Miles of unspoiled beaches are a third prominent feature of the park. The scientific features of the national lakeshore extend far beyond the visually spectacular. Because of its location within the transition zone between the boreal and eastern deciduous forest biomes, Pictured Rocks has elements of both forest types. Hardwood forests of maple and beech are prevalent, but conifers dominate some sites. Soils range from well-drained sandy soils to hydric soils. Streams, ponds, marshes, bogs, and other aquatic habitats are abundant. Lake Superior wields a powerful climatic force over the region; by keeping adjacent lands warmer in winter and cooler in summer, it greatly influences physical conditions that impact the park's plant and animal communities. ![]() AnimalsWildlife in this varied landscape includes white-tailed deer, black bear, tree frogs, many types of birds, and an occasional moose. ![]() PlantsPictured Rocks National Lakeshore abounds with diverse and healthy plant communities. ![]() Environmental FactorsWeather, climate, water quality, and invasive species are some of the environmental factors impacting Pictured Rocks National Lakeshore. ![]() Natural Features & EcosystemsPark lands include sandstone cliffs, perched sand dunes, forests, beaches, wetlands, inland lakes, and many other natural features.
Along with university researchers and other partners, the national lakeshore's Science and Resource Stewardship Division conducts studies on resource management issues involving wildlife, water quality, invasive species, forest health, and many other topics. Much of the scientific research conducted in the park is done in cooperation with the NPS Great Lakes Inventory and Monitoring Network, which coordinates research and science projects for all the national park units in the Great Lakes. |
