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

亚利桑那大学的树木年轮研究实验室（LTRR）拥有世界上最大和最多样化的树木年轮研究（树木年代学）标本。75年来，LTRR基本上是一个“木材标本馆”，包含大约2，000，000个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。该项目将通过按照现行档案标准重新安置和购买高密度密集书架，确保收藏品的长期安全、组织和可获得性。这些书架将安装在一座经过翻修的档案大楼内，大大改善了人们获取大量研究、教育和宣传材料的机会。树木年轮是自然的计时器，记录着与生物生命息息相关的环境变化。LTRR系列是对气候变化，水资源，火灾生态和人类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，这些见解通常是无法获得的。物理压缩和组织LTRR集合将分配空间用于公共活动，包括展览和举办学校实地考察。通过图尔斯参观和免费巡回展览的形式，促进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.
