[MAIPC] Tree assessment

[Marc Imlay]

At my 200 acre Ruth B. Swann Park in Charles County, 10 years ago I finished removing all the English Ivy, Japanese honeysuckle, and oriental bitter sweet climbing high up trees. 4 years ago I finished all the other ones climbing up the trees and all the long specimens on the ground.  Now I am removing all the remaining small ones on the ground. All the mile-a-minute was eradicated 10 years ago and it has not come back.

PlantNOVATrees is working on creating an assessment of the at risk trees in Northern VA. We are attempting to follow some of the same guidelines as was present in the recent Takoma Park, MD study which found 5,000 at risk trees in a 2 square mile area. But, we are stumbling on how to define an at risk tree. The definition so far states that a tree is at risk if there is concern it will succumb within 5 years to the NNI vines if no action is taken. Obviously a mature canopy tree with only a few vines as the base would be considered a low risk and a tree smothered with vines a high risk. But, does anyone know if there is any standard that can be utilized (% of trunk covered with evergreen vines, etc) for trees in between. It may vary with species and/ or type of vine. We are currently reaching out the primary group that did the Takoma Park study, but also wanted to get input from others. 

 

Thank you

Heidi
