Trees are an extremely common sight all over Australia, from the most tropical locations in the Northern Territory to the drier landscape of the outback.

If you live in an area with little rainfall each year, then increasing temperatures might make you worry for these plants.

As professional tree loppers and preservers, Hunter River Trees can help you to understand exactly what happens to trees during a drought, and what to look out for during the dry season.

Trees and moisture

Just like human beings, trees need moisture to survive.

The primary way in which they photosynthesise is by drawing up water into the leaves and then exuding it through small pores within each leaf.

The water is then dispersed into its relevant molecules, and glucose is made.

Carbon, which is also necessary to photosynthesis, is also absorbed at this time

Dying of thirst 

During a drought, the most obvious problem that occurs in trees is purely thirst.

The tree pulls up water through it's roots which then supply every part of the tree, and in times of drought, they simply not enough water in the ground to survive.

This failure to transport water from the roots to the leaves is known as a hydraulic failure.

The tree simply dries out, in the same way that a plant left on the windowsill without water will do.

Dying of hunger

Obviously, because trees rely so much upon water to feed themselves, it can be very hard for them to manage during dry weather.

The hydraulic failure may also trigger a secondary problem caused by the trees closing the small pores in the leaf surface to avoid losing too much liquid.

Because these pores need water to remain open, it then makes it hard for them to absorb carbon dioxide, and so they are left without being able to manufacture glucose.

Almost half of all trees that die during droughts have no reserves of carbon just before they die.

How to overcome tree death

There are several ways in which you can help trees to overcome these problems during a drought.

The first is clearly to water the plants as much as possible.

Secondly, you can seek advice from Hunter River Trees.
