       | track samples, and the single snow leopard sampled
       | 
       | Samples of snow tracks taken were not large, mostly <500ml up to
       | just over 2100ml.

       | Snow is probably an ideal medium to store eDNA, and clear tracks
       | would indicate freshness.
       | 
       | From reading the paper they were trying to show that collecting
       | eDNA from snow tracks can work, rather than that classification
       | of unknown random individuals can work from just sampling tracks.

       | Ark, Sweden in 2021 using fresh snow brought in from a nearby
       | forest. Nasal mucus was collected from the same individual as a
       | positive control.

       | The cat must have been quite confused as to why they dumped a
       | bunch of snow in its pen!
