The University of Arizona

Curation and Preservation Fund

The LTRR is dedicated to provide the highest standard of preservation for the specimens and records in its care. However, for nearly a century the financial onus has rested completely on the LTRR and by extension its faculty and staff, the University of Arizona, the State of Arizona, and occasionally gracious private citizens. Due to the rapid growth of the Collection, and the field of dendrochronology, this is no longer a viable option. Nor should it be responsibility of the above entities alone to provide for the care of specimens which are of crucial importance to the entire scientific community, collected from diverse geographic and governmental districts.

Accordingly, the LTRR has established a “Curation and Preservation Fund.” All monies deposited in or earmarked for the Fund will be used solely for the purpose of maintaining the LTRR’s extensive Collection, providing the highest level of care, and directly related costs.


Donations are welcomed, and may be tax-deductible!

Of the LTRR’s Collection, H.J. Arnott, Professor Emeritus of Biology at the University of Texas at Arlington, has accurately concluded:

“…the LTRR is a National Treasure…especially in terms of its collections. There are collections [here] that cannot be made again as the material no longer exists in nature…that are one of a kind; the opportunity to collect them again is gone…that illuminate the development of dendrochronology from its inception” (Texas Journal of Microscopy, 38.2: 23).

Since most of the specimens at the LTRR cannot be collected again, it is imperative that they be preserved as long as possible at the highest standard. Many specimens are vouchers for important scientific advances and must be available in perpetuity for future research or reinterpretation.


LTRR PIs are asked to budget for curation and preservation in grant proposals that will result in the growth of the Collection (including specimens, electronic files, field notes, etc.). PIs should budget for U.S. $250 per cubic foot of material that will, eventually, be archived. If large volumes of electronic data will be produced, it too should be preserved, please budget accordingly. If the grant application is successful, these funds will be earmarked for curation expenses and should not be viewed by the PI as contingency funds or surplus for the proposed research. Please consult the Curator if you have any questions or require assistance.

Remember: “Budgets for development projects or academic research are remiss unless there is a line item for curation. Without curation…collections are lost.”

(San Diego Archaeological Center, Collection Guidelines, February 2009: 6)

For External Organizations, Institutions and Individuals:

The LTRR has traditionally served as a repository for all kinds of dendrochronological specimens: archaeological, remnant, etc., and will continue to for the foreseeable future. To assist with the curation and preservation of materials accessioned or received by loan agreement into the LTRR collections, some fees must be instituted. Without these nominal fees, the LTRR will be financially prohibited from continuing these services.

NOTE TO RETIRING SCHOLARS: If you have a collection of dendrochronological material and no viable option for ensuring its future curation, please contact the Curator or Director. The LTRR may be able to assist with this process.

Often, the LTRR has been the last refuge for abandoned or orphaned collections, as few other institutions are both capable and willing to assume the long-term responsibility. Please contact the Curator or Director for further information. While the LTRR makes no guarantees to accession any orphaned collection, the Fund may be able to ensure that these valuable and irreplaceable specimens are preserved and made available for future research.


  • All fees stated above will be deposited or reserved for the Curation and Preservation Fund.



  • A University Administrative Service Charge (ASC) may apply. Where applicable, the ASC is ADDITIONAL to any fees. 



  • All accessions/loans are different and must be individually addressed PRIOR to the arrival of specimens at the LTRR.



  • Accessions and loans take time to arrange, please contact the Curator as soon as possible if considering either. At least one month in advance is ideal, but a minimum of two weeks is required.



  • Please direct all inquires and communications regarding collections to the Curator.




Individuals, institutions and organizations are also encouraged to make donations to the Fund. Please contact the LTRR Business Manager or Curator for further instructions, as these donations may be tax-deductible.
