Re Cheinne’s link (Good read)
“Trees are allowed in Zone 0 as long as they are maintained and their lower branches are pruned to
prevent fire from climbing into the canopy of the tree. Maintained trees cannot have dead and dying
branches, and no branches should be within 5 feet of the roof or walls or 10 feet of chimneys.
“Single specimen” trees (or live trees that stand alone and where there is no vertical overlap with the
canopy of other trees, and lower branches are pruned to prevent ignition) and trees protected by local
ordinance have exceptions from the regulations.”
