What Kills Our Trees and Why We Shouldn't Neglect Them

Trees in Massachusetts, like in many other regions, are susceptible to a variety of threats that can lead to their decline or death. These threats range from invasive pests and diseases to environmental stressors such as drought and pollution. Understanding what kills your trees and how to prevent these issues is essential for maintaining their health and therefore, your safety.

INVASIVE PESTS

One of the primary threats to trees in Massachusetts is invasive pests, which can cause significant damage to both forest and urban tree populations. The Emerald Ash Borer is perhaps the most notable of these pests. This small beetle attacks Ash trees by burrowing into their bark and feeding on the tree’s tissues. Over time, this weakens the tree, causing it to die. Since its discovery in Massachusetts in 2012, EAB has been a major concern for Ash tree populations, particularly in cities and woodlands where these trees are abundant.

Another invasive pest is the Asian Longhorned Beetle, which targets a wide variety of hardwood trees, including Maple, Birch, and Elm. The larvae of the ALB burrow into the tree, disrupting its vascular system and ultimately causing the tree to die. Massachusetts has experienced outbreaks of ALB, particularly in the Boston and Worcester areas, leading to widespread tree removals in those regions.

To prevent the spread of invasive pests, it is important for residents and tree care professionals to monitor their trees regularly. Treatment options and tree removal, can help control infestations.

DISEASES

Tree diseases are another major cause of tree mortality. One of the most damaging tree diseases is the Dutch Elm Disease, a fungal infection spread by bark beetles that primarily affects American Elms. The disease blocks water and nutrient flow within the tree, leading to wilting, yellowing leaves, and eventual death. Elm trees, which were once a staple of Massachusetts urban and suburban landscapes, have been severely impacted by this disease.

Oak Wilt, another fungal disease, affects Oak trees and is spread through root grafts between neighboring trees or by beetles that feed on infected trees. The disease causes rapid decline, with symptoms such as wilting, browning leaves, and defoliation.

Preventing the spread of tree diseases requires regular monitoring for symptoms of infection and early intervention. Pruning infected limbs, applying fungicides, and removing infected trees when necessary can help prevent the spread of disease.

ENVIRONMENTAL STRESSORS

In addition to pests and diseases, environmental stressors such as drought, pollution, and climate change also contribute to tree mortality. Droughts, especially during the hot summer months, put a significant strain on trees. Without sufficient water, trees become stressed and more susceptible to pest infestations and diseases. Massachusetts has experienced periods of drought, affecting tree health statewide.

Air Pollution from vehicles and industrial activity is another major environmental stressor for trees. Pollutants like ozone can damage tree leaves and hinder their ability to photosynthesize, reducing overall tree health and vitality.

Weather change is increasingly affecting Massachusetts, leading to more frequent and intense tree fall incidents. Storms, floods, droughts, and extreme temperatures are all contributing to tree stress and mortality. For example, prolonged droughts can weaken trees, making them more susceptible to pests and diseases. On the other hand, heavy rainfall and flooding can cause root rot and soil erosion, leading to the uprooting of trees.

Winter storms and ice storms also pose a significant risk to trees, particularly when ice accumulates on branches, causing them to break. These extreme weather events threaten the long-term health of tree populations everywhere.

While climate change is not a local issue, local action can help reduce its impact on trees. Planting species that are more resilient to changing weather patterns is an essential strategy. For example, trees that can tolerate drought or salt (such as the Black Locust or the American Hornbeam) may be better suited to withstand climate extremes. Proper tree care, such as deep watering during drought periods, can also help trees endure tough conditions. Additionally, ensuring trees are properly pruned and maintained to avoid breakage during storms can reduce the risk of damage.

URBANIZATION AND DEVELOPMENT

Urbanization and development pose serious threats to trees, particularly in cities like Boston, Urban sprawl often leads to deforestation, soil compaction, and pollution, all of which can stress trees and limit their growth. Tree roots can be damaged by construction activities, which disrupt the soil and restrict the trees ability to absorb water and nutrients.

Additionally, pollution from vehicles and industrial activities can degrade air quality, leading to weakened trees. Trees in urban areas are also vulnerable to soil contamination, as pollutants from roads and buildings seep into the ground.

Urban planning and development can play a vital role in tree preservation. Creating tree protection zones around construction sites and using techniques like root protection during construction can help minimize damage to existing trees. Governments and city planners can also encourage the planting of more trees in urban environments, focusing on species that can tolerate urban pollution and compacted soils. Public education on the importance of trees and supporting local tree planting programs can also aid in the recovery and expansion of urban tree populations.

INVASIVE PLANT SPECIES + IVY

Invasive plant species can outcompete native plants and trees for nutrients, sunlight, and water. These invasive species often form dense thickets that crowd out tree seedlings and saplings, preventing the regeneration of our trees.

Controlling invasive species is a key part of tree preservation efforts. Invasive plants can be managed through a combination of manual removal, herbicide application, and encouraging the growth of native plants.

Our trees face multiple threats, from pests and diseases to climate change and invasive species. Tree neglect shouldn't be one of them. Preventing tree loss requires a combination of proactive care, responsible check ups and ongoing efforts and tree care to manage the spread of diseases.

Taking good care of the trees on our property helps maintain a healthy environment, providing clean air, shade, and habitat for wildlife. Healthy trees reduce soil erosion, conserve water, and enhance property value.

Our reminder is simple: if we take care of our trees, they last longer. But in some circumstances, tree removal is necessary. Either way, we are here to serve you.
