changes were underway in 1911.  That year, Thomas and Anna Spillmann, and L. R. Lewis took their farmland just south and east of the park and platted a neighborhood development. Speculating that the city would grow east, they created the Ventura Park plat in unincorporated Multnomah County by dividing their land into 29 blocks of 2,500 square-foot lots. Sales were slow, with homes popping up in after the 1920s. But for the most part, lots remained vacant until after World War Two. 

Ventura Park in its early phases as a Multnomah County Park, May 1960.

Yet, the land where the park now sits remained farmland. Owned by Victor and Helene Welbes, the couple operated a small berry patch with prime visibility on Stark Street. Car travelers down Stark Street might have pulled over to buy some berries in the summer.  By the 1950s, the Welbes increasingly found their farm surrounded by a fast-growing post-war suburban neighborhood, and growth necessitated new schools and infrastructure. So, in 1959 the Welbes sold their farm to Multnomah County for a park and school.

The Oregonian, March 29, 1963.

In 1963, Multnomah County selected the land acquired from the Welbes for a “Showplace” park in the county’s new neighborhood park program. Pooling federal grants with local schools and parks funds, a new program connected county parks with schools in unincorporated areas to help serve residents outside the city. Although innovative, the program constantly lacked funds and disagreements over maintenance between the county and school district ensued. Still, Ventura Park and the adjacent Ventura Park School were named for the nearby neighborhood, signaling the belief among officials that people outside the city still deserved places to live, play, and be educated near where they lived.

County officials hired landscape architect David E. Thompson to design Ventura Park’s landscape and facilities. Thompson’s budget of $113,537 dedicated $11,000 to the planting of trees and shrubs, with an impressive array of deciduous and evergreen specimens. Planting maps and records show Thompson wanted 129 trees planted in the park, but the records do not contain the final planting list. The upcoming Ventura Park Tree Inventory will not only identify every tree in the park but will also help us understand what trees Thompson may or may not have planted.

When Portland annexed areas of east county in 1986, Portland Parks & Recreation assumed management of Ventura Park. The following year, the annual “Fun-O-Rama” carnival started in the park and many summer concerts have since occurred here over the years. The park itself has changed hands many times. But from farms, fields, to a park, for over 150 years this piece of land has been an important resting place along one of the region’s oldest continuously used roads.

Urban Forestry Stewardship Support in Action - Part 2

Featuring the King Sabin Community Assistance Project

In this two-part blog series, we highlight the achievements of Neighborhood Tree Teams that have recently applied for and utilized funds available through the Urban Forestry Stewardship Support Program (we are currently accepting suggestions for a better name). PP&R Urban Forestry offers financial, in-kind, and limited staff support for tree stewardship events - presentations, workshops, community projects and outreach activities for Neighborhood Tree Stewards and Neighborhood Tree Teams. To learn more about Stewardship Support, please check out this link.  

The following article was submitted by King Sabin Tree Team.

King Sabin Street Tree Community Assistance Project 2016-17

The King Sabin Tree Team obtained funds through three organizations in order to accomplish project goals for the 2016-17 Community Street Tree Assistance Project. This project provided full funding for six properties (three in King, three in Sabin) to remove dead or dying street trees and replace with healthy new trees, through a permitted removal/replant process. Funds used for this project are summarized in the table below.

Source Award Amount
Sabin Community Assistance Grant $1,000
East Mult Soil and Water Conservation District SPACE Grant $1,500
PP&R Urban Forestry Stewardship Support $800
Total: $3,300

Northeast Coalition of Neighborhoods (NECN) acted as fiscal sponsor for the Sabin Community Association (SCA) and East Multnomah Soil and Water Conservation District grants. In addition to funds secured for this project, PP&R Urban Forestry waived the $35 removal/replant permit application fee for five properties (the sixth property had a permit in-process prior to signing up for the project). Friends of Trees provided ten replacement trees at no cost. All organizing and outreach work was conducted by Tree Team volunteers. Green King also provided volunteer support.

All project funds (less $125 for NECN 5% admin fee) were used for arborist services to remove trees and grind stumps. Log rounds were left on-site as a cost savings measure, or offered to community members and successfully removed. ISA certified Pacific Standard Tree and subcontractors, all residing in the project area, provided arborist services. King Sabin Tree Team members provided approximately 45 volunteer hours for project coordination, canvassing, completion and submittal of permit applications and consent forms, and coordination with Friends of Trees and project participants, in addition to tree planting.

Fliers were posted around the neighborhood, and notices were posted on the Sabin Community Association and Green King Facebook pages, as well as Next Door. Canvassing occurred in December 2016, using street tree inventory data to identify trees in dead or poor condition and Portland Maps data to match properties likely occupied by income-qualifying residents. Project participants self-identified as having a financial barrier to street tree removal and replacement.

Tree Team members completed the Urban Forestry street tree removal/replant permit applications and acted as liaison with Friends of Trees to order trees. Removals were timed so that replacement trees could be planted by Friends of Trees and community volunteers on the scheduled Friends of Trees planting dates, February 18 for King, and March 4 for Sabin. Additionally, project participants signed a consent form provided by Urban Forestry, agreeing to tree establishment care, including two years of weekly summer watering. King Sabin Tree Team members will follow up with project participants to assist with watering if needed, and monitor establishment.

The table below provides information on trees removed and trees replanted. Originally, the Tree Team assumed that more properties would be included in this project. However, canvassing efforts did not produce the expected response. Additionally, 4 removed trees were exceptionally large, necessitating a significant proportion of fund allocation for stump grinding. Overall, project goals were satisfied through offering support and financial assistance to community members unable to bear the  cost of tree removal, and by improving neighborhood canopy health, viability and watershed function through removal of dead trees and diversification of new plantings.

Urban Forestry Stewardship Support in Action - Part 1

Spotlight on the ReLeaf Program of the Albina Neighborhood Tree Team

In this two-part blog series, we highlight the achievements of Neighborhood Tree Teams that have recently applied for and utilized funds available through the Urban Forestry Stewardship Support Program (we are currently accepting suggestions for a better name). PP&R Urban Forestry offers financial, in-kind, and limited staff support for tree stewardship events - presentations, workshops, community projects and outreach activities for Neighborhood Tree Stewards and Neighborhood Tree Teams. If you are unfamiliar with this program, please check out this link.   

The following article was submitted by Heather Wheeler, a founding member of Albina Neighborhood Tree Team (ANTT);

ReLeaf for Neighborhood Trees in Boise and Eliot!

Community trees are a public resource, and caring for them should not be a burden for low-income homeowners. This is a costly problem to solve, especially in neighborhoods of North Portland where about 10% of trees inventoried are dead or in poor condition.

The Albina ReLeaf Program began in January 2016 with the intention of enhancing the quality and diversity of trees while reducing the burden of care on low-income homeowners. It was a modest start, with the removal of six dead trees and eight healthy replacements. This year, the program expanded to remove and replace over four times as many dead and dying trees, with 25 removals and 38 plantings. This year's event occurred in March and included 18 properties. As for the trees, new plantings represented 13 genera with nine native species and one large conifer. All trees were selected for tolerance to urban conditions and suitability to each site. Among the trees removed, there were 23 cherry, one hawthorn and one highly invasive tree of heaven (Ailanthus altissima).

Tree Removal by Treecology

Several partnerships made the ReLeaf Program possible. The organizing group, Albina Neighborhood Tree Team (ANTT), was funded by the Partners in Conservation Grant from East Multnomah Soil and Water Conservation District, along with Stewardship Support from Portland Parks & Recreation Urban Forestry. All permitting and paperwork was handled by ANTT, making the whole process a snap for participants. Treecology offered professional arborist services, removing the dead or dying trees to make way for more appropriate tree species. Friends of Trees supplied and planted these trees, intended to be community assets for several decades. Additionally, the Northeast Coalition of Neighborhoods (NECN) was a very supportive fiscal sponsor, assisting with the many financial aspects of this whole process.

Tree planting with Friends of Trees

This is the first program of its kind to take place in Portland, and has already served as a model for other Portland neighborhood groups to begin helping low-income homeowners plant and maintain a healthy urban forest in more areas around town. The goal of expansion is well underway in just the second year, as ANTT joins forces with other surrounding neighborhood tree teams and forges new partnerships with like-minded organizations.

Reducing the abundance of dead or nearly dead cherry trees has been a major focus of the ReLeaf Program in the first two years, with future objectives aimed toward reducing invasive or nuisance tree species, as well. Newly unfurling plans target a broader ReLeaf area, and aim to offer a menu of subsidized tree care services to community members who face financial barriers to tree care. Exciting plans are also in the works to introduce a new component of cutting sidewalks to make space for planting larger trees in coming years. Realization of these plans will depend upon availability of funding and community support. Consider joining us, or the tree team in your neighborhood, to lend a hand.
