So it looks like you have a nice little population of Franklin's out
I've caught 10 individual in a day and a half. There are burrows all along the grassy strip to the right of the lane as well as by the garbage pile and tree clumps in the prairie area. Unfortunately the dogs got to one of the traps today and killed a squirrel so I'll be moving the ones that are closer to the house elsewhere tomorrow. Let me know if you want to come out and check traps with me sometime. I'll be checking them thursday around 12:00 and 5:00, and then friday at 12:00 again when I'll also pick them all up.
By the way, would you happen to have a list of plant species that are in the prairie? Maybe a seed list from when it was planted?
