Located along the mid-coast of Maine, Acadia National Park is downwind from large urban and industrial areas in states to the south and west. Periodically, high concentrations of air pollutants blow into the park from these areas. Learn more about air quality and monitoring throughout the park.
Climate change refers to changes in the Earth's long-term weather patterns. Some changes in climate occur naturally; gradual temperature fluctuations over thousands of years are a natural part of the Earth's climate. The Ice Age, for example, was a period of time when our climate was much cooler than it is now. However, human activities can also cause changes;the term "climate change" is generally used to describe a more rapid, human-caused increase in the Earth's average temperature.
Research on fire occurrence in Acadia National Park indicates that large, naturally caused fires are not as common as in many of the western parks. The cool, humid, coastal climate and low occurrence of natural ignition sources such as lightning makes these fires relatively rare.

Pests are those species that interfere with the purposes of the park such as protecting natural or cultural resources, or visitor safety. For example, carpenter ants threaten the structural integrity of park buildings. Raccoons and red foxes can carry rabies and quickly learn to aggressively scavenge food scraps from campers and other visitors. Non-native diseases such as beech bark disease and white pine blister rust kill trees, and can change the structure, composition, and functions of forests in Acadia.

The National Park Service uses Integrated Pest Management (IPM) to manage pests. This approach is based on proper identification of a pest and a thorough understanding of the biology of the pest species being managed.
Both the motor road system and the (non-motorized) carriage road system at the park were carefully laid out by prominent landscape architects to take advantage of these spectacular views. Although they are dependent on the natural landscape of Acadia, these designed landscapes have themselves become significant, owing to their history and the sensitivity with which they were designed and built. In recent years, park staff have been actively restoring historic vistas on the carriage road system. Click here to learn more about our current vista management project.
Integral to ecosystem health and function, the waters of Acadia also allow visitors to engage in a variety of recreational pursuits. Protection of the scientific and scenic attributes associated with Acadia's lakes, streams and wetlands, and their use as a source of public drinking water, were significant factors in the park's establishment. Water resources within or adjacent to Acadia include 14 Great Ponds, 10 smaller ponds, more than two dozen named streams and 10 named wetland areas.
