Surveys from the 1987/1988 season document the distribution and abundance of four burrowing petrel species at Heard Island. The Australian Antarctic Data Centre (AU_AADC) collected this data through fixed-width transects across vegetated and unvegetated habitats at the island's eastern and western ends. This work was part of ASAC projects 451 and 1219.
Use Cases
- Model burrow density as a function of habitat_type (vegetated vs. unvegetated) using geospatial transect data.
- Compare species_abundance distributions for the four petrel species across the eastern and western survey areas.
- Analyze spatial distribution patterns of burrows from transect data to identify key breeding habitats.
Strengths
- Data covers extensive survey areas at both the eastern and western ends of Heard Island.
- Includes detailed information on distribution and abundance for four distinct petrel species.
Limitations
- Specific sample sizes, row counts, and measurement scales for transects are not provided.
- Data is from a single season (1987/1988), limiting analysis of temporal trends.
