Are Your Trees and Shrubs Safe from Invasive Diseases?

Are Your Trees and Shrubs Safe from Invasive Diseases?

Davey employee Kyle McLoughlin discusses invasive disease-spreading pests at the Royal Botanical Gardens in Ontario.

Consulting Arborist Kyle McLoughlin, from Davey Resource Group in Ontario, has researched lethal pests for years. He has presented his findings on invasive and endangered species conservation at the Royal Botanical Gardens in Burlington, Ontario.

“I love ecology,” McLoughlin explains. “The research is so fascinating and keeps coming up at work. It’s great to have a career that relates to my passion.”

McLoughlin was invited to lecture at the Royal Botanical Gardens through his connections in the Hamilton Naturalists’ Club, a non-profit organization dedicated to the study, appreciation and conservation of wild plants and animals. He frequently leads interpretive hikes and has presented previous lectures through the organization.

THE LETHAL PEST LIST: McLoughlin’s lectures cover the following invasive species and more, as well as their impacts on the environment.          

  • Emerald Ash Borer (EAB).This is a green beetle killing thousandsof ash trees in the U.S. and Canada. Look for D-shaped holes in the bark and S-shaped tunnels beneath the bark for signs of EAB. In many regions, the most effective time to treat an EAB infestation is in spring.  
  • Dogwood Anthracnose.This is a serious disease of flowering and Pacific dogwood trees all over the U.S. and Canada, and it’s caused by anthracnose fungus. The symptoms for anthracnose include small black dots on bark and twigs and crinkling and browning leaves.
  • Butternut Canker. This is a lethal invasive fungal disease first reported to appear in the U.S. in Wisconsin in the 1960s. The fungus causes tree branches and stems to develop multiple cankers, knocking out a large percentage of the Butternut tree population.

In the future, McLoughlin plans to contact other divisions of the Naturalists’ Club, perhaps Toronto, to present his research and raise awareness about the hidden costs of invasive species, including the impacts on municipal forestry budgets, asset management, taxes and the economy.

McLoughlin and 50 other Davey employees continued their education to learn more about infectious diseases and other tree-related topics at the Davey Institute of Tree Sciences (DITS) training course, which concluded last month. This four-week training program challenged participants with rigorous course and field work that covered several topics, from climbing techniques to insect pests and diseases.

  • Davey Arborist Explains Why Foraging Is More Than Just Fun

    During my work travels over the years, I've had countless opportunities to explore beautiful, unique environments and mysterious forests. As I tread upon the worn paths and trails ahead of me, I take a few moments to study the branches, leaves and bark I brush past and observe along my way.

    I've met many species of wildlife, from deer disguising themselves among tree trunks, hiding from the slight sounds of leaves crunching beneath my soft, slow steps, to birds scouring the earth for food beneath the canopies they call home.

    Some hikers, cyclists and dog walkers, who I've also witnessed frequenting the same paths and trails I often do, seem to enjoy exploring the edible materials they encounter during their outdoor experiences. For some people, their meals depend on Mother Nature's available provisions on any given day.

    Tree limbs drop from bucket truck lifts and cranes as researchers make observations, form calculations and answer questions below.

    While an individual depletes the foliage of a fallen branch by removing its leaves one-by-one, another researcher trims all limbs from the trunk of a tree to test its durability and strength without them.

    The branch of a tree receives a coat of paint before camera software begins analyzing the compression in the bark upon branch movement.

  • Does Emerald Ash Borer Treatment Work?

    Flashback to 2002. A tiny, exotic beetle, identified as emerald ash borer, was just discovered in Michigan.

    By 2009, EAB killed an estimated 58 million ash trees in thirteen states, according to Dr. Leah Bauer of the USDA.

    EAB was once thought to be a death sentence for your trees. Now, we know it’s not. You can treat EAB and save your ash trees.

    Below, we’re answering your most common questions about EAB treatment – with help from our resident EAB expert, Anand Persad of the Davey Institute.

  • Detroit Davey Employees Preserve a Treasured, EAB-Infested Ash Tree

    We all have one tree in our yard – or from our childhood home – that holds the most special place in our heart. The one you planted right when you moved in or the big, stately oak your children used to climb. The one tree you can’t help but smile when you see.

    For Cathy P. in Detroit, it was the tree her late father-in-law had helped her husband plant 20 years ago. But it was time to say goodbye to the tree last fall when emerald ash borer damage threatened its survival. Read below how Davey was able to help keep the memory of her tree alive – even after its demise.
