Another busy year of science in Acadia National Park in the books! Researchers worked on 85 projects in the park. Researchers included technicians, Gero Fellows, Second Century Stewardship Fellows, Scientist-in-Park interns, NPS and Schoodic Institute staff, student teams from Worcester Polytechnic Institute, and faculty and students from College of the Atlantic, University of Maine, and other partners in science.

In 2022, we began to scale-up three big ecosystem restoration projects in the park—on the summit of Cadillac Mountain and at Great Meadow (Acadia’s largest freshwater wetland) and Bass Harbor Marsh (the park’s largest salt marsh). These restoration projects built on six years of work on the Wild Acadia initiative with Friends of Acadia and the science expertise of the Schoodic Institute, the nonprofit that supports the Research Learning Center in Acadia. The projects are notable for their scale—some of the largest resource management projects in the park’s history—and for their approach. Rather than restoring past conditions, the restorations include a mix of actions, some to resist changes like invasive plants, some that accept changes like increased rainfall, and some to direct changes like promoting species adapted to future climate conditions. This resist-accept-direct approach is called RAD for short and represents a new approach for climate adaptation for conservation organizations.

An analysis of long-term Christmas Bird Count data showed sharp declines in winter bird populations in Acadia. In 2021, an analysis of NPS monitoring data showed surprising changes in summer breeding bird populations, too. Understanding these changes and their implications is becoming a priority for park managers, and is a subject of expanding research, as reflected in increases in wildlife-focused research in 2022, a trend we expect to continue.

Acadia staff are also exploring ways to reduce threats to aquatic wildlife. For example, how do we protect salamanders who cross park roads to reach vernal pools to breed in? And how might we manage nonnative invasive fish to protect native species and to reduce harm from mercury pollution?

Park staff are also working with local communities on projects in the intertidal zone. Officials from the Town of Mount Desert, College of the Atlantic, Schoodic Institute, and NPS worked together to understand options for improving the health of the harbor at Otter Creek, a historic fishing village adjacent to the park. Park and Schoodic Institute staff also continued their work to improve management of threatened intertidal ecosystems, which are important for Tribes, clam and marine worm harvesters, visitors, and educators.

The buzz of research activity was not limited to the field. Scientists published at least 38 new publications about research in Acadia, more than in most years. Perhaps people had more time to analyze data and write over the past year because of COVID-19 or perhaps this reflects increases in research in Acadia over the past decade.
