Burrowing petrels at Heard Island, 1987/88.

Surveys were conducted at the eastern and western ends of Heard Island during the 1987/1988 season. Burrow densities in different habitat types (vegetated and unvegetated) were determined from fixed width transects. Extensive areas at both ends of the island were surveyed and detailed information was obtained on distribution and abundance on 4 species of burrowing petrels.This work was completed as part of ASAC project 451 (ASAC_451).This work also falls under the umbrella project, ASAC 1219 (ASAC_1219).

1987/1988调查季，研究人员于赫德岛（Heard Island）东西两端开展野外调查。采用固定宽度样带法，测定了不同生境类型（植被覆盖区与无植被覆盖区）的洞穴密度。对该岛两端的大片区域进行了全面普查，获取了4种穴居海燕（burrowing petrels）的分布与种群丰度的详细数据。本研究系南极科学咨询委员会（Antarctic Science Advisory Committee, ASAC）项目451（ASAC_451）的组成部分，同时隶属于总项目ASAC 1219（ASAC_1219）。
