I have inspected the Stonebridge site both from above and below. I estimate the urban tree
canopy to be 80 to 82% coverage. This is relatively high for an HOA located in an urban setting.
do not believe that planting any additional Aleppo pine trees would benefit the Stonebridge
HOA at this time. The Aleppo pine is a large tree with a large canopy. Planting small to medium
trees to supplement the existing landscape would allow for a multi storied canopy, with
diversity, better aesthetics and a healthier landscape. It would also allow the existing trees to
mature with less pruning and less stress which occurs from pruning.
In addition, with such a dense tree canopy it makes it difficult to maintain the understory
landscape. The canopies shade out the shrubs underneath which then require additional
disease and pest control and fertilization. Pruning could remedy the situation but would have to
be done annually to be effective and as mentioned above would causes unnecessary stress to
the trees. For the reasons mentioned above I am recommending not to replace the Aleppo
pines with the same species.
