We were hired to take a look at this gigantic northern red oak (Quercus rubra). The tree's base looked a bit funky, with an irregular flare. We used our resistance drill to measure the extent of decay within the trunk. After taking a few measurements and using a strength loss equation, we found that this tree could be retained for now. #trees #tree #redoak #quercus #oaks #resistancedrill #arboriculture #urbanforestry #forestry #consultingarborist #arborist | Andrew The Arborist
