Quercus virginiana | Santa Barbara

A very nice Southern Live Oak (Quercus virginiana) in Santa Barbara. The supplemental irrigation provided by the nearby lawn is likely providing this tree with some welcome summer moisture. This juxtaposition,  with the tree on one side of a sidewalk, and a water source on the opposite side, usually leads to substantial sidewalk damage. This damage varies by soil and construction techniques. Here, no pavement uplift can be discerned, which is likely attributable partly to soil, and a lack of overcompaction beneath the sidewalk. This also is potentially indicative of Southern Live Oak being less destructive of infrastructure than many other trees, a pattern which has been seen in other locations.
