Hermit Warbler Occupancy Dynamics In Sierra Nevada Forests

Luca Bielski's 2026 figshare dataset analyzes Hermit Warbler population responses to climate and wildfire. The study, using a four-year passive acoustic monitoring program, recorded an 8.3% population decline. It models occupancy dynamics in response to elevation, latitude, temperature, and high-severity fire.

Use Cases

• Model species extinction probability using the high-severity fire response variable over a 1-10-year post-fire period.
• Analyze population shift patterns by correlating occupancy changes with elevation and latitude data.
• Forecast future habitat suitability by integrating the relative temperature and severe fire response parameters.

Strengths

• Data underpins a published ecological study quantifying an 8.3% population decline.
• Analysis is based on a four-year, landscape-scale passive acoustic monitoring program.
• Explicitly models responses to key environmental drivers: elevation, latitude, temperature, and fire.

Limitations

• Dataset is very small at 12.0 KB, indicating limited raw data or highly aggregated summary statistics.
• Unknown row and column structure prevents assessment of sample size or feature granularity.
• Temporal coverage is limited to a specific four-year study period, not long-term.
