Destructive Sampling Policy
Permission may be granted to sample material from MICH collections on a case-by-case basis. We recognize the usefulness of selected herbarium specimens as the source of morphological material (pollen, spores, seeds, etc.), for DNA, or other purposes. Because preservation of the value of the specimen for morphological examination is also one of our primary objectives, the following guidelines must be followed when using MICH material for DNA extraction. Destructive sampling will be most favorably considered for recent specimens that have an ample amount of the desired material.
Sampling from type specimens and historical collections is not permitted unless authorized by written permission from a member of the MICH curatorial staff.
Specimens may be sampled only for scientific study, not for commercial purposes.
Permission will not be granted if the collection is rare, or too small to allow the loss of any material.
For specimens mounted on sheets, please use material in the packet on the sheet, if available, and, if taking small samples from intact leaves, please take the material in such a way as to not compromise future leaf shape and size measurements (i.e., do not clip off tips, bases, auricles, etc.).
Specimens used in destructive sampling studies must be annotated. The annotation slip should include the type of material removed, date of removal, and the person responsible for the sampling. For DNA extractions, the GenBank accession number should be provided to MICH and cited in any resulting publication.
Please consult MICH with any questions about this policy or about suitability of individual specimens.
While it is our intention to provide accurate information, our data is compiled from the information collectors provide on their labels. The accuracy of label information is a reflection of the knowledge and expertise of the individual collector.
