Research in the Park
Denali is a laboratory for research on many topics from A to Z (air quality to zoology). Each year, resource staff discover new findings about the plants, animals, and ecosystems of the park through short-term or long-term inventory, monitoring, and research projects. Other researchers from near and far submit proposals to conduct studies in the park. These projects are reviewed for their suitability for a national park. Whether you are curious to learn about the results of research about the park's creatures and ecosystems or are a prospective researcher wanting more information, there are extensive resources available: basic information on how to conduct research, a variety of information about natural resources and research results, or a quick look at many research results through a series of more than 60 nature and science fact sheets.
Biological Science - Wildlife, Plants, and More
Denali has a diversity of wildlife, that includes 39 documented species of mammals, 169 species of birds, 14 species of fish, and one species of amphibian. Learn more about wildlife in Denali.
You can't view the slopes and valleys of Denali without being introduced to some of the more than 650 species of flowering plants that collectively create the vegetation of the park. These plants provide cover and food for many animals. Only plants adapted to long, cold winters and short growing seasons can survive in this subarctic wilderness. Learn more about plants in Denali.
