How this data was collected

Data Hunt Guide aggregates publicly available sighting reports from across the web — social media, hunting forums, harvest reports, and trail-camera shares — and uses a proprietary algorithm to identify high-activity zones (hotspots) within each unit. Our team verifies coordinates manually before publication. Unit 521’s 235 sightings represent 61 distinct hotspot clusters.
