Managing a wildlife crime scene demands the same rigour as any homicide investigation but in terrain that is hostile, remote, and often legally cross-jurisdictional. This topic covers scene categories, GPS-anchored documentation, first-responder protocols, and the photographic standards that keep evidence court-ready from the bush to the courtroom.

A poached elephant does not die at the edge of a car park. It dies at the end of a week-long trek into terrain that may be forty kilometres from the nearest road, in heat that accelerates decomposition, and surrounded by scavengers whose own activity starts destroying trace evidence within hours. By the time rangers reach the carcass, the kill site is already changing. How an investigator manages the next two hours often decides whether a prosecution succeeds or collapses.
Wildlife crime scene management borrows its core logic directly from homicide investigation: secure the scene, document before touching, work from outer to inner, maintain an unbroken chain of custody. What it adds is a set of field-specific adaptations: GPS in place of fixed reference points, photographic protocols calibrated to grass and mud rather than linoleum, and evidence timelines shaped by tropical biology rather than indoor preservation. The scene categories are also broader. A kill site is only one type. A live-animal seizure at an airport cargo shed, a carcass dump hidden in secondary forest, and a transit container packed with dried seahorses each require a different evidence priority list and a different sense of urgency.
This topic maps the four main scene categories, explains the first-responder protocol that applies to all of them, and walks through the photographic and GPS documentation standards that can transform field notes into court-admissible records. It closes with the jurisdictional tangle that defines many wildlife cases, where the kill, the processing, and the export happen in three different legal systems and evidence must survive the journey between them.
The evidence you look for first depends entirely on the type of scene you have walked into.
Not all wildlife crime scenes look alike, and treating them as if they do costs time and evidence. The four main categories each have a distinct evidence hierarchy, a different decay clock, and different contamination risks.
Wilderness is not a laboratory, and the gap between the two has swallowed more than a few prosecutions.
Urban crime scenes benefit from infrastructure: roads for rapid attendance, electricity for lighting, nearby refrigeration, and evidence submission times measured in minutes. Remote wildlife scenes offer none of these. An investigator who reaches a kill site in a national park may have hiked for five hours in temperatures above 35°C, arrived after dark, and has no prospect of lab facilities for three days. Every protocol must be adapted to function under those conditions.
A photograph without a coordinate is a picture; a photograph with a coordinate is evidence.
GPS changed wildlife crime scene documentation more than any other single technology. Before it, scene sketches relied on distances measured by tape or pacing from a fixed natural landmark that might not survive the growing season. A coordinate recorded with a consumer GPS or a smartphone is repeatable to within a few metres by anyone, anywhere, years later. That reproducibility is what makes it valuable in court.
Modern drone survey supplements GPS point data. A flight over a kill site produces an orthophoto mosaic that shows the spatial relationship between tracks, drag marks, and the carcass at a glance. Southern African anti-poaching units have used drone imagery as prosecution exhibits to show that footprints found near a carcass were consistent with a specific approach route, placing suspects physically at the scene.
Overall, mid-range, close-up: the three-tier discipline that turns field photography into evidence photography.
SWGMAT guidelines for scene photography were written for indoor forensic contexts but their three-tier structure translates directly to the field. The logic is spatial: overall shots establish context, mid-range shots orient an exhibit within its immediate surroundings, and close-ups capture the detail that makes comparison possible. Every close-up must include a scale item.
| Tier | Purpose | Field execution |
|---|---|---|
| Overall | Establish scene context and boundaries | Wide-angle from the highest available vantage point or drone; cover all cardinal directions |
| Mid-range | Orient each exhibit within the scene | Photograph from 1-3 m showing the item and its surroundings; include a numbered marker |
| Close-up (with scale) | Capture detail for comparison | Fill the frame with the item plus a metric scale rule; use flash or reflector to eliminate shadow |
| Close-up (without scale) | Show detail in natural context before scale is placed | Shoot once before placing the scale, then again with scale in position |
Wildlife-specific additions sit on top of this standard framework. Wound channels require both external photographs and, after necropsy, internal views showing projectile path and tissue damage. Track patterns are photographed as a set (the whole trackway) before individual impressions are documented. Snare injuries on a carcass are photographed under raking light to show groove depth. Collar antenna trajectory and position on a GPS-monitored animal are documented before the collar is removed, because the direction the animal was travelling when it died can reconstruct whether it was moving toward or away from a threat.
The first officer at the scene sets the ceiling for what the whole investigation can achieve.
First-responder protocol at a wildlife scene follows the same stop-look-record-cordon sequence familiar from other crime scene types, but adapted for terrain where other responders may be far away and the first person present is often a ranger rather than a scenes-of-crime officer. The protocol must work as a checklist rather than as a set of guidelines that require expert judgement at each step.
Wildlife crime routinely crosses borders; the chain of custody must cross them too.
Wildlife trafficking is one of the most geographically dispersed crime types. An ivory consignment may originate with a poaching event in Tanzania, pass through Mozambique for processing, be loaded at Dar es Salaam, transit through Hong Kong, and arrive as carved artefacts in Vietnam. Each country has its own laws, its own chain-of-custody requirements, and its own definition of what constitutes admissible evidence. An exhibit that was properly handled in Tanzania may be ruled inadmissible in a Vietnamese court if it was not documented in a form the Vietnamese system recognises.
Effective management in multi-jurisdiction cases requires advance agreement on lead-agency authority, a common evidence numbering system, and documentation in a format that satisfies the highest-standard jurisdiction in the chain. UNODC guidelines and the INTERPOL Wildlife Crime Working Group have developed joint-investigation protocols specifically to address these gaps. Where a ranger does not have police powers, a memorandum of understanding with the national police service should define exactly which agency seizes exhibits, who signs the chain-of-custody forms, and who holds the master exhibit register.
A poaching scene at which the ivory has been removed and the carcass hidden in secondary forest some distance from where the animal died is best classified as which type of wildlife crime scene?
