A tree can be considered for the Great Trees of Union County registry if it is:

• Native to North Carolina, or...

• Successfully introduced to our geographic area and demonstrated longevity

• Not categorized as an invasive species

• Resides in Union County

You can find eligible species on the Eligible Species list. Once a tree meets those criteria, it must meet at least one of the requirements below to earn a spot on the Great Trees of Union County registry.

Most of the trees nominated and accepted will be based on size.

• A total points measurement equal to or greater than 80 percent of the North Carolina Champion Tree of that species.

• Standard points formula is Height in feet + circumference in inches + 25% of average crown spread in feet = total points.

• Ranks as Union County’s three largest trees representing that species

• Find a big tape measure. Measure the circumference of the trunk at 4.5 feet above the ground. Measure all the way around the trunk in inches. For additional information on how to measure your tree visit the Measuring Guidelines Handbook.

• Measure or estimate the height of the tree. Compare with something nearby, such as the roof of a house.

• Measure or estimate the crown spread. If you don’t have a long enough tape measure, pace off the crown in a straight line from each end of the widest part perpendicular to the trunk. A normal adult step pace is about 2.25 feet. Measure the widest part, and then the span that is at a 90-degree angle from that. Add the two and divide by 2 to get the average in feet.

• Take a photo of tree.
