Best Review reported in May that falling trees cause property damage of $3 to $5 billion annually in the US. Think of smashed cars and buildings. But the good news is that three-fourths of trees that fall during storms show signs of pre-existing damage before the fall that's often correctable. If you have mature trees near your theatre, it's time to give them a check-up. 

Here are some signs of poor tree health:

Root Damage - Damage to roots is most easily detected above ground. Signs include branches that start dying at the tip or trunks that lean enough to need bracing.

Co-dominant Stem - A tree with two main trunks is structurally unstable and at a high risk of falling.

Excessive Lean - Many trees lean, but those with evidence of root lifting, soil mounding, cavities, cankers or decay are cause for concern.

Wounds - Trees attempt to close and compartmentalize wounds, but cavities, cankers or decay on more than 40% of the circumference can affect stability.

Longitudinal Cracks - Longitudinal cracks, especially ones that start at a branch union, can be dangerous.

Recent Excavation within the Drip-Line - Excavation or construction within the drip-line damages feeder and anchoring roots, which weakens a tree, increases its susceptibility to disease and insects, and makes it less stable and resistant to wind.

If you see any of the these conditions, have a certified arborist evaluate your tree to determine if it can be saved or if it should be removed before it crashes into your home or business.
