Isle Royale National Park Vegetation Change Analysis 1996 to 2017 - Randomly Selected Sites

Vegetation change is an important issue facing managers at Isle Royale National Park (ISRO). These data were created using high-resolution imagery collected in the winter of 2017 which was compared to the vegetation map of the National Park published in 2000 (project imagery collected in 1994 and 1996). These data review where vegetation cover type, density, and pattern have changed since imagery collection for the 2000 publication and provide a proposed reason for the change.

Isle Royal National Park (ISRO): Initial Forest Communities of Isle Royale National Park

This data set represents initial forest communities developed for Isle Royale National Park. LANDIS-II requires an input data layer that contains the ages of each species cohort present within each cell of the landscape. To develop this layer, we matched the composition of forest inventory plots to a map of forest types, and randomly imputed U.S. Department of Agriculture Forest Inventory plots within each matching forest type

Burn Severity Assessment of the 2021 Horne Fire at Isle Royale National Park

The 2021 Horne Fire on Isle Royale National Park (ISRO) ignited when lightning struck the island near Duncan Bay on August 10, 2021, during elevated drought conditions. Per the National Park Service, it would continue to burn slowly and spread until a wind event on August 21, 2021 caused significant spread and initiated a control effort to protect historical structures in Tobin Harbor. The fire was 75% contained by September 6, 2021, and allowed to smolder until winter rain and snow finally extinguished the fire. The Horne Fire became the third-largest wildfire in the park’s history, necessitating a detailed assessment of landscape responses to spatial variability in burn severity. These data were created by comparing...

Characteristic textures of volcanic rocks On Isle Royale. Isle Royale National Park, Keweenaw County, Michigan. 1971.

Isle Royale National Park, Michigan. Characteristic textures of volcanic rocks On Isle Royale: pegmatite from the differentiated zone of the Greenstone Flow on the east end of Passage Island. This rock has a texture in which all of the minerals, especially the plagioclase, are larger when compared with those in most of the other rock types; the elongate plagioclase laths give the rock a matted appearance. Circa 1971. Figure 4-E, U.S. Geological Survey Professional paper 754-C; Figure 12-E, U.S. Geological Survey Bulletin 1309.
