📱 iNaturalist Integration

Best Practice: Every observation should have 3 photos: Whole organism, Habitat context, Diagnostic features. Enable high accuracy GPS.

📸

Photo Protocol

• Whole plant/animal in frame
• Close-up of leaves/flowers/bark
• Habitat background
• Scale object (coin/ruler)

Metadata Checklist

• Date & Time (auto)
• Location (GPS <10m accuracy)
• Wild vs. Captive/Cultivated
• Notes: "Quadrat Q1, n=15"
