Sean Pattrick is an instructor at both EcoTraining and Counter Insurgency Tracker Training (CITT). He uses his years of tracking experience to teach and train others how to track animals and humans. At EcoTraining, he teaches students how to identify the kind of animal, size, weight, gender, which direction it is headed and the approximate number. When at CITT, Sean trains anti-poaching rangers what to look for so rangers won't be fooled by tricks poachers employ to keep from being followed or captured. In either setting, he points out how the tiniest mark in the soil or broken branch could cause someone to unwittingly walk into a pride of lions or a gang of armed poachers.
