Connecticut environmental officials are stepping up efforts to keep out firewood that might contain invasive beetles.
Inspections are taking place Friday afternoon at the popular Hammonasset Beach State Park campground to make sure any campers with out-of-state firewood have required permits.
Those without firewood transport permits are being asked to burn the wood immediately.
Officials are concerned about the spread of insects such as the Asian longhorned beetle, which has led to the destruction of hundreds of acres of trees elsewhere.
The insect spends a portion of its life inside the trunk and branches of hardwood trees. It has been found in Massachusetts and New York, but not Connecticut.
Campers are being encouraged to buy firewood close to the campground.
