An Interior Department report released Tuesday found that a scientist at Point Reyes National Seashore committed misconduct by misusing photographic evidence that appeared to contradict her contention that an oyster farm’s operations disturbed harbor seals. “This misconduct arose from incomplete and biased evaluation” of the evidence, wrote Gavin Frost, an attorney-adviser in the solicitor general’s office. The identities of the two, Sarah Allen, and her superiors — including Jon Jarvis, director of the National Park System, were obtained independently by The New York Times and other news organizations. Mr. Frost said that despite misconduct the two had not violated any law. The Drake’s Bay Oyster Company has a lease to operate in the Point Reyes park until next year. The Park Service is reviewing what effects a lease extension might have on the environment.
