DISC is an early-stage research concept from SAFE, exploring whether the colour of a rescue halo affects a koala’s stress during a canopy retrieval. It’s a question worth answering properly — with the right institutional partners and full ethics approval.
DISC — Dichromatic Interpretation and Stress Calibration in Koala Retrieval — sets out a simple but untested question. Koalas see colour differently to us, so does the colour of the halo we raise toward them change how calm or stressed they are during a rescue? If it does, we can design halos that make an already-approved method gentler still.
Koalas are dichromatic — their colour vision is not like ours. A colour that reads as “soft” to a person may not read the same way to a koala.
Behavioural and physiological cues give a read on an animal’s stress. Calibrating halo colour against those cues is the “stress calibration” in DISC.
The halo method is already approved. This is about refining the tool so the calmest possible rescue becomes the default, not the exception.
To be clear: DISC is at the concept stage. No animals are involved, and none would be unless and until the work is designed and run by an AEC-approved institutional partner, under a formal Animal Ethics Committee protocol. SAFE’s role is to pose the question, bring the field equipment and rescue experience, and support a research team set up to answer it rigorously and humanely.
We would like to connect with universities, research institutes and wildlife-health teams with animal-ethics oversight — particularly anyone working in animal vision, koala health, or welfare science — who might be interested in shaping and running a study.
Universities and institutes with an Animal Ethics Committee and a pathway to approval.
Researchers who study how animals perceive colour and contrast.
Clinicians and welfare researchers working hands-on with koalas.
If your institution could partner on DISC — or you know who should — register your interest and we’ll follow up with the concept brief and the ethics pathway.
