Tree Testimony with Ahlum & Arbor Tree Preservation

Testimony Blog

Expert Testimony

Chris and Dave Ahlum represent two out of twelve board certified Master Arborists that offer expert witness testimony and consulting for litigation purposes in the state of Ohio. They hold the highest credentials in the industry: BCMA (Board Certified Master Arborist) and ASCA (American Society of Consulting Arborists). Additionally, as a matter of interest, Chris is the youngest arborist to receive both of these credentials and is on board of the Society of Commercial Arboriculture and the ISA Certification Board. Arborjet asked Chris to share about this interesting facet of their business, Ahlum & Arbor Tree Preservation.

The Usual Cases

“We regularly consult on cases where a developer trespasses and cuts down more than an acre. Often situations arise where a neighbor trespasses and cuts a tree down, then we consult on the value of the tree. Additionally, we receive calls from insurance companies to determine the cause of failure if a tree falls on a house.

“We were recently involved in a case where a tree fell from the woods across a two lane street, and sadly hit a car, severely injuring the driver. We were hired to determine if the tree was a hazard and if the owner should have been taking care of the tree.”

Traveling Testimony

“We are involved in 2-4 cases a month. My father stays in our local area but I am willing to travel out of state if the distance is reasonable. I have a case right now in West Virginia and I was recently involved in a case in Michigan.”

Arboriculture as a Lucrative Career Choice

“Often a career as an arborist is seen as a choice for teens that can’t make it academically. I try to inspire young adults so they see that you can make a career treating or climbing trees, or you can take the next step and make a very lucrative living consulting.”

Oak Wilt Invades San Antonio, TX

 

San Antonio TX

Oak Wilt is a fungal disease that attacks the vascular tissue of the tree, which can be fatal if left untreated. It has been in the United States for decades and has slowly made its way into the urban centers of San Antonio. There is no total prevention or cure for this disease, as it can be spread primarily through open wounds on the tree or more prevalently through root grafts.

 

Susceptible Oaks

Once the tree has been infected, the vascular system is no longer fully capable of supplying the needed water and nutrients for survival. A live oak can live for years in various states of health, a red oak tree generally succumbs to the disease within a few weeks. Generally, oaks in the white oak family such as burr oak and chinquapin oak are not susceptible to the disease.

 

The Disease Progresses

In San Antonio, there are numerous “pockets” of Oak Wilt, and many of the communities within the city are very proactive in their approach to the spread of the disease. Currently, the most devastated areas from Oak Wilt are within the Hill Country of Texas; however, more areas within the city of San Antonio continue to develop. Oak Wilt can also be brought into a community through infected firewood or tree pruning equipment. It generally travels approximately 100 feet per year through root grafts and may be accelerated during rainy periods. Trenching around the infected areas is often used to stop or slow the spread of the disease in conjunction with tree injections.

 

Treat Oak Wilt with Tree InjectionsAlamo

When treating for Oak Wilt with tree injections, it is often more cost-effective to treat the tree than incur the cost of removal. Oak Wilt will remain an issue in the city of San Antonio and its surroundings for years to come. Having an arsenal of tools to treat this disease will be beneficial for individual property owners and the community as a whole.

Trees with Oak Wilt can be treated with Alamo® Fungicide.

Today’s Update:

Starting off Strong

The final day’s decreased mileage (41 miles) was a welcome reprieve for the sore and tired participants. We rode out early morning and immediately faced a challenging climb up several hundred feet. Following the climb we found the roads to be leveled nicely and we made great time.

Fox Point

IMG_20140802_094521129(1)

At the 20 mile point, the group stopped in the beautiful town of Fox Point, where we dedicated a tree.

The State Fair

Wisonsin State Fair

The Wisconsin State Fair is a popular event that attracts almost a million visitors annually. This year, CBS TV News affiliate WDJT TV 58 covered Jeff Palmer’s stop at the state fair, along with Dick Rideout, WI DNR Forester. The story focused on the need to protect ash trees from Emerald Ash Borer, which currently has 20 southern Wisconsin counties under quarantine.

TDTday7(1)

Arborjet is donating ten years of TREE-äge® treatments to the DNR for trees on the State Fair grounds. The DNR hopes fairgoers will learn how they can save trees of their own. “Your tree is part of the urban forest, part of the community’s forest and you play a part in protecting the benefits that’s provided to the whole community,” Rideout said.

Tour des Trees raises $500,000 for The Tree Fund

IMG_20140802_124557742(1)We rode the final 20 miles to Mount Mary University as a group of near 100, arriving amidst cheers and a police escort. The Tree Fund accepted a check on behalf of all Tour participants for over $500,000!

Later that day, after warm showers were taken and fresh clothes donned, we broke bread with our Tour support team along the river in Milwaukee. We laughed and reminisced about our many moments across the miles. At the end of the day, most of us prepared for our next adventure, the ISA Convention starting on Sunday.

The Longest Ride

TDT_day7

The ride from Sturgeon Bay to Port Washington was the longest ride of the week at 120 miles. We enjoyed the scenery of rural landscapes of pastures of baled hay and wheat. We enjoyed a route close to beautiful Lake Michigan, where a breeze of the lake helped to keep us cool.

 

After the Storm

Later in the day, when the majority of the riders were in, a strong thunderstorm with hail passed through and pummeled those still riding. The storm quickly ended and the sun returned as the Best of the Tour awards ceremony and group dinner at Veterans Park in Port Washington began.

Kraak Day

 

IMG_20140731_192531_668
The day was officially pronounced Kraak day… as in Thom Kraak. Thom is a devoted tour support volunteer and entrepreneur who donated generously to tour riders today and throughout the week. Thom graciously hosted us for refreshments at his home on the route and organized a tremendous polka party with great food and camaraderie. We all truly appreciate the work Thom does for Tree Fund!

Jeffs Abound

 

IMG_20140731_202010_920
As a matter of interest, we have discovered that Jeff is a relatively common name and that odds are good that if you call a guy on this ride Jeff, he will turn around. At the polka picnic were able to assemble all of the Jeffs for a photo.

Tomorrow’s Challenge

We covered almost 60 miles today. Tomorrow we turn it around and head down the shores of Lake Michigan for the longest ride of the tour at 120 miles. Looking forward to the challenge!

The Tour Departs from Stevens Point

Wednesday was another century day on the bike as the Tour departed Stevens Point following a local tree dedication.  We rolled along, meandering through the big woods and back into the prairies and farm land approaching Green Bay.

We Break for Trains

IMG_20140730_152540_310

We discovered that only way to stop this dedicated bunch of riders is run a train in front of them.  The train in the picture stopped our group three times as we rode through Green Bay and gave us a chance to catch our breath.

 

 

 

 Dedication at Lambeau

IMG_20140730_174049_354

We enjoyed our evening at Lambeau Field after a touching tree dedication for a family who recently suffered a tragedy.  We made sure to give the new planting a fresh drink of water before we left as it is getting a bit dry around here.  Thursday’s ride is slightly shorter at 57 miles to Door County.  See you on the road!

Back in the Saddle with Jeff Palmer

IMG_20140729_070602_384

Tuesday provided riders with a much easier day in the saddle as the winds subsided a bit and the terrain eased. The road took us north from the Dells along the beautiful Wisconsin River.

Tangles and Treatment

IMG_20140729_073846_668(1)

Unfortunately, a couple of riders went down hard today when they tangled up with other bikes.  We hope they both recover quickly and are back on the road soon.  One of the riders was Bob Squibb of Western Tree Service, who is an avid Arborjet proponent and service provider in the San Diego area. I had a chance to talk with him the other night about all of the treatments he has been providing in the area protecting customer’s Oaks from Goldspotted Oak Borer. Feel better fast Bob!

Unlucky Trees

IMG_20140729_124747_541

We are riding in the area of Wisconsin that uses a lot of forest products and rode by a mill where I snapped a photo of a bunch of trees that didn’t make it.  Looks like they’ll be paper soon.  Looking forward to another good weather day on Wednesday as we coast into Green Bay and tour Lambeau Field.

Protecting and Connecting with Rob Gorden

Headed west from Massachusetts by car yesterday for the 1,100 mile ride to connect with the tour and Jeff tonight. Along route 90 we saw ever increasing signs of dead ash from the Emerald Ash Borer. We were pleased to know that towns in upstate NY including Syracuse, Rochester, and Amherst are protecting over 10,000 city trees with our products! Today we depart from Ohio, will pass through Chicago where they are protecting almost 80,000 ash with Arborjet’s support, and look forward to connecting with Jeff tonight as we are excited to complete the final 3 days of the tour.

Today’s Update:

On the Road Again

Last night we stayed at the Hyatt Place in Madison where I had a fantastic view of towering pines of the Wisconsin Dells. After a good night’s rest, we got back on the road and started the day’s 106 mile journey. I am a Stihl Tour des Trees rookie and have found that all veteran riders have been extremely helpful to me. This morning, Harry and Dick didn’t hesitate to stop riding when they saw me fumbling with a flat on the roadside.  With their assistance, I was rolling again quickly and we made it to the Arborjet demonstration on time.

Saving Ash Trees

photo(4)(1)The treatment demonstrations at Attridge Park in Baraboo were a great success. Arborjet donated injection treatments into 4 prominent ash trees in the park to prevent them from EAB infestation. The city has 1,200 publicly owned ash trees and plans to treat more than half in its urban forestry plan. This year, they’ve already treated 180 trees with Arborjet’s TREE-äge® Insecticide. Treating trees for Emerald Ash Borer before the infestation starts is a top priority in this quaint community.

Preserve and Protect

photo(1)(1)Baraboo Mayor Mike Palm praised Arborjet for helping city preserve and protect hundreds of ash trees through injection treatment. “These trees will continue to provide beauty to our park, shade to our residents and value to the community.”

Tomorrow’s Ride

Tomorrow we ride 87 miles to Stevens Point where I am looking forward to connecting with Dr. Rich Bauer, a great advocate for urban trees.

Today’s Update:

Kicking Off the Tour

Day 1 of the Tour seemed like homecoming for me as I spend a lot of time both in the Milwaukee and Madison areas.  David Sivyer, Milwaukee’s Forestry Superintendent sent the Tour riders off with thanks for helping to raise money for tree research.  He noted that Milwaukee has still not recovered from the canopy loss due to Dutch Elm Disease and appreciates all the treatment research that has taken place on Emerald Ash Borer. The EAB research helped the city decide to protect more than 27,000 ash trees with TREE-äge® Insecticide.  I was pleased to have the opportunity to connect with Ian Brown who organizes and supervises Milwaukee’s treatment program.

IMG_20140727_080849_601(1)

Wheels Rolling West

We stopped in Waukesha at the E.B. Shurts Environmental Center for a tree planting and dedication. At the dedication, I got a chance to chat with Pete Traczek, the Waukesha City Forester, who has been dealing with EAB and treating for some time.

Heavy Winds on the Way to Madison

The headwinds were strong as we pedaled west through rolling farm land.  The scenery was beautiful and the crops are doing well.  The winds slowed us down a bit but we made it to Madison and are looking forward to tomorrow’s ride.

Provider Spotlight: Ahlum & Arbor Tree Preservation, Hillard, OH

Logo

Chris Ahlum is a second generation arborist who grew up in the family business. His father Dave started Ahlum & Arbor Tree Preservation 37 years ago and today they run the company together. They have approximately 30 employees and cater to high-end residential clients and also do some commercial work.

EAB Entrenched in Ohio

“Our service area in central Ohio covers a seven county area. This includes Columbus and Franklin County, as well as the surrounding areas. Emerald Ash Borer [EAB] is well entrenched in and on its way through Columbus now. We have had to modify our business model around EAB. Our business used to be 80% pruning and 20% removal, and now we are probably more 50/50 in our services. Unfortunately, 85-90% of our removal now is ash trees.”

Despite the challenges, the Ahlums have not given up on Ohio’s ash trees.  They invested in treatment products and this side of the business has increased significantly.

Treating with TREE-äge

“Over the past two years we have started using TREE-äge® Insecticide for nearly 90% of our ash tree treatments. We exclusively use the Arborjet QUIK-jet™ because it is simple to operate and we can train someone to use it quickly. We like that you can see the dose and know it is going in the tree.”
