Using this information, we buffered the 24-hour occupancy locations listed above by 1.6 km 1 mi and calculated an overall search area for both the coastal and inland zones. The coastal
and inland occupancy buffer shapefiles were then used to select encounter records that were associated with 24hour occupancy locations, resulting in the number of bears encountered per
zone. These numbers were then separated into open-water and ice seasons Table 2.
