On Line With Safety

2 A Letter from the President Dear MAA Members: Much has happened since the last issue of Shady Notes. First, I would like to thank all who took the time to respond to the many e-mail requests for feedback that have been sent recently. I receive each and every response, and personally delivered your thoughts and opinions to Annapolis. Speaking of Annapolis, Bob Mead, Frank Dudek, and I recently attended the signing of a bill sponsored by Delegate Pam Beidle (see picture right). This law will reduce the time a trainee must work under a Licensed Tree Expert from five years to three years before becoming eligible to sit for the LTE exam in Maryland. The law will also, beginning in 2015, require current LTEs to obtain professional development as a term of recertification every two years. The Maryland Department of Natural Resources also supported this endeavor and will be working closely with the MAA to develop the regulations for this law moving forward. A special thanks to Matt Anacker, Tom Mayer, Jeremy Baker, and everyone else who arranged and participated in the recent Arborist Day event at Patterson Park. This volunteer service day was a huge success. (See page 6 for pictures and a summary of the event). The following is a blurb from a Matt Anacker e-mail following the event: (On Saturday, April 13, 2013, The Maryland Arborist Association, Inc. had fifty-five (55) volunteers prune approximately (90 +/-) 18” average diameter landscape trees for the Friends of Patterson Park, Inc. in Baltimore City - on a fantastic day - !! The volunteer arborists also removed six (6) dead trees and the resulting stumps were ground below grade. A big thank you to our sponsors: Gambrills Equipment, Inc., Georgetown Insurance, Inc., Vermeer, Altec, IWIF, Rainbow Treecare Scientific, and Slater Associates, Inc. And a big “thank you” to all of our volunteers!) Furthermore, I am saddened to report that Tom Mayer has resigned his post as MAA Membership Committee Chair. Tom has been a member of the MAA for over twenty-five years and has offered to continue to assist the organization in the future, as his schedule permits. Thanks to Tom for his years of service to the organization! In closing, I would like to welcome Mr. Rob Muir as our new Safety Committee Chairperson and Mr. Bob Stanley as new Membership Committee Chairperson. They both answered our request for interest in these open committee positions. We are very happy that they will be joining us and bringing their experience to the board. I wish everyone a safe and prosperous summer! Best, John Davis

Safety Feature – Tick Bite Prevention and Treatment Summer is here again and so are the ticks. Lyme disease is the most common tick-borne disease in Maryland and is transmitted by the bite of an infected black-legged tick (sometimes called a deer tick). Since 2000 there have been 15,883 reported cases of Lyme disease in Maryland and this year is predicted to be a very active tick season.

Tick Bite Prevention There are several things that can be done to help prevent tick bites. • Check animals before they come in the house for ticks. • Wear long pants and long sleeves. • Tuck shirts into pants and pants into socks to help keep ticks on the outside. • Wear light colored clothing to help spot ticks that have hitched a ride. • Ticks are extremely sensitive to dryness – so when you are done working outside, put your clothes in the dryer for 10-15 minutes on high – BEFORE you wash them. This will kill any ticks on your clothes. • When applying tick repellant don’t forget your shoes. Ticks attach by crawling – through leaf litter and debris which we walk through. This is one of the most effective ways of preventing ticks from gaining access to you. • Don’t just spray the outside of your clothing, but spray the inside of pants (bottom 8-10 inches) and shorts. Ticks crawl up your clothing – both on the outside and inside of your clothes – so treat both sides. Repellants like Permethrin must contact the tick in order to be effective. • Do DAILY tick checks. • Duct tape can be used to “de-tick” as soon as you notice ticks are crawling on your clothes. This is a very easy way


to remove ticks. Once they have latched on you, you may need fine pointed tweezers for removal. You have done everything noted above and a tick still got through and bit you. What do you do now? Safe Removal of Ticks Remove the tick from your skin as soon as you notice it. Using fine tipped tweezers, grasp the tick very close to your skin, and with a steady motion pull the tick’s body away from your skin. Clean your skin with soap and water. Mark your calendar noting the tick removal. Avoid crushing the tick’s body. If you crush the tick, clean the skin with soap and warm water or alcohol. Don’t be alarmed if the tick’s mouthparts remain in the skin. Once the mouthparts are removed from the rest of the tick they can no longer transmit Lyme disease. If you start to feel ill (achy joints, flu-like symptoms, tired), and notice a “bull’s eye” looking rash where you were bitten, days or weeks after removing the tick, make an appointment to get checked out by your doctor. Lyme disease is treatable with antibiotics. Treatment is easier the sooner it is diagnosed. In the end, with a little planning and preventative measures, tick bites can be avoided and we can all get back to enjoying the long summer days.

A Letter of Thanks



Maryland Arborist Day ❦ April 13, 2013 Thank you to all of our members and affiliates who came out to support a wonderful cause! We had fifteen MAA member companies send in excess of fifty volunteers. Before it was a park, the site of Patterson Park played a major role in the War of 1812, serving as the grounds where American troops stood ready during the decisive battle of North Point at “Hampstead Hill.” This area of the park now is where the Pagoda is situated. After all of the wonderful work that our volunteers have created, the park can once again serve as a beautiful recreation site for neighborhood schools and churches. Maryland Arborist Day is an enriching event held each year, and we can’t wait to see what 2014 has in store for us!

Press Release Passage of State’s budget during special session advances conversion of IWIF to Chesapeake Employers’ Insurance Company “Business as usual for policyholders and agents,” says IWIF’s President (TOWSON, Md.) — Maryland’s General Assembly has passed, and Governor Martin O’Malley has signed into law legislation that will convert IWIF, the Injured Workers’ Insurance Fund, to Chesapeake Employers’ Insurance Company (Chesapeake), effective October 1, 2013. Chesapeake will be a non-profit Maryland corporation and will continue to provide workers’ compensation insurance to Maryland employers. IWIF is Maryland’s largest writer of workers’ compensation insurance. Thomas Phelan, President of IWIF, welcomed the legislation’s passage. “This action will position us for continued success in serving the workers’ compensation insurance needs of Maryland employers,” he noted. “The legislation will protect IWIF’s surplus and will allow us to remain financially strong. In addition, there will be no change for our policyholders and the insurance agents with whom we partner. For them, it will be business as usual.” IWIF markets workers’ compensation insurance through independent agents and directly to business owners. IWIF’s current assets total $1.7 billion. The legislation, approved by the General Assembly, establishes Chesapeake Employers’ Insurance Company as a private, non-profit workers’ compensation insurer with the same mandate to serve Maryland employers only. IWIF’s existing nine-member Board of Directors will become the directors of Chesapeake Employers’ Insurance Company. The Governor of Maryland will continue to make appointments to Chesapeake’s Board. Under the legislation, the State will no longer have any claim to IWIF’s surplus. Over the prior legislative sessions, the State has introduced legislation to transfer funds from

IWIF’s surplus to the State’s general fund. The Governor passed the bill authorizing a $50 million transfer and authorized a study to determine if additional value is warranted. This value is determined by considering any financial contribution made by the State to IWIF and any financial benefit received by IWIF from the State. “Protecting and stewarding our surplus for the exclusive benefit of our policyholders is an important priority accomplished with the passage of this legislation,” Phelan noted. “Otherwise, our surplus would remain vulnerable to future transfers by the State, rather than be available for their original purpose, which is financial stability to ensure payment of injured worker claims. I am confident IWIF will remain financially strong and will continue to provide exceptional service and rates.” Another change resulting from the legislation involves the status of IWIF’s employees. Current IWIF employees will have the right to continue as State employees and participate in the State’s retirement system, or they can opt to become employees of the new company and participate in its separate benefits plan. All employees hired on or after October 1, 2013, however, will be employees of Chesapeake Employers’ Insurance Company, not the State of Maryland. Created by the State in 1914 as the Maryland State Accident Fund, IWIF has operated solely from premium and investment income. No taxpayer dollars support IWIF. From its beginning, IWIF has operated as a guaranteed market insurer providing workers’ compensation insurance to all who apply, regardless of a company’s size or past claims experience. With its obligation to insure all comers, IWIF performs an important role in supporting new business creation in Maryland. Under the legislation, Chesapeake will continue its mission as Maryland’s leading provider of workers’ compensation insurance.

Tree Benefits Calculator The Maryland Department of Natural Resources sponsors a program called “Marylanders Plant Trees. This program offers consumers a coupon towards the purchase of a new tree. A really exciting tool unveiled with the launch of this program is a “tree benefit calculator,” which consumers or industry folk can use to quantify the benefits of planting a tree. Landscape contractors, arborists, and retailers, especially may want to be aware of this calculator, to

further educate your customers on the benefits of trees. The calculator provides data on storm water runoff intercepted by a tree, impact of the tree on property value, energy conserved by the presence of the tree, contribution of the tree to air quality, and effect of the tree on the reduction of atmospheric carbon. To access the calculator, go to www.treebenefits.com, which is a separate page found within the Marylander’s Plant Trees website.

Hard Decision Coming Up with Ash Trees Protect it or cut it down? This is the decision that managers are going to be faced with over the next couple of years if there are green or white ash trees planted in the landscape. Green and white ash were one of the top selling nursery trees for over forty years and lots of them were installed in new communities around office parks throughout the metro area. Many of these trees are now big caliber trees of 15 – 25” DBH. You heard the saying “The bigger they are the harder they fall.” This will be very true in many landscapes. In May of 2013, a meeting was organized to help city managers and arborists understand what we can expect as emerald ash borer continues to establish itself in Maryland. We have brought in urban forester managers from midwest cities that had to deal with the fall of the ash in the mid-west. They comment that you go through about three or four years of discovery of the pest in the area followed by a tidal wave of dying trees. This is called the “Exponential Death of Trees”. You really need to start planning in these early stages because when the “Exponential Death of Trees” starts you will have a large number of dead trees that have to be taken down. If you can keep your ash tree alive through the tidal wave, then the population goes down and you are hopefully left with standing trees. The question is, how much are you are willing to spend on protecting the ash and for how long? There is no natural resistant to the emerald ash borer among ash trees, so the choice is which chemical do you treat the tree with to protect its life. You also have to decide when the tree should be taken down. Sounds simple enough, but as many things in life, it is not simple at all. A big tree not only shades areas reducing temperatures in summer, it also absorbs huge amounts of runoff water. Taking down a large tree is going to dramatically change the environment in the area where it was growing. It is also expensive to remove a tree and its stump, and then grind out the roots. A replacement tree takes years to grow in. So inject and save the ash or cut it down? I lean toward removing the tree and starting over with another species of tree, but it can be argued it is best to inject and save a tree a little while longer until the tidal wave passes by. The other thing is it may be too expensive to take down all of the ash trees in an area preemptively. Some city foresters are choosing to go out and rate the quality of the ash tree and evaluate its potential hazard if it dies. They rate the trees on a scale of say 1 – 5 with 5 being the trees that should have priority on being removed. One

city in Maryland that has 22,000 ash trees in its tree inventory is choosing to remove 500 ash trees each year, picking the ones with a “5 ‘rating. They are injecting 25 -30% of the better ash trees to give them more breathing room before these trees have to be removed. Eventually the plan is to replace the ash trees with other species of trees and try to have a mixed species of trees to protect against outbreaks of other insects coming in the future. This is probably the best long range way of dealing with EAB. The adult beetle will out in May. The adults of emerald ash borer emerge at 450 degree days about the time that black locust are in full bloom. If you are taking action with insecticide treatments then May and June is the best time to apply treatments. Here is a list, Table 1, of chemicals with time of application and how long they will give control of the emerald ash borer: Table 1. Insecticide options for professionals and homeowners for controlling EAB that have been tested in multiple university trials. Some products may not be labeled for use in all states. Some of the listed products failed to protect ash trees when they were applied at labeled rates. Inclusion of a product in this table does not imply that it is endorsed by the authors or has been consistently effective for EAB control. This chart, Table 2, is adapted from the publication “Insecticide options for Protecting Ash trees from Emerald Ash Borer” at www.emeraldashborer.info/files/multistate_eab_ insecticide_fact_sheet.pdf Table 2, This is a chart to help you understand how long each of the soil drench or injection, bark spray or injection will provide control of EAB and approximately what professionals are charging to treat trees per each inch of DBH (diameter at breast height). This is not the actual cost of the chemical but is the range of what most certified pesticide applicators are charging to make an application to a tree. In Canada they have severely restricted the chemicals that can be used for insect control. The Canadian Forest Service has backed the development of a 5% Azadirachtin B marketed by BioForest Technology, Inc (Distributed in the US by Rainbow TreeCare) for tree injection that should satisfy the organic type customer. The product is called TreeAzin systemic insecticide. This is an organic systemic insecticide (OMRI listed) for control of Emerald Ash borers. The Azadirachtin that is extracted from Neem tree seeds acts as

17 an Insect Growth Regulator. The larvae are prevented from completing development and die before they can go to the next instar (growth) stage. When treating with TreeAzin for control of EAB it is suggested to use between 5 to 18.5 ml per DBH. It has been tested in Canada and is supposedly providing 95% control of EAB larvae. It is being tested in United State sites in 2013.

The product must be stored at 40 – 70 degrees Fahrenheit and will last 1 year in storage. When you take it out to the field it is recommended that you pack the material in a cooler with ice packs to keep it cool. The formulation is very thick and it is injected using large tubes and takes 30 -60 minutes to get it into the trees. (continued on page 18)

18 (continued from page 17) Back to What to Do In May of 2013 the city Forester from Fort Wayne, Indiana was asked to come and address arborist and landscape managers on how they dealt with EAB in their city. Chad Tickle, the city forester, started with the comment “As the population of EAB goes up, the options goes down.” His approach is to remove a certain number of ash trees each year and treat a set number of trees to buy time until you have to take the trees down. There just isn’t enough money to take the entire ash tree down in most cities on one year’s budget. He mentioned that is the early stages that we are in most of Maryland you can get lulled into thinking you don’t need to do anything. This is a bad decision because in 2-3 years you are suddenly faced with many standing dead ash trees. During the meeting Nevin Dawson, forestry expert, of the University of Maryland Extension commented that the City of Baltimore has over 300,000 ash trees in the city. This is one Maryland city that better start developing a plan for dealing with EAB and soon. In Fort Wayne, when Chad started in his job in 2008, there are 59,000 street trees in the city limits. In 2013 they have 46,000 trees in the city limits. The reduction in tree numbers is mainly removal of ash trees. They still have ash standing but not many. Green and white ash was 25% of the Fort Wayne city tree plantings back in 2008. They started their management program with a tree inventory, to know what they have and where the tree is located. They

then evaluated the tree health and determined which trees needed to be removed immediately and which trees could be treated with Imidacloprid to give them 1 year of control and at least 2 more years until the tree would be killed by EAB leading to the need for removal. It is a buying time strategy. Originally in Fort Wayne they treated 11,000 trees with spoil injection of Imidacloprid to buy time. Now they treat 1300 trees per year. Chad also noted that emerald ash borer seem to like green ash the most with white ash being less preferred, but it still will be attacked. Chad told the group that the 14,000 trees in Fort Wayne have cost $7.2 million to take down and treat from 2008 – 2013. Even with this aggressive plan it is not enough for many people and Chad still receives in over 250 complaints about dead or dying trees in the city from citizens who want immediate action to remove the dead trees in their neighborhood. He said you better be organized and prepared. This is good advice for us here in Maryland. We are not trying to scare anyone with this article but you need to make sure your clientele understand the choices and the consequences of “no action.” Hope this short summary is helpful.

21 An Oasis of Green in McElderry Park Submitted/Reprinted with permission from Bartlett Tree Experts “Hi, what do you do?” “I’m an arborist that takes care of trees in Baltimore City.” “Baltimore . . . have you ever seen The Wire?” I can’t count how many times I’ve had conversations that start out like this one. Whether it is at a family get together, casual dinner, party, or just friendly conversations with the person sitting next to me on the plane. It seems that Hollywood, like in most of its depictions, has misrepresented the city of Baltimore. Baltimore is a city made up of hundreds of little communities and yes we have trees in Baltimore. But we need more! We have one of the largest geographical areas of park land within city limits, but our urban forest is aging and our canopy coverage is dwindling. We have a few organizations that are looking to change that by bolstering the current tree canopy of 27% to 40% by 2040. In order to accomplish this it is estimated that 25,000 trees a year will have to be planted by the city and its residents. Baltimore Tree Trust (BTT), a 501(C)3 nonprofit has partnered up with Tree Baltimore to do just that. Pulling from a large volunteer base, BTT has been getting the community involved in planting trees. They also help educate citizens and form stewardship programs in an effort to promote the sustainability of the city’s trees. Their current project is in a neighborhood known as McElderry Park. Located in East Baltimore between the world renowned Johns Hopkins Hospital and Canton, just a few blocks north of Patterson Park, is McElderry Park. To reference this neighborhood as a park is a little bit of a misnomer. Most of the streets are barren of trees and the pavement rolls up into the sidewalk that goes right into the houses. Baltimore Tree Trust saw this as a huge opportunity. They have started involving residents with their children to plant 800 new trees by the end of 2015. On the southern end of the community lies the Patterson Park Branch of the Enoch Pratt Free Public Library. On the grounds of the library and extending westward is a grove of mature linden trees. This is like an oasis of green in an otherwise concrete world. Being the only mature trees around

they are priceless to the community and Baltimore Tree Trust’s efforts to revitalize the neighborhood greenery. Working for Bartlett Tree Experts for the past fifteen years, I have had the honor of pruning and caring for many city residents’ trees. I have been helping Debbie Cameron take care of the community parks in Otterbein for the past few years. Being an advocate for the city and trees she found herself on the board of the Baltimore Tree Trust. She asked me if I could meet with Amanda Cunningham, the executive director of the BTT to look at some trees in a neighborhood they were working in. I was expecting to see a couple of trees that our team could help them out with. Needless to say I was a little floored when we walked up on 24 mature lindens that had not been pruned in… well I couldn’t even tell. Upon realizing that this was a little bigger than having the crew swing by at the end of the day, I got in touch with Peter Becker, our division manager of Bartlett Tree Experts. We were able to formulate a plan and set it up for an Arbor Day project. Unfortunately that was only a few weeks away. Amanda was able to work with the city that donated all the necessary permits and posted no parking work zones for the day of the project. Bartlett was able to donate three crews, trucks, and equipment. This “A team” lead by Tony Stockslager, Paul Mullins, and Jason Green worked all day to care for these trees. They removed dead and broken branches, thinned the canopies, and cleared the streetlights and city streets as well as fishing out some plastic bags that were creating an eyesore in the tops of the trees. During the project a local shop owner jumped in, getting people who had dismissed the city’s postings, to move their cars. It was great to see the residents of the neighborhood pull together and take pride in their trees. Now that the trees are safer and more light can pass through them, they plan to rework the park area to not only improve the aesthetics, but to also be a place where education and learning about trees can take place. All in all it was a great success. Baltimoreans are proud of their city, sports teams, and neighborhoods. Adding trees to that list just makes this arborist smile. Chad Vrany

On line with Safety Training and Education Update We made it through another spring â&#x20AC;&#x201C; cool, wet, and clients confused just the same. It is going to prove to be yet another strange year for pests and disease pressure. The MAA was hard at work in Annapolis this year, working with the legislature on some new bills. One bill, HB 572, has passed and will effectively reduce the number of years of experience required to sit for the LTE exam. Before, the passing of this legislature, the required number of years of experience was five years, and that has since been reduced to only three years. HB 572 will also require ALL LTEâ&#x20AC;&#x2122;s, effective in the 2015 license renewal year, to obtain continuing education credits along with valid insurance for effective license renewal. MAA is set and ready to go to provide all of the necessary training and education to meet this requirement. At this time MAA will be working with the team from DNR to set the guidelines for this training and education. There will be plenty of time to get the training needed and other training will cross-over once approved. This will make for a safer industry.
