## What is Picket Line?

Picket Line is for the people who see an animal wound first: ranch hands, producers, hunters, 4-H families and veterinarians.

Photograph a wound, a larva or a fly, answer a few questions about what you see, and get a triage in under a minute with the cues behind it. If it is Likely or Possible, one tap opens or dials the official channel for your state and USDA APHIS with a prefilled report.

• Cue-based triage: see exactly which signs drove the call.
• One-tap handoff to USDA APHIS and state animal health officials (Texas, Florida and New Mexico to start).
• Your reports stay on your phone and queue when you are offline.
• With your consent, a location rounded to about 1 km joins a public activity map alongside Picket Line's autonomous trap nodes.
• Node tab: field crews can set up a Picket Line trap node over Bluetooth.
• No account required. No ads, no tracking.

Picket Line gives a triage, not a diagnosis. It never replaces the official report, and nothing in it should delay veterinary care. Confirmed cases are published only by USDA APHIS and state animal health officials.
