Vegetation Definitions
Brush Density
Brush density is classified into three categories based on crown cover density. These categories apply to high-voltage distribution lines and border zones of transmission lines:
- Sparse Brush Acres: Areas where tree species have a crown cover density of 33% or less.
- Medium Brush Acres: Areas where tree species have a crown cover density between 33% and 66%.
- Dense Brush Acres: Areas where tree species have a crown cover density greater than 66%.
Centerline Zone
The centerline zone is the area within the transmission line right-of-way, energized at 138 kV or higher, directly below and between the outermost conductors, plus an additional 10 feet on each side.
Danger Tree
A danger tree is any woody species with a mature height of over 20 feet and a trunk diameter of 8 inches or more at breast height (dbh). These trees grow adjacent to the normally cleared transmission right-of-way and could potentially contact the transmission line if they were to fall.
Distribution Brush Unit
A distribution brush unit is a ¼ length of a distribution span containing woody vegetation that can grow over 20 feet at maturity, but is currently shorter than the conductor height within the right-of-way. These units are included in the Unit Brush Work but not in reliability work.
Transmission Brush Unit
A transmission brush unit consists of sparse, medium, or dense vegetation capable of growing more than 20 feet at maturity, located within the right-of-way as identified by the transmission inspection program. It does not include transmission trees.
Transmission Tree
A transmission tree is any tree that:
- Grows to a height of more than 15 feet, with a minimum diameter of 8 inches at dbh in unmaintained areas of high-voltage distribution or transmission rights-of-way, or
- Grows to a height of more than 15 feet, with a minimum diameter of 4 inches at dbh in maintained areas of high-voltage distribution or transmission rights-of-way.
Tree
A tree is any woody species that:
- Grows to a height of more than 20 feet, with a stem diameter of 4 inches or more at dbh for distribution circuits, or
- Grows to a height of more than 15 feet, with a stem diameter of 8 inches or more at dbh for high-voltage distribution and transmission lines.
For reporting and billing, trees near multiple conductors are considered as one. Multi-stem trees that separate more than 2 feet above ground level are treated as one tree if any stem is 4 inches or greater at dbh. Stems that divide less than 2 feet above the ground are counted as separate trees if they meet the 4-inch diameter threshold at dbh.

Andrew Lapeer
I hired Owen to do a tree removal and some pruning for me. Extremely happy with the care they used on my property. I am also using them for my lawn fertilization this year. Arborist seems very knowledgeable.

Owen Tree Service did an outstanding job. The crew trimmed up the treeline and removed several. Did a great job of cleanup too. Extremely professional, informative, helpful & friendly. Thanks so much to the great crew - Ron, Skip, Tim & Doug ... you were incredible. Thanks so much. I'll tell folks about you! (BTW - the guys deserve a few extra $$)
Gayle Rickert

Trish did an exceptional job of assessing the tree removal, trimming, diseased/dead trees, and brush removal on our property. She explained the processes clearly and in detail. Trish is an extremely knowledgeable arborist. I highly recommend her to give a comprehensive review & estimate of your landscape needs.
Linda Janiszewski
Punctuality, Quality, Professionalism, Value
We are very happy with the work they did. We had a large birch tree trimmed that had power lines on each side. There were 4 workers and they worked well together as a team to get the job done. They cleaned up the yard around the tree and did a professional job. They also asked us if we liked it before they left. We would highly recommend Owen Tree Service!

I have used Owen for over 10 years. They take care of my Apple tree, shrubs, lawn irrigation and weed/fertilizer. I have always found them to be price competitive, thoughtful and timely. 5 stars from me!
