CSBR: Natural History Collections: Urgent Improvements to Housing and Accessibility of the World's Largest, Most Diverse & Significant Dendrochronological Collection

亚利桑那大学树轮研究实验室(LTRR)拥有世界上最大和最多样化的树轮研究(树轮年代学)标本收藏。75年来，LTRR基本上一直是一个“木材标本馆”，收藏了大约200万份研究标本和相关材料。目前，近一半的藏品存放在风险极高的仓库中，甚至缺乏基本的供暖或空调控制。该项目将通过重新安置到目前的档案标准，并通过购买高密度的紧凑型架子，确保藏品的长期安全、组织和可获得性。这个架子将被安装在一座翻新的档案馆里，为研究、教育和户外活动提供更多的材料。树轮是自然的计时器和环境变化的记录器，生物生命不可避免地与之联系在一起。LTRR收藏品是关于气候变化、水资源、火生态和人与环境相互作用的物理、生物和历史见解的不可替代的来源，否则往往无法获得。实际浓缩和组织LTRR收藏品将分配空间用于公共活动，包括展览和举办学校实地考察。通过参观和创建免费的巡回展览，促进了公众与科学收藏品的互动、教育和接触。

The University of Arizona's Laboratory of Tree-Ring Research (LTRR) maintains the largest and most diverse collection of tree-ring research (dendrochronology) specimens in the world. For 75 years, the LTRR has essentially served as a "wood herbarium", containing approximately 2,000,000 research specimens and associated materials. Nearly half of the collection currently resides in extremely high-risk storage, lacking even basic heating or air conditioning controls. This project will secure the long-term safety, organization and accessibility of the collection through re-housing to current archival standards and via the purchase of high-density compact shelving. The shelving will be installed in a renovated archive building, providing greatly improved access to a wealth of materials for research, education and outreach.Tree rings are natural chronometers and recorders of change in the environment with which biological life is inescapably linked. The LTRR collection is an irreplaceable source of physical, biological and historical insights on climate change, water resources, fire ecology, and human-environment interactions that are often otherwise unobtainable. Physically condensing and organizing the LTRR collection will allot space for public activities, including exhibits and hosting school field trips. Public interaction with, education of and exposure to scientific collections is facilitated in the form of tours and the creation of no-cost travelling exhibits.
