As with any ecological feature, Trees in Newmarket are vulnerable to pests, disease, and injury. Well-known invasive species and diseases such as the Emerald Ash Borer have done significant damage to certain species. Other fungal infections such as Tar Spot and Cankers can weaken trees or make them appear to be in danger without necessarily causing the death of the tree.

These threats include the Emerald Ash Borer, Cankerworm, and other invasive species and diseases.
