Tree Martin Nest Survey in Power Poles 2024-2025

BirdLife/Wirambi Landcare Tree Martin Survey recorded 33 Tree Martin nests over a five-month period from September 2024 to January 2025. Vehicle-based surveys identified that 30 nests were located in the cross bars of street power poles. The data describes nest proximity to native vegetation, urban parkland, and wetlands.

Use Cases

• Analyze nest location preference by correlating nest sites with proximity to wetland and remnant native vegetation features.
• Model habitat suitability for Tree Martins using variables like distance to wetland and surrounding land cover type (parkland vs. vegetation).
• Assess urban ecology impacts by studying the concentration of nests in street power pole cross bars versus other structures.

Strengths

• Data collection occurred over a defined five-month period from September 2024 to January 2025.
• Survey provides specific quantitative findings: 33 total nests, with 30 (91%) located in power pole cross bars.
• Includes detailed environmental context percentages: 52% of nests near native vegetation, 48% within 500m of a wetland.

Limitations

• Small sample size of only 33 observed nests limits statistical power for detailed analysis.
• Survey method (vehicle-based) may introduce geographic bias, missing nests outside surveyed routes.
• Unknown column structure and lack of raw sample data restricts immediate analytical use.
