Data Release Reports (DRR) are created by the National Park Service and provide detailed descriptions of valuable research datasets in a human-readable format, including the methods used to collect the data and technical analyses supporting the quality of the measurements. DRRs focus on helping others reuse data rather than presenting results, testing hypotheses, or presenting new interpretations and in-depth analyses. The National Park Service's San Francisco Bay Area Network (SFAN) and partners began regular long-term monitoring in 1999 after conducting inventories in 1997 and 1998. After network QA/QC, the data were processed by the Inventory and Monitoring Division (IMD) to comply with Executive Order 13642 (Making Open and Machine Readable the New Default for Government Information). One data cleaning script was produced, resulting in four datasets: AnnualBreedingStatus, EventSurvey, NestTreeSurvey and SpeciesDetection. The script was used to format the data for clarity and consistency, and to generate cleaned CSV files for the associated data package. This DRR describes the data package for a monitoring protocol of northern spotted owl surveys conducted in Golden Gate National Recreation Area, Muir Woods National Monument, Point Reyes National Seashore and the surrounding areas from 1998-2025, including how and where to access the data, collection methods, processing steps, data quality evaluation, and usage notes. The Data Package this DRR refers to is: Ellis TD, Ron A, and Sherrill KR, Edson EM. 2025.
