There's concern that it's being done to improve the view from an exclusive sub-division nearby.
Park rangers say eight trees were hacked off at McNear's Beach Park. They discovered the damage 10 days ago.
Rangers suspect homeowners living above the beach are to blame since it's their vista that directly benefits.
They say the tree trunks were stripped clean of limbs.
The cutters left evidence of spikes from special climbing shoes and ropes.
