在1970年至1971年冬季的四个时期内,在温哥华岛的北部和西部海岸进行的空中计数表明,1980多只海狮总共使用了15个撤离区。有证据表明,许多冬季运输地区往往在夏季被遗弃。
Aerial counts conducted on the north and west coasts of Vancouver Island during four periods in the 1970–71 winter indicated that more than 1980 sea lions used a total of 15 haul-out areas. Evidence is presented indicating that many winter haul-out areas are often deserted in summer.
