Key Takeaways

  • The emerald ash borer (EAB) is an invasive pest that causes significant ecological and economic damage to ash trees across North America, threatening their survival.
  • Early identification of EAB infestations, such as crown dieback and exit holes, is crucial for effectively managing and controlling its spread.
  • A multifaceted approach combining biological control, chemical treatments, and cultural practices is essential in mitigating the impact of EAB and preserving ash tree populations.

Understanding the Emerald Ash Borer (EAB)

The emerald ash borer (EAB) is a pesky and invasive beetle that is responsible for significant damage to the ash tree species across North America. It originated from East Asia and was introduced to North America via shipping materials like crates and pallets. First detected near Detroit, Michigan, in 2002, it has since spread rapidly across many eastern and Midwestern states in the U.S.

EAB specifically targets ash trees, feeding on the layers of tissue beneath the bark. This feeding disrupts the tree’s ability to transport water and nutrients, ultimately leading to its death. The emerald ash borer is capable of killing ash trees of any age and condition, posing a significant threat to both urban and forest ecosystems. In fact, once EAB establishes itself in an area, it can kill up to 99% of the ash trees within 8 to 10 years, transforming vibrant forests into desolate landscapes.

The impact of EAB affects multiple ash tree species, including black ash trees, green ash, and blue ash. This widespread vulnerability has led to a significant decline in many ash tree populations, with severe ecological and economic consequences.

Understanding the nature of this threat is the first step in combating it and preserving our valuable ash tree populations, especially since it kills ash trees.

Life Cycle of the Emerald Ash Borer

The life cycle of the emerald ash borer (EAB) is fundamental to its destructive capability. EAB undergoes four life stages: egg, larva, pupa, and adult. Adult beetles emerge and fly from late May to early September, with peak activity in June and July. These beetles, measuring 3/8 to 5/8 inches long with bright metallic green wings, are the most visible stage of the EAB.

The real destruction, however, occurs during the larval stage. EAB larvae, which are cream-colored and can grow up to 1.5 inches in length, feed on the inner bark and phloem of the ash tree, creating S-shaped patterns inside the wood. This feeding, known as larval feeding, disrupts the tree’s nutrient and water transport systems, leading to the tree’s decline and eventual death.

Larvae remain in the tree for 1 to 2 years before pupating. The pupae, creamy white and 10-15 mm long, eventually transform into adult beetles, completing the life cycle.

Identifying Emerald Ash Borer Infestations

Early identification of an emerald ash borer infestation can significantly aid in managing and controlling its spread. Distinct signs include crown dieback, where dead branches become visible at the top of the tree, progressing downward, signaling severe internal damage.

D-shaped exit holes on the tree bark, created by emerging adult beetles, are another clear indication of an EAB infestation. These holes are roughly 1/8 inch in diameter.

Increased woodpecker activity around ash trees can also indicate EAB presence. Woodpeckers feed on larvae beneath the bark, leaving light patches on the tree’s surface. Observing these signs early and accurately can lead to quicker, more effective responses to infestations.

How EAB Spreads

Both natural and human factors facilitate the spread of the emerald ash borer (EAB). Initially, EAB was accidentally transported to North America in infested crates and pallets, a consequence of global trade. Once established, EAB adults can travel considerable distances during their active flight season, which typically begins in late spring. Natural factors, such as wind, can also aid in the dispersal of EAB adults over short distances.

Human activities greatly contribute to the long-distance spread of EAB. Moving infested wood products like firewood and lumber has been a major factor in its spread to new areas. Infested ash trees serve as reservoirs, enabling these tree insects to establish new infestations wherever these materials are transported.

Since its detection in 2002, EAB has spread to over 30 states and 5 Canadian provinces, highlighting the extensive reach of this invasive species.

Distribution and Habitat

The distribution of the emerald ash borer (EAB) has expanded significantly since its initial detection in North America. EAB has now been detected in 36 states and the District of Columbia, establishing itself as a widespread threat to ash trees. Notable detections include Connecticut in 2012 and Kentucky in 2009, illustrating its rapid spread.

EAB affects various habitats, from urban landscapes to natural forests. In New York State, native ash species such as white, green, and black ash are threatened. In areas affected by EAB, nearly 99% of ash trees may die within a decade, drastically altering forest compositions and ecosystems.

The extensive presence of EAB underscores the need for rigorous management and control measures to protect these valuable habitats.

Environmental and Economic Impacts

The environmental and economic impacts of the emerald ash borer (EAB) are profound and far-reaching. EAB has killed millions of ash trees across North America, severely disrupting ecosystems and reducing biodiversity. The death of tens of millions of ash trees has altered forest compositions, making them more susceptible to other invasive species and affecting overall ecosystem health.

Economically, the loss of ash trees in urban areas has posed significant challenges. Municipalities face increased costs for tree removal, replacement, and management, leading to substantial financial burdens. In southeastern Michigan, the economic impact of removing thousands of dead trees has been immense. Additionally, the damage caused by EAB larvae leads to public safety hazards as trees decay, creating liability issues for communities.

Regulations and Quarantine Measures

Various regulations and quarantine measures have been implemented to combat the spread of the emerald ash borer (EAB). In New York, state quarantines are imposed in most of western New York and certain counties to limit the movement of ash trees and related products. These regulations aim to prevent the further spread of EAB by controlling the transportation of regulated materials, including all parts of ash trees and firewood from any species.

Compliance agreements and certifications are required for moving regulated materials out of quarantined areas, with restrictions on items like wood chips and bark mulch larger than one inch. Properly disposing of infested ash trees through methods like chipping or burning is vital to prevent the spread of the Emerald Ash Borer (EAB). Avoiding the movement of infested firewood is also essential in curbing the long-distance dissemination of this invasive species.

Management and Control Strategies

Managing and controlling the emerald ash borer (EAB) requires a multifaceted approach. Strategies include biological control, chemical treatments, and cultural practices, each playing a key role in protecting ash tree populations and mitigating the impact of EAB.

Biological Control

Biological control uses natural enemies to manage invasive pests like the emerald ash borer (EAB). This method reduces reliance on chemical treatments and can include predators such as woodpeckers and certain beetles that prey on EAB. Parasitoids, which lay eggs in or on EAB larvae, are also used; their offspring kill the larvae, effectively reducing EAB populations.

However, introducing natural predators and parasitoids can have unintended ecological effects, potentially disrupting local ecosystems.

Chemical Treatments

Chemical treatments are another key strategy in combating EAB. Insecticides such as imidacloprid and emamectin benzoate are often used to protect healthy ash trees from EAB pest attacks. These insecticides can be injected directly into the tree or applied as soil drenches, allowing the chemicals to be absorbed and translocated within the tree.

If applied timely, some insecticides enable tree recovery even after significant EAB damage.

Cultural Practices

Cultural practices are crucial for preventing the spread of EAB and maintaining healthy ash tree populations. Proper disposal of infested trees through methods like chipping or burning helps eradicate EAB and stop its spread. Additionally, selecting tree species resistant to EAB is an effective cultural practice.

These practices form an integral part of a comprehensive EAB management strategy.

The Role of Citizen Scientists

Citizen scientists are pivotal in tracking and managing emerald ash borer (EAB) infestations. Community involvement, including tribal perspectives, is emphasized in managing and conserving ash tree resources. U.S. Forest Service scientists are seeking efficient monitoring techniques for EAB, and citizen scientists can significantly contribute to these efforts.

Reporting signs of EAB is vital. Individuals can use report forms or call dedicated hotlines to report new infestations. This grassroots approach helps track the spread of EAB and informs management strategies, making citizen scientists an invaluable part of the fight against this invasive species.

Future Prospects for Ash Trees

Why Is Half of My Tree Dead?

Half of a tree dying from disease

Your half-dead tree can cause a significant accident or infect the rest of your yard if you are unaware of its cause. By first knowing why your tree is dying, you can take action that may save it from falling and causing significant damage to your property.

toddsmariettatreeservices.com gathered information about the causes and treatments for a tree that is half dead.

My Tree Is Dead on One Side

You may be asking, “How can a tree die on one side?” Several possibilities can lead to this condition, and all of them require immediate action. For deciduous and evergreens alike, consider the following causes and their treatments:

Tree Diseases

Verticillium Wilt – Verticillium wilt is caused by a fungus called Verticillium dahliae or another less common species, Verticillium albo-atrum. This soil-borne fungus germinates when plant or tree roots grow near it, infecting them through wounds or natural openings. The fungus spreads through the host’s vascular system and causes the plant cells to clog themselves. Once the xylem is infected, water can no longer reach the leaves because of the clogging.

Treatment: This disease is challenging to manage because it persists in the soil indefinitely. Infected trees that are not yet dead can sometimes survive the fungus. Dead or affected branches should be removed to help the tree regain its vigor. However, this disease can be transmitted on unsterilized pruning tools.

In cases where an entire side of a tree has succumbed to the disease, the tree should be removed before falling during a storm or unexpectedly.

Fusarium Wilt – Commonly found worldwide, Fusarium wilt is a soil-borne pathogen Fusarium oxysporum that enters its host through the roots and interferes with its water-conducting vessels. As the disease spreads into the stems and leaves, it restricts water and nutrient flow, causing the foliage to wilt and turn yellow.

Treatment: Similar to Verticillium wilt, affected stems and branches should be removed. Fusarium wilt can also be treated with biological fungicides.

Phytophthora Root Rot – Many tree and shrub species are susceptible to Phytophthora root rot, developing root and/or crown rot, mainly if the soil around the base of the plant stays wet for long periods. The leaves of an infected tree will appear drought-stressed and may die quickly in late spring or early summer.

Treatment: You can combat Phytophthora root rot by increasing soil drainage, pruning out affected branches and stems, and by maintaining the root flare of the tree free from soil, mulch, and debris.

These diseases are easily transmitted from one host to the next by overhead watering or splashing, pruning activities with unsterile equipment, and improper disposal of infected clippings.

Environmental Causes of Tree Decline

Soil Compaction – Soil compaction occurs when heavy equipment, machinery, vehicles, or other factors lead to the compression of the soil surrounding a tree. Soil compaction reduces the amount of air, water, and nutrients available to tree and plant roots.

When tree roots on one side of a tree are impacted by soil compaction, an entire side or portion of the tree can wilt and die.

Treatment: Avoid parking, driving, or storing any vehicles or heavy equipment near or under any tree. Once the soil is compacted, a professional tree service should be hired to aerate the soil and monitor the health of the impacted tree.

Lightning – If it doesn’t blow it up, a lightning strike can severely compromise a tree’s vascular system by vaporizing the liquid within it. Depending on the location of the strike and how it travels through the tree, only a portion of it may be impacted.

Half of a tree dying from a lightning strike

Treatment: If you suspect that your tree has been struck by lightning, have a tree hazard assessment performed immediately to assess the need for treatment or removal. Read more about tree hazard assessments at toddsmariettatreeservices.com/why-do-i-need-tree-hazard-assessment/

Surface Root Damage – Due to erosion, poor soil quality, or improper watering, tree roots may surface over time. When these roots are damaged or pruned, they are highly vulnerable to infection by opportunistic diseases like Fusarium, Verticillium, and Phytophthora.

Half of a tree dying from damaged and diseased surface roots

If surface roots on only one side of the root plate become infected, only a portion of the tree will likely display symptoms of infection, decline, or death.

Treatment: If the roots cannot be buried, they should be protected from damage by people or machinery. Once surface roots are damaged, a professional tree service should be called to evaluate the situation and recommend a course of action.

Stem Girdling Roots – Stem girdling roots are dysfunctional roots that circle the stem (trunk), choking off the flow of nutrients and water between the roots and the rest of the tree. They can also compress and weaken the trunk of a tree at the root collar, causing it to lean and lose stability. Trees with stem girdling roots are at a significant risk of declining health, premature death, n and falling suddenly.

Treatment: Stem girdling roots can be removed by using saws or pruners if they have not caused extensive stem compression. If one has caused severe damage, removal treatment must include measures to avoid damaging the stem. These roots are frequently left in place when their removal cannot be performed safely. It may be necessary to consult with a professional tree service to determine what coarse of action to take.

Boring Insect Infestations

Boring insects like beetles can quickly cause the decline of a portion of a tree. As they burrow through the tree’s bark, they will sometimes begin channeling through the xylem and phloem. In other cases, they may burrow into the heartwood of the tree, carrying fungi with them that infect the tree and disturb the flow of water and nutrients from the roots to the rest of the tree.

Half of a tree dying from boring insect infestation

While initial symptoms may only appear on one side of the tree, the tree will eventually succumb and die, as more beetles successfully attack the tree as it weakens.

Treatment: Once a tree has been successfully attacked by beetles, treatment is challenging and will likely result in the removal and destruction of the infected tree. Most treatments for beetles are preventative and include:

• Setting traps
• Treating the bark of un-infested trees
• Removal and disposal of infested trees

However, the most exceptional line of defense for a tree is its health. In the case of insects or diseases, healthy trees can resist infestations and infections. Help your tree by:

• Watering it regularly
• Proper seasonal pruning
• Mulching with organic material
• Fertilizing when necessary
• Having it inspected annually

Half of My Tree is Dead

In this article, you discovered what can cause half of a tree to die and what actions to take to either treat the tree or have it removed.

By taking immediate action when you notice the decline of your tree or a portion of it, you increase the possibility of saving the tree and returning it to a healthy state.

When you ignore the symptoms of disease or infestation, your tree can rapidly decline and die. Trees left untreated are more likely to fall during storms, causing catastrophic damages when landing on property, vehicles, and people.
