Our clients ask us many questions. One of the most perplexing is, “Do trees die of old age?” The reason it’s confusing is that trees don’t age in the same way we do.
Read on as California’s 3 Dads Tree Service, your go-to tree service in Crescent City, explains the factors influencing tree life span.
Can Trees Succumb to Old Age?
Yes, trees can succumb to old age in the same way as humans can. The trees develop structural defects and eventually just cave in on themselves.
However, there’s also a lot more to understanding tree longevity. Plus, most trees won’t reach a ripe old age because of environmental factors or human intervention.
The Aging Process in Trees and Mortality
The main difference between plant and human aging is that, in the human body, our cells age. Plants don’t function in the same way. For example, when your tree matures, the roots are quite far from the branches, and this vascular tissue takes up a lot more space.
The problem with this setup is that, eventually, the tree develops more non-photosynthesizing tissue than foliage. As this balance tips, you’ll notice the following:
- The tree will start to struggle to produce enough energy to sustain itself.
- It becomes impossible for the tree to support the vascular layer that protects the heartwood.
- This layer starts to die off in places, and with older trees growing ever-slower, they can’t repair the damage fast enough to protect the heartwood.
- The heartwood becomes vulnerable to decay, and rot sets in.
It’s this tree aging and end-of-life phase that spells the end. In a healthy tree, the plant compartmentalizes the damage and lays down a new layer of cambium. With older trees, there’s too much surface area damage to contend with.
The Lifespan of Trees and Natural Mortality
Do trees die of old age? Another reason that the answer is complicated is that some species live much longer than others. For example, there is a Bristlecone Pine in the United States that’s over 4,500 years old, whereas common Pine trees only reach about 100 years old.
Growth Rate
Primarily, the difference is down to redundant systems and hormone signals, which tell the plant when to expend energy toward growing and when to produce flowers and seeds instead. Many scientists believe that the long-lived tree species are better at storing energy. They often don’t grow as fast.
Natural Selection
The other factor is that, in nature, older trees are less capable of surviving drought conditions. They have more bulk to support and need the water to do so.
Similarly, storm damage to the canopy may cause too many roots to die off. So, in either condition, the tree will lose ground, and younger, more vigorous plants will claim its precious resources.
