For park rangers, game wardens & conservation officersFree · no signup · nothing tracked

First on scene is the job description.

Rangers, wardens, conservation officers — different patches, same math: solo patrol, big country, and every visitor emergency lands on you first. Until backup makes the trailhead, the officer is also the medic. This is the medicine for that stretch of the call, free.

Your version of a bad day

Start here

All 15 lessons are worth your time, but this order front-loads what your world serves up:

  1. Patient Assessmentthe first-on-scene system, run alone until backup
  2. Medical Emergenciesthe visitor cardiac — denial, aspirin, and early help
  3. Heat Illnesstrailhead to heat stroke, and the cool-first doctrine
  4. Bites & Stingssnake calls without the folklore
  5. Evacuationsizing an incident when you are the resources

Then pressure-test it

Interactive scenarios — one decision at a time, tempting mistakes included, debrief at the end:

The certification question, honestly. “Wilderness First Aid” isn’t a regulated credential. No government body defines what a WFA card means — it means whatever the company that printed it says it means. What counts in front of a patient is whether you can do the work. This course teaches the work, free, and issues a record of completion — not a certificate, and we won’t pretend otherwise. Agency training requirements — academy medical blocks, in-service standards, whatever your department mandates — stand untouched. This is prep before the academy and fluency between in-services, not a line on a training record. If nobody requires you to hold a card, what you need are the skills, not the laminate.

What this is

Fifteen lessons, a 40-question knowledge check, sixteen practice scenarios, a printable field reference card, and a kit checklist. Free, no account, nothing recorded about you, source on GitHub. It teaches decision-making, not hands-on skill — practice the hands-on parts on a real, padded, complaining friend.
