Below are some of the current and recent projects the LTRR Curation team have been working on:
CSBR: Natural History Collections: Safeguarding the world's largest dendrochronological collection
National Science Foundation: $485,160
1st August 2018 - 31st July 2021
This project will safeguard the approximately 60,000 specimens that constitute the "modern studies" portion of the tree-ring collection, making them physically available, secure and electronically accessible via web resources. The specimens will be cataloged using the open source Tellervo software, which conforms to the Tree Ring Data Standard (TRiDaS) developed by the international research community. Tellervo will be further developed to include new curation interfaces to improve the efficiency of the cataloging workflow. To enable data to be provided to established biodiversity portals like iDigBio (iDigBio.org) and the Global Biodiversity Information Facility (GBIF.org), fields will be mapped from TRiDaS to the DarwinCore standard and delivered using GBIF's Integrated Publishing Toolkit (IPT). A dedicated web portal will also be developed for Tellervo enabling users to query the rich information associated with dendrochronological data beyond the core specimen collection information. Such information combined with full accessibility will enhance next generation studies in tree-ring science. The new curation, DarwinCore data export, and web portal tools developed during this project will be made available to numerous laboratories already using Tellervo, facilitating international adoption of a standardized procedure for collection, data and specimen storage for tree-ring research.
Service First: Increasing accountability of and public access to bureaus museum tree-ring specimens
Department of the Interior: $409,634
6th April 2-18 - 30th September 2020
The objectives of this project are to utilize developed protocols and templates, updated as necessary, to inventory bureau collections at LTRR, and enter information on an estimated 71,000 archeological and natural history specimens into a web-accessible catalog linked to centralized scientific data repositories and catalog the specimens into ICMS. Protocols for identifying and processing specimens will be evaluated jointly and refined continuously to improve efficiency.
Collections Stewardship: Rehousing, inventorying, and providing access to dendrochronological specimens in high risk storage
Institute of Museum and Library Services: $149,846
1st October 2016 - 30th September 2019
This project seeks to resolve the stewardship and access issues related to the portion of the collection that remains at highest risk of being forfeited as viable research and outreach materials. This subset of the collection is currently housed in an off-campus storage unit that lacks even basic environmental (e.g., temperature) and safety (e.g., fire suppression) controls. It is the last of the LTRR materials stored off campus and under such conditions.
Discover and make dendrochronology specimens accessible: Hawley-Bell Collection
National Park Service: $15,000
1st September 2016 - 30th September 2019
This project will continue the collaborative effort between the Laboratory of Tree‐ring Research and the National Park Service to integrate and catalog the archeological NPS specimens housed at the LTRR, but will focus primarily on identifying and integrating NPS dendro specimens from non‐Intermountain regions’ parks and monuments into the online searchable catalog of specimens maintained by LTRR and increase accountability for, and accessibility to, information about the specimens. Beyond the process of discovery for four ancillary sub‐collections at the LTRR, this project will focus on the cataloging of the Hawley‐Bell Collection, which is believed to contain NPS specimens from perhaps as many as 18 states, inside and outside the Desert Southwest. Some of these specimens may complement, and others may duplicate, collecting events that have already been identified in previous projects. Other collecting events and specimens may be entirely unique. Initially, a process of discovery will need to occur whereby documentation about the specimens and collecting events will need to be examined in order to understand the scope and breadth of the collections. Then, efforts will be focused on NPS‐owned specimens from collecting events from within NPS unit lands. The Hawley‐Bell collection will be the
primary focus of the cataloging effort, with an estimated 2,000‐5,000 specimens projected. Specimens from other collections will be undertaken as time permits.
Make dendrochronology specimens web accessible
National Park Service: $383,916
1st May 2014 - 30th April 2019
This project will continue efforts to integrate NPS archeological tree-ring specimens stored at the Laboratory of Tree-Ring Research (LTRR), University of Arizona, into a complete, on-line searchable catalog to increase accountability and public and researcher access. Students, in cooperation with staff of the Intermountain Region Museum Services Program, will identify legacy collecting events from NPS lands, and enter information on an estimated 62,000 archeological dendrochronological specimens into an existing data exchange format known as the Tree-Ring Standard for integration into a web-accessible catalog linked to the scientific data repositories International Tree-Ring Data Bank and/or the International Multi-Proxy Paleofire Database. The specimens also will be accessioned, cataloged, labeled, and the data entered into the Interior Collections Management System (ICMS) according to NPS Museum Handbook requirements to meet or exceed accountability standards and for submission to the NPS National Catalog.
