Daily observations of mammals from the Toolik Naturalist Journal, Toolik Field Station, Alaska, 2006-2023

The Toolik Field Station - Naturalist Journal is a daily collection of observations of weather,wildlife, and phenological characteristics around the Toolik Lake region. The mammal records are from as far south as Travis creek (50 kilometers (km) south of Toolik on the Dalton Highway) to as far north as Ice cut (~65 km north of Toolik on the Dalton Highway). Mammals are recorded if they are seen, if fresh tracks are seen, or if in the daily comments there is a record of an animal being heard. Mammals are not specifically searched for on a daily basis, all observations are happenstance. During the months of May-September observations are made daily along the Dalton Highway. From October to April, observations are most often limited to the area directly around Toolik Field Station out to Imnaviat Creek (~5 km from Toolik Field Station).
