Flowering time is an important biological phenomenon, affecting human societies through its effects on agricultural crops, pollinators, pests, and biodiversity. Given the sensitivity of flowering times to climatic conditions, a thorough understanding of how plants respond to changing environments is necessary for predicting the consequences for pollinators, herbivores, parasites, and plant populations. A record of historical flowering times is found within the nation's herbaria – collections of dried and pressed plants. In 2018, the California Phenology Thematic Collections Network (CAP-TCN) was established to advance our understanding of flowering time changes over time. The network brought together 22 California universities, research stations, natural history collections, and botanical gardens, with the goal of imaging and recording the flowering status of approximately one million herbarium specimens collected over the past 150 years. These data are freely available through the newly established Consortium of California Herbaria (CCH2) portal. This project will add a partnership of seven new collections and six new institutions to the CAP-TCN, contributing an additional 150,000 herbarium specimens. The project participants will be fully integrated into CAP-TCN training and outreach activities including Notes from Nature online expeditions, which educate and involve members of the public in learning about herbarium specimens and flowering phenology. By expanding the geographic scope to encompass Oregon and the northern Baja California peninsula, the CAP-TCN will now cover the entire California Floristic Province, a biodiversity hotspot of global significance. This will increase the number of species with imaged specimens across their entire range from 1,217 to 1,850, a 55% increase. The addition of 80,000 Oregon and Baja California specimens to CCH2 will facilitate efficient specimen-based analyses of the entire California Floristic Province and for the first time allow a more objective and reproducible specimen-based delineation of its geographic boundaries. Three institutions in California and Nevada will fill key geographic gaps for northwestern California, the northern San Joaquin Valley, and the Mojave Desert. Two additional institutions will significantly increase CAP-TCN representation of 1) the ecologically important and taxonomically complex genus Arctostaphylos (manzanita); and 2) introduced and invasive species of importance to California agriculture, rangelands, and native ecosystems. An estimated 25 additional undergraduates will participate in digitizing activities. Ongoing public outreach efforts about the floras of Oregon and Baja California at Oregon State University and the San Diego Natural History Museum will also benefit from the newly imaged specimens. Data will be shared through online resources, including iDigBio.org.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

开花时间是一种重要的生物学现象，通过对农作物，传粉媒介，害虫和生物多样性的影响影响人类社会。鉴于开花时间对慢性疾病的敏感性，对植物对不断变化的环境的反应的透彻理解对于预测授粉媒介，食草动物，寄生虫和植物种群的后果是必要的。在该国的草药中发现了历史开花时期的记录 - 干和压力的植物收藏。 2018年，建立了加利福尼亚物候学主题网络（CAP-TCN），以促进我们对开花时间随时间变化的理解。该网络汇集了22所加利福尼亚大学，研究站，自然历史收藏品和植物园，目的是成像和记录过去150年来收集的大约100万个草药标本的开花状态。这些数据可通过新成立的加利福尼亚草药（CCH2）门户免费获得。该项目将为CAP-TCN增加七个新收藏和六个新机构的合作伙伴关系，并贡献了15万名草药标本。项目参与者将完全纳入CAP-TCN培训和外展活动，包括来自自然在线探险的笔记，这些笔记是教育性的，并让公众参与了解植物标本室标本和开花候位物质。通过将地理范围扩展到俄勒冈州和北巴哈加州半岛，Cap-TCN现在将覆盖整个加利福尼亚植物省，这是具有全球意义的生物多样性热点。这将增加整个范围内成像标本的物种数量从1,217增加到1,850，增加了55％。在CCH2中增加了80,000个俄勒冈州和加利福尼亚州的规格，将促进整个加利福尼亚植物省的有效标本的分析，并首次允许基于地理界限的基于客观，更可重复的标本的描述。加利福尼亚和内华达州的三个机构将填补加利福尼亚西北部，北圣华金山谷和莫哈韦沙漠的关键地理空白。另外两个机构将大大增加。 1）cap-TCN表示，生态重要和分类学复杂的arctostaphylos属（Manzanita）； 2）对加利福尼亚农业，牧场和本地生态系统引入和入侵物种。估计还有25名本科生将参加数字化活动。俄勒冈州立大学和圣地亚哥自然历史博物馆的俄勒冈州和加利福尼亚州植物园的持续公开外展工作也将从新成像的标本中受益。数据将通过在线资源共享，包括idigbio.org。该奖项反映了NSF的法定使命，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估，被认为是珍贵的支持。
