What is the Lifespan of Trees?

how long do trees live

Living trees are the unsung heroes of our natural world. They stand tall, silently watching over our environment, providing us with clean air, shade on a hot summer day, and a home for countless wildlife. Yet, have you ever wondered how long these magnificent giants can live? Individual trees, like humans, have an average lifespan, and it varies from species to species. So, exactly how long do trees live? Keep reading to find out. Here at Trusty Tree Services in Edmonton, we are passionate about our environment and will delve into the fascinating world of tree lifespans, exploring the factors that influence their longevity and some of the oldest trees in Edmonton.

The Science of Tree Life

Trees are complex organisms, and average tree ages depend on several factors, including their species, health, and environmental conditions. Here are some of the key factors that influence how long a common tree can live:

Species of Trees

Trees come in an astounding array of species, each with its own unique lifespan. Some are like shooting stars in the forest, burning brightly and fading quickly, while others are ancient sentinels that endure through the ages. Consider the giant sequoias found in California's Sierra Nevada mountains. These colossal, ancient trees are renowned for their exceptional longevity, often living for over 3,000 years. Their enormous size and natural resilience have allowed them to withstand the test of time, making them one of the most iconic examples of long-lived tree species on the planet. When compared with some fruit trees which only live for 25 years, you can see that the average tree lifespan varies greatly.


Just as a healthy lifestyle contributes to human longevity, a tree's overall health plays a pivotal role in determining its lifespan. Proper tree care, including regular pruning, soil nutrient supplementation, and protection from diseases and pests, can significantly extend a tree's life. Take, for example, the remarkable bristlecone pines, one of the world's oldest and hardiest tree species. These ancient sentinels, found in the high-altitude, harsh environments of the woods in the western U.S., have thrived for thousands of years due to their unique adaptations and resilience.

Environmental Conditions

Trees are remarkably adaptable organisms, capable of enduring a wide range of environmental factors. From the towering giant sequoias in California to the elegant palm trees swaying in tropical breezes, trees have found unique ways to thrive in diverse habitats, from warm to cold temperatures. Take the oak tree, for example. It grows well in adverse soil conditions, including sandy and loamy soils. However, even ancient giants have their limits. Extreme factors like severe droughts, floods, or extended periods of adverse weather conditions can take a toll on a tree's health and, in some cases, lead to shorter lifespans and premature demise.

Human Impact

Sadly, human activities, such as deforestation, pollution, and urban development, pose a grave threat to the longevity of trees worldwide. Evergreen trees, including the majestic pine trees that adorn many landscapes, are particularly vulnerable to these threats. Historical logging nearly pushed these mature trees to the brink of extinction in some regions. Fortunately, conservation efforts and the establishment of protected areas have helped safeguard these awe-inspiring trees. Recognizing the importance of preserving natural treasures is a crucial step in ensuring they continue to grace our planet for generations to come.

Edmonton’s Long-Lived Trees

Edmonton, with its rich natural beauty and urban green spaces, is home to many long-lived, extraordinary trees. A few notable treasures include:

  • The Old Strathcona Tree: Located in the Old Strathcona neighbourhood, this tree, believed to be a silver maple, is estimated to be over a century old. Its enduring presence serves as a testament to the importance of preserving Edmonton's green heritage.
  • Elm Trees in the River Valley: Edmonton's River Valley is known for its majestic elm trees standing at 60 to 80 feet tall. Some of these elms are well over 100 years old, adding a touch of historical elegance to the cityscape.
  • Mill Creek Ravine Cottonwoods: In the Mill Creek Ravine area, you can find towering cottonwood trees that have stood the test of time. These giants, some dating back to the early 20th century, offer shade and beauty to the local community.
