Congratulations, you helped plant 50,000 trees and native shrubs last season! Now what? Good thing Friends of Trees isn’t just a tree planting organization–tree care is also on the list because we want the trees we plant to survive and grow and thrive.
It works.The survival rate for urban trees planted the Friends of Trees way, together, with guided post-planting care from our Tree Team, is 97% (based on Portland street trees planted last season). For the subset of trees we’ve been monitoring for nine years since planting it’s an 88% survival rate.
Our trees planted in natural areas also have strong survival rates, especially given some very challenging conditions; for example, some planting sites are not accessible for watering; some plants get eaten by wildlife; humans sometimes trample or vandalize; etc. Some studies indicate that an acceptable minimum survival rate for riparian area restoration plantings is 50%, so our survival rates of 81% in year one and 70% after three years are particularly impressive.
How do we help trees thrive?
We water. We prune. We mulch. We visit and assess. We do this for the street and yard trees planted through our Neighborhood Trees program as well as for the native trees and shrubs planted in our Green Space program.
As part of our Neighborhood Trees post-planting care, we:
- continually share information with tree-recipients about how much water, mulch and pruning trees need;
- deliver and apply free mulch soon after trees are planted;
- offer a summer watering service for a reasonable fee;
- have a Summer Inspector program where trained volunteers visit all newly planted trees twice in the first summer after planting to inspect for tree health, leaving tree care info for the tree recipient.
- have a longer term monitoring program where we visit subsets of trees planted anywhere from two to 10 years ago, to track health and growth;
- prune trees throughout the year (except for a few weeks in the spring and fall when trees are budding or dropping leaves). We rotate neighborhoods each year and focus most of our work on low income, low canopy and/or historically under-served communities.
Did we mention we prune? Last season we pruned more than 1,600 street trees, which is vital toward proper growth and really helps them survive wind, snow, and ice storms.
Our Green Space program also cares for the new trees and shrubs planted in natural areas, and we do this for up to 10 years after planting. The team is often joined by employee volunteer groups who help with summer maintenance tasks such as watering, mulching, and weeding (also called “day-lighting” since we’re clearing space around new plantings to provide for more light and air, and to reduce competition with weeds). We also assess for survival and replant when necessary.
Volunteers help with this! We train volunteers to inspect and prune trees, and volunteers are crucial to effectively mulching thousands of new trees at tree care events.
All told, we care for and monitor more than 54,000 trees a year!
We’re spreading the good word about trees.
We spend much of the summer spreading the word. Our Volunteer & Outreach Team, aided by dedicated Tree Team Ambassadors, attend events, festivals and fairs; plus, we have a crew of Canvassers who go door to door in priority neighborhoods. We strive to reach historically under-served, low-canopy neighborhoods with information about how to volunteer with us and how to get a tree from us. Interested in being a part of this? We’d love for you to join us.
This Saturday, April 13th, Friends of Trees volunteers will plant more than 1,000 trees and native shrubs in Tualatin with longtime partners Portland General Electric (PGE) and the City of Tualatin. PGE employees, including Maria Pope, PGE’s President and CEO, and their friends and family will be planting alongside representatives from the City of Tualatin and its Mayor Frank Bubenik, and community members.
This year, PGE announced a special gift of $100,000 that will help Friends of Trees reach the milestone of one million trees planted since its inception. PGE has supported Friends of Trees since its founding in 1989; PGE is sponsoring a total of 10 planting and tree-care events, bringing the total of PGE-sponsored plantings to more than 100 since 2005.
Some of the Why, Where, and What-Have-You of planting trees in the city with Friends of Trees
Since 1989 Friends of Trees has been growing our urban canopy through planting street and yard trees in neighborhoods. A LOT changes during 30 years of tree planting! We continually work with our city and county partners to ensure the right tree is planted in the right place, and since every location is different we are used to getting quite a few questions. Here are answers to some of the questions we get the most:
I want a smaller/larger tree for my planting strip but all the trees on this list are just too big/small, why can’t I get a smaller/larger street tree?
We work closely with our municipal partners and we can only plant trees that are on their approved street tree planting lists. One of the goals of our program, and the partners we work with, is to increase the urban canopy in order to maximize the benefits. In other words, the larger the tree, the more the urban canopy grows, which provides more benefits in terms of cooling in the heat of summer, providing oxygen, and cleaning our air and water. So when a planting site allows it we need to optimize the size of the tree planted, and consequently, maximize the benefits provided. We also want to make sure we aren’t planting trees that are too big, in order to protect existing urban infrastructure. So these same guidelines ensure we aren’t planting over-sized trees in spaces that are too small.
I want to plant a fruit tree in my planting strip and I know you have them, why aren’t they on my list of approved street trees?
Fruit trees are only approved for certain spaces, such as yards or planting strips that are six feet or larger and have overhead primary power lines (however, Vancouver and Clark County do not allow fruit trees to be planted as street trees at all). If you’d like a fruit tree for your yard in addition to your street tree, we offer a wide variety, including apple, pear, plum, fig, and persimmon.
I only want native trees for my street tree and you only have one native on this list, why don’t you plant more natives?
Right Tree Right Place! We love native trees, but many tend to get pretty big and just won’t work in some planting locations due to overhead power lines, if the strip isn’t wide enough, a nearby intersection, etc. We want to make sure your tree is the best tree for your planting spot! We also want to plant as diversely as possible toward a resilient urban forest. P.S. Want to plant some natives? Join one of our Green Space planting events–all natives, all the time.
I want a street tree, but will it break the sidewalk?
Again, Right Tree Right Place! The trees offered by Friends of Trees do not have aggressive root systems and are specially approved to minimize such conflicts. Proper watering also helps. Deep watering for the first three years after planting encourages tree roots to grow deeper in the soil, we recommend 15 gallons a week during the summer for the tree’s first three years, and as needed in the future when temperatures are extreme. Keep in mind that we cannot guarantee that the trees we offer will never buckle sidewalks, as they are living beings and situations vary. We do our best and encourage you to keep an eye on your tree.
I’m concerned that tree roots will damage the sewer pipe, doesn’t this happen?
A tree’s roots grow where the growing is easy, they are opportunistic and not invasive. They do not seek out water or sewer pipes unless the pipes are leaking. Further, 90% of tree roots are in the top 2-3 feet of soil, and most sewer lines are deeper than that. Your municipal tree inspectors take into account the location of your water meter and assigns the planting location within the guidelines of the water company.
Can you help me remove a tree so I can plant a new one with you?
We can’t help you with a tree removal, but you can re-plant with our program if the city allows you to remove your tree. If you want to remove trees in your yard, check with the city to see if there are laws affecting your tree. To remove a street tree, you need a permit. Contact your city’s urban forestry department directly for a removal inspection, a list of contact information for our municipal partners is here. It’s a good idea to request that the city mark “all approved locations.” If you want to re-plant with us after removal please include on your application that you are working with Friends of Trees. Visit our website for more information about tree removal and replacement.
The approved locations where the trees are going are strange, can you change the location?
Unfortunately we can’t change the location. All street tree locations are based on a city inspection, and there are many factors involved, including distance from underground utilities, overhead lights and power lines, utility poles, fire hydrants, intersections, and street signs. Planting in the spot chosen by the inspector will help ensure your street tree has the best shot at surviving–and thriving!
