Congratulations to Aaron Byer for passing the rigorous International Society of Arboriculture certified arborist exam. He joins 3 other full-time certified arborists on staff at New Urban Forestry. Aaron started professionally climbing trees in 2011 and has previously worked for companies all over the Southeast, including Davey Tree in Greensboro, North Carolina. He has been with New Urban Forestry for just over one year. He is currently a sales arborist, so make sure to congratulate him when he comes to look at your trees.
As the cooler fall weather moves in and changes our landscapes from summer green to shades of yellow, gold, and orange; you may begin to see one persistent pest that refuses to give up the green. In fact, it refuses to give up at all. Under the cloak of your trees’ leaves, mistletoe has found itself a home. Whether it be on the humble Hackberry or your prized Texas Red Oak, it has been growing—pulling its moisture from the host.
One of nature’s most harmful “bird gifts”, mistletoe seeds, move from one landscape to another looking for that perfect arboreal environment. The two and three year old wood on Cedar Elms and Hackberry trees are prime real estate, but a few other local species will do in a pinch. Once the location is right, the seed germinates and a strange, opportunistic root-like structure finds an opening in the bark and taps in to the tree’s vascular system. Mistletoe becomes a tree squatter, ready to take the neighborhood.
Urban Soils and Tree Root Issues
A couple of years ago, during a notably large storm, a prodigious water oak fell on my neighbors’ house. This beautiful old tree could not support the weight of the branches because the root system had been compromised from years of cars rolling, parking and compacting the soil surrounding the base. Fortunately, in this case, the family was not in the house and only the house and tree were compromised, but it offers valuable insight into the damage that human activity can cause the trees in our community.
The dirt around us is constantly changing. Wind and heat and gravity and water all affect our soils. These are important positive components in creating an environment for many ecosystems. In an urban environment, one additional component is changing the soil around us: people.
People have a huge impact on the urban soils. Enormous cavities are dug for underground parking decks, the Georgia red clay is hauled away and piled to be used somewhere else, it is added to other tracts for other projects. The soil is leveled and graded and compacted. It is walked on and parked on, played baseball on and picknicked upon. Human activity is one of the main contributing factor in the changing urban soils.
This changing soilscape directly impacts the growing trees around us. Without careful consideration to how we impact the soils, human activity can have serious negative effects on our canopy.
One negative impact is the creation of a surface crust. This is caused by removal of the natural vegetation combined with compaction caused by foot traffic or wheels, and fine particles filtering in and filling in gaps beneath the surface. This hard crust doesn’t allow water to seep into the ground and be absorbed by the tree roots.
Water drainage and insufficient aeration can have a negative impact on the absorption capabilities of the trees. If the soil is too fine, such as with clay soils, it can become water-logged which can be equally bad for the root system.
When a new home is built, the ground must first be leveled. During this process, the topsoil is removed and often fill material is brought in from somewhere else. This can create layers in the soil that are different from the natural makeup of the land. This can be damaging to existing trees and can cause problems when planting replacements. The change in soil composition, including the ph and chemical makeup as well as density of the soil can prevent trees from receiving the nutrients they need to thrive.
There are several ways to remediate these effects on our trees. The first is to be aware of abused areas of your own landscape. Pay attention to where you park, where your children play, or areas that see more foot traffic. Try to park in areas that are far away from trees or only on existing parking pads. Divert traffic away from natural areas or create trails that have proper erosion control.
If you notice that the roots have been damaged in your landscape, there are plant healthcare guidelines that can prolong the life of your trees and repair damaged soilscapes. Contact a certified arborist to help with your tree concerns and you can hopefully prevent your trees from falling during the summer storms.
How do we love our trees? Aside from just giving them a big hug from time to time? There are things you can do to show your tree love that will sustain its life, beyond just regular pruning and maintenance.
We all know that trees need water. But how much water and when? I can’t tell you that. But an arborist looking at your trees can. Are they drought tolerant species? Was it planted in the last 2 years? What is the soil like surrounding the tree? Getting the right amount of water (and seriously, not too much) is one of the first ways to make sure your trees know you care.
Speaking of soil…
What does an arborist know about soil? Don’t forget that tree roots extend far below the surface. Trees start from the ground up. To hug the entire tree, you have to get your hands dirty.
One of the biggest dangers to our trees is soil compaction. Do you park your car under the tree? Do your kids play under a particular tree every day? This compaction can damage the roots of the tree. Your tree may look fine now, but compacted soil can eventually lead to insect infestation or stress which can lead to vulnerability months or years down the road. Improving the soil surrounding trees can rejuvenate ailing trees and prolong the life of your investment.
One soil-improvement method that might be recommended by an arborist is radial trenching. This is the fancy way of saying: digging holes (in a radius) and filling them with nutrient-dense soil. This calculated process is designed to aerate and supply nutrients and prolong the life of the tree.
Do you spray pesticides on your tomato patch? Did you fertilize your turfgrass? Your whole landscape can affect the trees in and around it. They all share the common soil. This is one reason why an arborist should help when planning what to plant and where. We can help plan when treatments are appropriate and will not be harmful to your trees and shrubs, and also how pruning and treatment of trees can affect the other plants as well.
Planning your landscape with the longevity of trees and plants in mind with the help of an arborist can prevent problems that might occur years down the road and show your trees that you love them for many years.
New Urban Forestry is excited to offer a customer referral program. We recognize that our success is based on your support. We would like to give back to those who have shared their positive experiences with their friends and neighbors about our services over the years. As a benefit to you, your friends, your neighbors, and the broader Athens community, we would like to offer a gift to show our gratitude.
We are aware that often you receive little in return when a tree is removed. We believe in the future of trees in Athens. We hope as a business to not only maintain the existing tree canopy in our community, but also prepare for the future tree canopy. For every tree that we remove, we hope that an additional tree is being planted to replace it. We’d like to help in this process by giving our customers a tree to plant.
How it works
If an existing New Urban Forestry successfully refers a new customer, New Urban Forestry will give the existing customer a thank you gift. Please let us know if someone has referred you.
What is a Successful Referral?
A successful referral is when a new customer mentions an existing customer by name and both customers have had work completed by New Urban Forestry.
What is the gift?
New Urban Forestry will donate to the referring customer one 3 gallon tree that is drought and disease resistant and appropriate for our region. If you do not have room for a tree, or do not need a tree, we will give you a t-shirt designed specifically for our customers. For each t-shirt we give away or sell we will donate $5.00 to the Athens Clarke County Community Tree Council to assist with area-wide tree plantings.
Thank you for your business and your support!
The Lyndon House Willow Oak is set to be removed at the end of the month.
The Athens Clarke County Community Tree Council is responsible for, among other things, designating Landmark and Champion trees throughout the county. (landmark trees from tree ordinance):
Criteria for designation. Landmark trees shall be healthy trees that meet one or more of the following criteria:
- Age greater than 50 years as determined by planting records or the written opinion of an arborist, the Athens-Clarke County Arborist, or the community forester.
- Large canopy trees greater than 36 inches dbh, medium canopy trees greater than 24 inches dbh, and small canopy trees greater than 12 inches dbh.
- National, state, or Athens-Clarke County champion trees.
- Unique or rare species.
- Association with a documented historic event, person, or community landmark.
- Trees planted for Arbor Day celebrations and other community-wide public celebrations.
- Trees planted in honor or memory of an individual or an event.
- Trees belonging to a significant cross-property or neighborhood-wide planting that affect the greater landscape beyond the property on which they grow.
One notable Landmark and Champion tree is the majestic Willow Oak that stands in front of the Lyndon House on the edge of downtown Athens. This tree, honored with champion tree status in 1999 at the ribbon cutting of the Lyndon House arts center is being removed at the end of this month. Didi Dunphy, program supervisor at the Lyndon House and Roger Cauthen, Landscape Management Division Administrator for Athens Clarke County recently discussed the decision to remove the tree as well as some of the plans for the wood and the campus of the Arts Center.
Determining the exact age of the tree has proven to be rather difficult. There is speculation that the tree dates back to the 1850’s. Didi and Roger help explain:
“My look into it for photographic evidence only went back to the 70’s, where I could distinguish that tree in a landscape, and that was at the beginning of the arts facility being in our historic house museum. However, there has been discussions that it could be as old or potentially as close to as old as the house, but we really won’t know until it has fallen and with the hopes that the rings will be distinguishable,” said Didi
Roger elaborates, “As long as I have been witnessing the tree, since 1980, it’s been in a similar size and form with the fluted trunk. So when I first began to observe the tree and be a part of the local government, it was regarded even then as a significant tree.”
The decision to remove the tree was not altogether unexpected.
“I’ve been in place as the supervisor for a year and a half now. At the time, Roger came over, very early on and told me that several arborists had been looking at it and that it looked like it was entering the end of its life cycle and I had thought maybe 3 years, but it’s accelerated. And it’s based on a number of dead, large dead branches, that for me as a facility with a lot of people and youth has become hazardous period,” Didi said.
Mitigation efforts had been made for many years to preserve the life of the tree.
“It’s been mulched with organic mulch for a very long time now. It has a lightning rod system that has been maintained and restored every several years for quite some time. It has over 20 support cables in the scaffold limbs of the tree to reduce the risk that limbs would break away and fall out and disfigure the tree – that are all a part of its whole integrity now,” Roger said.
Being an arts center, there are naturally plans to honor the tree through art as well as use some of the wood, if salvageable. Oneta Woodworks has also agreed to partner with the county to dry, store,and mill the wood.
“My goal is to try to make the sadness a little less. But it will be a tremendous loss because that is a majestic tree,” said Didi.
There are plans to use pictures painted by children inspired by Klimt along with historic paintings of the tree and photographs taken throughout the years to create a 2d exhibit in honor of the tree. Depending on the condition of the heart and interior of the tree, wood sections could be used to create a bench for Sandy Creek Nature Center and outdoor seating at the Lyndon House which the UGA Landscape Architect Department will help design. Burls may be used by a local woodturners group that meets at the arts center.
As far as replacing the tree, Roger has been counting acorns dropped by the oak in hopes that at least one will grow into a sapling. However, bugs,
rain, and squirrels did not leave many to choose from.
“Roger has promised me a bank of trees along the edge of that part of the campus to give it a buffering,” said Didi.
Roger added, “that tree has been so dominant in its presence and character over the years that it’s impossible to replace that architecture there. But at least in the interim period perhaps while we get a seedling going, we would like to have a tree presence along that edge.”
If you are interested in using wood for an arts project and possible art exhibition, please contact Didi Dunphy at firstname.lastname@example.org
- It is known as City Cemetery and was sold in 1897 during the Spanish-American War to the government to create a training base for soldiers. They built an army hospital on the site.
- In 1898 the government sold the land back to Athens, which then dubbed the hospital “The Pest House.” It was a TB hospital.
- Part of the hospital was moved in 1914.
- All that is left are 30 graves, most near-identical with square, concrete headstones. Some of the graves may have been covered up by the H.T. Edwards building.
- The cemetery has also been known at times as Pauper Ground or Poor Burying Ground according to some death certificates.
When I was in college at UGA one of my favorite things about living in Athens was driving into town late at night after Thanksgiving break, the end of a long drive back from visiting my parents in Virginia . Every year, I would drive down Clayton Street first thing, even if it wasn’t on my way, and I marveled at the sparkling lights in the trees, newly lit for the holidays. It was beautiful. And it reminded me of why I chose to live in Athens, so far away from my family.
Trees provide such a sense of place. My final year of college, I lived on the cobblestone portion of Finley Street, home to another famous Athens tree.
Would Athens even be on the map if it weren’t for the Tree that Owns Itself? (of course) That particular tree doesn’t just put Athens on the map for something other than music, but it also represents the spirit of the town.
When you plant trees, you might not be thinking about who will decorate them with lights in the future, or even if you want to leave your money to it when you die, but you are creating a history of the land and defining a sense of place for future generations to recognize as home.
As the climate talks in Paris come to a close, it’s hard to ignore the chatter about greenhouse gases, carbon footprints and emission levels. One method that some people are using to combat the rising level of greenhouse gases is through carbon offsetting through tree planting.
On a large scale, companies pay to have others, often non-profits, plant trees on their behalf in order to offset their emissions. According to an article in The Guardian, “Carbon offset schemes allow individuals and companies to invest in environmental projects around the world in order to balance out their own carbon footprints.”
But this leads to questions on an individual level — will planting trees in my backyard really have an effect? Or, how many trees do I really need to plant? Can I do my own carbon offsetting?
There are several calculators available like this one or this one which will calculate offset for you. So for example, if you drive a gas car that gets 26 mpg and on average 12,000 miles per year, this calculator recommends you plant 9 trees to offset the emissions from your car. This puts into perspective real tangible ways to help the environment. I can plant 9 trees. That seems feasible.
New Urban Forestry is not a carbon offsetting program, and we can’t tell you exactly how many trees you personally should plant. We CAN however help you to plant your trees. We can offer advice on the care of your trees and also which trees are sustainable in the Athens and surrounding areas.
New Urban Forestry often is called on to remove trees due to safety concerns; we are charged with removing a valuable resource from our local community. We want to be able to replant those trees.
Together we can continue to give Athens a unique sense of place, and also create a more sustainable world for our future.
Manage Effects of Moth Infestation
The Athens-Clarke County Unified Government’s Environmental Coordinator is urging citizens to look for signs of the black-dotted brown moth (Cissusa spadix). Athens has experienced significant infestations of this pest for the past four years. In recent years, the outbreak has expanded to include Athens-Clarke, Jackson, Madison, Oglethorpe, and Oconee County. The outbreak is expected to be more widespread this year, however, with less damage and defoliation to the individual trees. Learn how to manage effects of moth infestation.
The caterpillar tends to feed on tree species from the white oak group, with a special preference for post oaks (Quercus stellata). High densities of the caterpillar will completely defoliate these trees. Repeated defoliations can lead to crown dieback, tree decline, and risk for early death.
Typically, owners do not notice infestation until the tree experiences rapid and nearly complete defoliation. Other signs of an infestation include unusual loss of bark plates due to predators feeding on the inchworm-like caterpillars underneath that secrete a reddish brown liquid when disturbed and large amounts of frass (insect excrement) accumulated beneath the trees.
Dr. Kamal Gandhi, a forest entomologist at the University of Georgia, has already begun to see signs of emergence. Control methods should be taken immediately. If this is the first year property owners have noticed the insects, it is recommend that they either closely observe the infestation without taking preventative action, take low impact actions to increase natural predation of the caterpillars, or prevent them from climbing the tree.
John Ritzler of New Urban Forestry in Athens, GA, suggests encouraging habitat for natural predators that feed on the caterpillars such as birds and squirrels to reduce the number of insects; providing bird feeders near white oaks can increase the presence of these natural predators.
Other methods of low impact control include the use bug barriers to trap the caterpillars in the lower trunk so they are unable to feed on the leaves of the trees. While many barriers are commercially available, several local residents have established that a 4-6” wide band of vegetable shortening around the trunk provides an effective, low cost method of exclusion. More information on the management of this pest can be found at the Environmental Coordinator’s website at http://www.athensclarkecounty.com/green.
Smaller oaks that have experienced defoliation for a number of years can be treated with a bacterial insecticide called Bacillus thuringiensis (Bt). Specimen trees that have experienced three or more years of defoliation can be treated with the insecticide Imidacloprid (sold as Bayer Tree and Shrub Insect Control, Dominion, or Merit). Use this treatment with caution and only on specimen trees and trees at risk for death. Many insects, including natural predators, can be affected by this treatment.
Prevention and treatment is the key to reducing the impacts of the black-dotted brown moth. Simple, inexpensive measures can insure that these pests do not defoliate and stress trees. Since this is a naturally occurring pest, many forest health professionals believe the intensity and frequency of the damage will subside as populations naturally decline due to harsh winter conditions, an increase in predation, and/or the spread of a disease that kills the caterpillars.
