Just a reminder about tonight’s Global City presentation Tuesday, March 5th, 6:00-7:00 pm in the U. J. Noblet Forestry Building G002, Michigan Tech (please note the room change for our regular members!). We welcome Isle Royale National Park employees Seth DePasqual (Cultural Resource Manager), Mark Romanski (Biological Science Technician) and Lucas Westcott, (West District Interpreter) to give the following presentation:
Of Marten and Men:
Implications of Spatial Analysis in Cultural and Natural Resource Research at Isle Royale National Park
Over its history, the isolation of Isle Royale has made it a premiere location for research on cultural and natural history. A variety of spatial analysis technologies are helping current National Park Service researchers examine diverse park resources in new ways. Come join NPS staff for a discussion about how spatial analysis is playing a role in research on Isle Royale’s genetically distinct pine marten population, as well helping identifying potential historic and prehistoric archeological sites. (For more detailed abstracts please see below.)
Pizza and pop provided, please bring your own mug to minimize waste!
Looking forward to seeing you there!

These efforts resulted in the location of many previously undiscovered site features including historic roads, prospect trenches, and diamond-drill coring stations. With regard to prehistoric features, archaeologists targeted the island’s relict shorelines as a means to site discovery.These features (including those not yet discovered) improve our understanding of significant island prehistories/histories and lend themselves to informed decisions regarding future management actions, public interpretation and the relevance of cultural resources in Wilderness.
Although traditional survey methods are sometimes adequate for discovery of these types of features, the time and personnel necessary are typically in short supply. LiDAR allows researchers to ballpark, if not pinpoint certain anomalies that are compatible with certain island cultural themes. Related methods streamline federal survey efforts allowing more time for actual site examination and documentation. Without LiDAR, a great deal of time and expense would be committed to searching for such features as opposed to documenting them.

Isle Royale National Park contains the only insular population of American marten in the contiguous United States. Marten at the park likely experienced a population and genetic bottleneck during the early 20th century and after a 60-year apparent absence, their presence has been reconfirmed. Investigations of genetic isolation and relative distribution suggest abundance of marten at the park is very low, approximate 30 individuals, and that this population is genetically distinct from its likely source population. There is considerable concern that the park could lose this rare population of forest mesocarnivores without further information to assess this population’s status. This situation is exacerbated as natural colonization from the mainland is virtually impossible. Given ISRO martens are likely their own genetically distinct subspecies, equivalent to the only other known subspecies of marten found on the island of Newfoundland, no known genetically similar source population exists if augmenting the population was warranted. As such, park researchers and their collaborators are conducting research designed to address the most salient aspects of this population’s natural history to help preserve this unique, insular population of marten.
