Unrecognised DNA Degradation in Flash‐Frozen Genetic Samples in Natural History Collections Optimal preservation of tissues from the field to long-term cryo-storage is paramount to securing genetic resources for research needs. DNA preservation techniques vary, with flash freezing currently...

Flash-frozen tissues are considered the gold standard for DNA—but our analysis of field-collected samples found surprising degradation.
Preserving in buffer before freezing may be more robust in real-world conditions.
