Short Answer
Birch trees have white bark due to their outer layer of bark cells that contain a white, waxy substance called ‘lenticel’.
This wax helps the tree to reduce water loss and protect against the elements.
Lenticel also reflects sunlight which helps to keep the tree cool and prevent sunburn.
The white bark also helps the tree to stand out in the forest, making it easier to identify.

Reflecting Light for Cooler Temperatures
Birch trees are known for their unique white bark which stands out in contrast to other trees in the forest.
But why is this white bark so important? The answer lies in the trees defense mechanism: the bark helps protect it from sunburns, insects, and also reflects light.
By reflecting light, the tree keeps itself cooler in the summer months, allowing it to survive in the forest.
This reflective quality of the white bark helps the tree to stand out from other trees in the forest.
The bright white color helps animals and birds to easily spot the tree, allowing them to use the branches for food.
This is why birch trees are such an iconic sight in many forests and their white bark is one of the main reasons why.
In addition to reflecting light and helping the tree stand out, the white bark also has antimicrobial properties that help protect the tree from disease and infection.
The bark also helps control the level of moisture around the tree, which is important for survival in dry climates.
All in all, the white bark on birch trees is a multifaceted defense mechanism that helps the tree survive in the forest.
