Aesthetic and Other Applications

The LTRR recognizes that its extensive and diverse collections may have applications beyond their analytical contributions to dendrochronology and related sciences. Specifically, aesthetic, artistic, interpretive, and public awareness applications are encouraged.

General Information
All requests must be submitted at least one month in advance, preferably earlier.

Current LTRR PIs may use or provide access to their active research collections at their own discretion. Current PIs will not be denied access to Archived samples they have collected.

No research specialist, research associate, technician, student, visiting scholar or post-doctoral researcher may authorize or independently provide access to any sample(s) at the LTRR for such applications. Prior written approval from the LTRR Director, advisor/Host and/or the Curator (as applicable) is required to use any sample(s) collected withsignificant use of university resources.

For non-LTRR affiliated requests: should the application require a significant amount of time or other LTRR resources the requestor may be asked to compensate the LTRR. If required, any compensation will be negotiated on a case-by-case basis and must be received prior to beginning the project.

Procedures (choose one):
A   Requests for access to active research collections

All requests for access to active research specimens must be directed to the current LTRR PI who funded, collected and maintains the samples. Approval for access to active research collections is at the discretion of the PI; however, the PI should communicate with other pertinent LTRR personnel to ascertain if the request will conflict with internal research or other priorities. In the case of multiple PIs, a decision must be reached among the group. Applicants should submit a request directly to the appropriate PI, with a copy sent directly to the Curator.

B    Requests for access to a portion of the Archives

All requests for work with the Archives must be directed to the Curator. Requests will be vetted by the Curator and credentials will be confirmed. For applicants who are not well established, please attach a brief CV.

NOTE: Many specimens curated by the LTRR are the property of government agencies. It is the responsibility of the applicant to arrange permission with the appropriate authorities and forward this information to the Curator. No work will be permitted until the Curator has confirmed agency approval, when necessary.

Due to the highly individualized nature of these requests, each project will be negotiated on a case-by-case basis.

Mandatory conditions:
1) No provenience information will be provided. If any information is incidentally obtained (i.e. by photographing labels, boxes, etc.) it may not be included in the presentation of the specimens.

2) The LTRR is provided with digital copies of all of the images or product of the work for our unrestricted educational use (standard citations will be included when appropriate)

3) Archived tree-ring specimens may be used as approved by the Curator or Director, specifically excluding: samples currently being investigated by a faculty member or other researchers with the LTRR, and any archived material to which current PIs specifically object.

4) The "Laboratory of Tree-Ring Research at the University of Arizona" should be acknowledged in a prominent location. This should be done as is standard practice for the style of the product.

5) A disclaimer is included in a prominent enough location of adequate size that states "Any opinions expressed or interpretations derived from [title of Exhibit/work] do not necessarily reflect the views and opinions of the Laboratory of Tree-Ring Research or its personnel. The LTRR is a research unit in the College of Science at the University of Arizona and does not endorse or support any political, religious or social agenda." The disclaimer should not impede on the viewing experience of the work, but it must be accessible to all who view it.

6) Any work that will result in direct financial gain may be subject to additional fees or restrictions (i.e. if post-card or calendars are made for sale to the public, other arrangements must be agreed upon with the Director or Curator, prior to any such occurrence--permission for such purposes is not guaranteed or implied in any way).

7) All necessary equipment must be provided at the requestor’s own expense.

8) The LTRR takes no responsibility nor makes any guarantees for any equipment used during the project, nor for its safety, shipping, operating conditions, etc.

9) All costs of the work and preparation thereof are to be borne solely by the requestor (including but not limited to: airfare, housing, food, parking, film, etc.)

10) The LTRR must be notified of the location(s), time(s) and estimated total attendance of any exhibition of the resulting work and forward a copy of any exhibit related materials (brochures, etc.) to the Curator, for our records.

11) After the/an exhibit has finished showing at its scheduled venues, the work should be made available for display by the LTRR, at our discretion and at no cost.

12) No specimen(s) or associated material may be removed, whatsoever.

13) Any other conditions specifically noted.


Should any of the above policies be circumvented, abused or violated the individual, sponsor, and/or affiliated organizations may be barred from any further loans, samples, or use of the LTRR Collections.

As the LTRR hopes to encourage greater use of our Archives for legitimate purposes, fees may be negotiable at the discretion of the Curator and/or Director. Please contact us about alternative arrangements as early as possible.
