WASHINGTON — Rep. Joseph E. Brennan said Thursday that the National Park Service has shortchanged Acadia National Park, giving it far less operating revenues than comparable national parks.

Testifying at a House hearing, Brennan said that the proposed 1991 budget for Acadia would leave a $1.7 million shortfall.

Despite being the second most popular park in the national system — with 4.7 million visitors last year — federal funds to Acadia totaled only 46 cents per visitor.

The national average for all national parks, Brennan said, is $4.52 per visitor.

“Acadia has been forgotten by the Park Service, by the administration, and regrettably, by Congress,” Brennan said. He warned that continued inadequate funding could result in a deterioration of Acadia’s natural and cultural resources.
