A tree audit commissioned by the city of Dunwoody found all of the trees in the dog park area of Brook Run Park could die within seven to 10 years if nothing is done to help them.

The study, which assessed roughly 1,000 of the most prominent trees in Dunwoody’s parks and rights of way, found that 82 percent were either in fair condition, poor condition or dead.

Though 56 percent were in fair condition, the report concludes most trees in fair condition merely need pruning to remove dead limbs.

“In general, the forest that the city of Dunwoody lives within is found to be in good health,” the report states.

The report recommends creating a maintenance schedule focusing on the most pressing areas first. The playground and dog park areas of Brook Run Park were found to be a priority due to the high traffic that compacts the soil around the trees.

“Due to the severe soil compaction, these soils are droughty, and a significant portion of any rainfall landing in the area simply runs off the soil surface, leaving little to no water for usage by the trees,” according to the report. “In many locations, the buttress roots of large trees are being exposed as a result of soil erosion, and damage to these roots is occurring from pedestrian traffic and chewing by dogs.”

The city plans to relocate the dog park to another area of Brook Run next year as part of a larger effort to create a trail system through the park.

Mayor Mike Davis said he suspected the dog park was causing damage to the trees.

“The sooner we get that dog park out of there the better,” Davis said.
