Taxidermy and natural history specimen collection have deep scientific value but involve welfare considerations in the collection and preparation of animals for preservation.
Specimen collection welfare has improved dramatically as natural history collections have shifted toward opportunistic collection of already-deceased animals rather than lethal collection of live animals. Modern scientific collection protocols require ethical justification and prefer minimally invasive methods. The welfare case for historical natural history collections — which were often conducted with minimal welfare consideration — is moot, but those specimens continue to provide scientific value. Contemporary collectors and taxidermists who source from road kill, zoonotic monitoring programs, and naturally deceased animals produce specimens without additional animal welfare cost.
