Septimber- Halloween

Pumpkins, black cats and witches are all associated with Halloween without a second thought. As are trees of black gnarled appearance often sporting a rather angry or creepy face. But do their association with the creepy go deeper than the deadly tales of hanging trees and tales of lovers becoming forever entwined?

It could be that the association of trees in graveyards and their tattered look during mid to late autumn brought about many tales to scare children and keep them from the real dangers of playing around graves. Yet, while I can't say for certain that Yew trees keep the devil at bay or even take in lost souls’ other species do keep untoward chemicals and organisms at bay. For example, Willow trees take in nuclear radiation making sites safer over time. Oil from pine trees also dispel the unwanted, they are antibacterial and mildly antiseptic. Alder have a symbiotic relationship with the bacteria, Frankia alni, which takes in nitrogen from the atmosphere making it available to the tree where the nodules the bacterium have created are located.

The most obvious way trees help to clean our environment is their utilisation of carbon dioxide (CO2). A reduction in CO2 reduces many problems faced on our planet including climate change and local air pollution. This in turn improves the health of many people such as asthma sufferers.

So, you see there are many scary things at Halloween and whilst there is always some truth in folklore or myths, rest assured that trees definitely do more good than harm.
