Atlanta Drought is Trial by Fire for Trees

After months of little rain, trees around the Atlanta area are beginning to look a little parched.

The weakest trees are the ones that succumb to moisture stress first. Sometimes its the trees that have been damaged from soil disturbance, such as on construction sites or even on lawns that have been over-manicured. Construction sites may have compacted soil that drives out pore space in the soil. Over manicured lawns may have been over-watered in the past or been graded by machinery that destroyed fine roots in the upper strata of the soil profile.

Trees growing in regions that are already dry may be on the edge of critical moisture stress. A casual drive through south DeKalb County reveals Loblolly pines dying on the rock outcrops.

Atlanta Council proposes significant change to tree ordinance

On June 17, The Atlanta City Council made a striking modification the City's tree ordinance.

Property owners will now be allowed to remove any tree that is growing within 5 feet of a house or duplex, without recompense.
