Lightning Strikes on Trees

Written by Down To Earth | Apr 10, 2023 1:39:39 PM

Florida is known as the lightning capital of the world due to its frequent and intense thunderstorms, which can produce large numbers of lightning strikes. This is mainly due to Florida's unique location and geography, which make it a hotspot for thunderstorm activity. Florida is situated between the Gulf of Mexico and the Atlantic Ocean, creating a unique environment conducive to thunderstorms. 

The warm, moist air from the Gulf and Atlantic collides over Florida, which can create instability in the atmosphere and lead to the formation of thunderstorms. This process is further enhanced by the state's warm climate and abundant sunshine, which helps heat the air and create the conditions for thunderstorms. Thus, incidents like lightning striking over the trees in this region are common.

Interestingly, some palm species are more susceptible to lightning strikes than others, and the reasons for this are not entirely clear. However, some factors may increase the likelihood of a palm tree being struck by lightning. The article discusses this phenomenon and ways to treat the trees met with lightning strikes. Now, let's begin: 

Heat and Speed of Lighting 

Lightning is an electrical discharge that occurs when there is a buildup of electric charge in the atmosphere. It can occur within a single cloud, between different clouds, or between a cloud and the ground. The heat and speed of lightning can vary depending on the type of lightning and the conditions under which it occurs.

The temperature of lightning can reach up to 30,000 Kelvin (53,540 degrees Fahrenheit), which is hotter than the sun's surface. This intense heat causes the air around the lightning bolt to expand rapidly, creating a shock wave we hear as thunder.

The speed of lightning varies depending on the type of lightning. Cloud-to-cloud lightning can travel at speeds of up to 220,000 miles per hour (354,055 kilometers per hour), while cloud-to-ground lightning can travel at speeds of up to 220,000 miles per hour (354,055 kilometers per hour). This is faster than the speed of sound (about 767 miles per hour or 1,234 kilometers per hour at sea level).

Why is Understanding the Symptoms of Lightning Strikes Important? 

Professionals in the landscaping and arboriculture industries need to distinguish the symptoms of lightning strikes on trees from other causes, as it can affect their management decisions and treatment options. The symptoms of lightning injury can be variable, but some common signs to look out for include:

  • Bark damage: Lightning can cause the bark to split or peel away from the tree trunk in a distinctive pattern that is often described as "stripped."
  • Scorching: Lightning can cause a tree's leaves to become scorched or singed, often in a pattern that follows the path of the electrical current.
  • Canopy damage: Lightning can cause significant damage to a tree's canopy, including broken or stripped branches and even the complete loss of leaves in severe cases.
  • Stunted growth: In some cases, lightning strikes can cause a tree to experience stunted growth, which may be noticeable in the form of smaller leaves or branches than normal.
  • Root damage: Lightning can also cause damage to a tree's roots, which may result in reduced vigor or growth and increased susceptibility to other pests and diseases.

It is important to note that some of these symptoms can be confused with other causes of tree damage, so it is important to consult with a certified arborist or other tree care professional to accurately diagnose the issue and determine the best course of action.

Lightning Protection Systems

Lightning protection systems (LPS) are designed to protect buildings and other structures from the damaging effects of lightning strikes. These systems are typically installed on tall buildings, bridges, communication towers, and other structures that are at a higher risk of being struck by lightning.

The basic principle behind a lightning protection system is to provide a low-resistance path for lightning to follow, which diverts the electrical current away from the structure and safely into the ground. This is typically accomplished by installing a network of conductive materials on the roof, walls, and other structures connected to a grounding system.

The key components of a lightning protection system include:

  • Air terminals: These are pointed rods or other structures that are installed on the roof and other high points of the structure. They attract lightning strikes and provide a path for the electrical current to follow.
  • Conductors: These are metal cables or other materials that connect the air terminals to the grounding system. They provide a low-resistance path for the electrical current to travel.
  • Grounding system: This includes a network of metal rods or other materials that are buried in the ground around the structure. The conductors are connected to the grounding system, which provides a safe path for the electrical current to dissipate into the ground.
  • Surge protection devices: These are devices that are installed on the electrical and communication systems within the structure to protect them from the damaging effects of lightning strikes.

It is important to note that trained professionals must install and maintain lightning protection systems to ensure their effectiveness. Additionally, while these systems can significantly reduce the risk of damage from lightning strikes, they do not guarantee complete protection, and it is still important to take other safety measures during thunderstorms, such as seeking shelter indoors or in a fully enclosed vehicle.

Snags

Snags or standing dead or dying trees are important ecological features in many natural and managed landscapes. While snags can be critical environmental features, they can also pose safety risks in certain situations, particularly in urban areas where they may be more likely to fall and cause property damage or personal injury. 

As a result, it is essential for land managers and arborists to carefully evaluate the risks associated with standing dead or dying trees and determine the appropriate management actions to take.

Grinding up the stump after a tree has been removed can effectively prevent the stump from becoming a food source for the fungus that causes Ganoderma butt rot. This is because the fungus that causes Ganoderma butt rot can often invade and thrive on decaying wood, particularly the root systems of dead or dying trees.

Conclusion 

Lightning strikes on trees can significantly impact the trees and the surrounding environment. Lightning is a powerful natural force that can travel great distances and strike objects with incredible detail. When lightning strikes a tree, it can cause a wide range of damage, including trunk and branch damage, root damage, and even total destruction of the tree.
