@heidi.h Definitely a valid question. It looks like they have it connected to a zooniverse project, which means they are using citizen science to not only set up and maintain the cameras, but to process the data. Pretty neat. 

What we do

Our main task is to get our trail camera volunteers up and running with equipment and training. Volunteers can now apply to host a camera in Wisconsin survey blocks where they have access to land (visit dnr.wi.gov, keyword "Snapshot Wisconsin" for more information). Trail camera volunteers are in charge of setting up a camera and retrieving its SD card (containing saved photos) at least four times per year. Volunteers then send the photos to WDNR to be posted on Zooniverse. By the end of 2017, we expect to have enough cameras for > 2000 volunteers to participate in the project -- these cameras will produce millions of photos each year!

While we get our trail camera volunteers set up, we have plenty of other photos to show the Zooniverse community. WDNR staff have placed over 300 trail cameras in two areas of the state now home to a species of elk (Cervus elaphus) formerly abundant throughout North America. Elk were extirpated from Wisconsin in the 1800s due to overhunting and habitat loss. Reintroduction efforts began in 1995 and continue today, and we're curious to know how the elk are doing! Classifying the photos from the elk reintroduction areas will give us great information about population size and distribution, and examine how elk presence overlaps with that of wolves--natural predators of elk.
