What is the standard specification for Acer platanoides regarding the clear trunk?

The standard specification for Acer platanoides, commonly known as Norway maple, indicates a trunk diameter of 2 inches in caliper, a height of 12 to 14 feet, and a clear trunk free of branches starting at 6 feet. This specification aligns with general industry standards for trees of this species intended for urban planting.

Having a trunk free of branches at an adequate height is crucial for improving visibility and reducing conflicts with pedestrians and vehicles in urban settings. The specified trunk height ensures that lower branches do not obstruct views or pathways, which is important for safety and aesthetic considerations. The caliper measurement of 2 inches ensures the tree is of sufficient size for transplanting and has a better chance of survival and establishment in its new location.

Understanding these specifications helps professionals in selecting the right trees for urban environments, ensuring they meet the necessary requirements for safe and effective landscaping. The choice reflects a balance between traditional practices and modern urban planting needs.
