What It Means If You See a ‘Girdled’ Tree in New York State

This spring, New Yorkers may see something odd in their local forest... have you heard of tree girdling?

Every environmental problem has its own unique solution. From the "banded" trees that are fighting invasive insects to the extensive lengths hikers have gone to protect their cars from hungry porcupines, the creativity is endless. Girdled trees, however, are taking things a step further.

Girdling Trees in New York State

Girdling is a process that shouldn't be taken lightly, as it will eventually kill the targeted tree. Often used as an option over felling a tree, girdling interrupts the pathway of nutrients between the roots and the branches above. One tree in particular has had a target on its back for this specific process.

Invasive Norway Maple Tree in New York

The Norway maple is an invasive species of maple tree that has spread to nearly half of the United States. Similar to the frustrating (and often illegal) Bradford pear tree, the Norway maple was originally an ornamental tree that has quickly began to cause problems for local ecosystems.

Problems with the Norway Maple tree in New York State

Not only do Norway maples spread quickly, but the shade created by their significant leaf canopy can inhibit the growth of native trees like the white pine (above). If shade reduction is the goal rather than full removal of the tree, girdling can be a helpful option.

The Norway maple is not a desired lumber source, so repurposing the trees in other manners is not a helpful option. Conservationists also note that girdling Norway maples instead of removing them completely can be beneficial for wildlife who can use the trunks to make their homes.
