* Activity indices were assigned to 3 activity categories based on trap success and/or camera data with the highest quartile designated as “Very Common”, all remaining sites in which the species was detected, as “Present”, and failure to detect: “Rare/Absent”.
**As Blarina have been observed to vary greatly in abundance, we chose to assign each fragment to one of 5 activity categories based on catch per unit effort.
