Ferns and their relatives ("pteridophytes") arose approximately 420 million years ago and were the dominant plant groups for hundreds of millions of years afterwards. Today the pteridophytes are outnumbered by the diversity and abundance of other plant groups, such as those that bear flowers, but they remain diverse (with around 12,000 species), ecologically important, and are found throughout the world. This Thematic Collections Network (TCN) brings together 9 core institutions whose goal is to make digital images and data on the distribution and biology of 1.6 million fossil and modern ferns and their relatives available to researchers. This effort includes 39 US Museums and Herbaria that will provide on-line access of collections data to researchers worldwide who will be able to address pressing questions about the evolution, distribution, and biology of land plants. This project would train students and reach the public through teacher training opportunities, the development of curriculum and education boxes and through the production of informative science videos. The Pteridological Collections Consortium TCN is an interdisciplinary initiative that will database, image, and disseminate information on an unprecedented number of extant and fossil pteridophyte specimens. The combining of neo- and paleobotanical collections data will produce an online resource via a Symbiota framework to enable research on the distribution, ecology, genetics, and deep-time evolution of an important group of vascular plants. Pteridophytes are important because they 1) are relatively diverse and have extensive global distributions, 2) are associated with evolutionary innovations that shaped adaptations to terrestrial ecosystems, 3) they are sensitive to local environmental conditions and play important roles in modern communities, and 4) they have an excellent fossil record for addressing deep-time questions. This award is made as part of the National Resource for Digitization of Biological Collections through the Advancing Digitization of Biological Collections program and all data resulting from this award will be available through the national resource (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.

蕨类植物和它们的亲戚（“蕨类植物”）大约在4.2亿年前出现，在之后的数亿年里一直是主要的植物群。今天，蕨类植物在数量和数量上都不及其他植物群，如开花植物，但它们仍然保持多样性（约有12,000种），具有重要的生态意义，分布在世界各地。这个专题收藏网络（TCN）汇集了9个核心机构，其目标是为研究人员提供160万种化石和现代蕨类植物及其近亲的分布和生物学的数字图像和数据。这项工作包括39家美国博物馆和植物标本馆，它们将为世界各地的研究人员提供馆藏数据的在线访问，他们将能够解决有关陆地植物进化、分布和生物学的紧迫问题。该项目将通过教师培训机会、课程和教育盒的开发以及制作信息科学视频来培训学生并接触公众。蕨类收藏联盟（TCN）是一个跨学科的倡议，将对数量空前的现存和化石蕨类标本进行数据库、图像和信息传播。通过Symbiota框架，将新植物和古植物收集数据结合在一起，将产生一个在线资源，使研究一个重要维管植物群的分布、生态学、遗传学和深时间进化成为可能。蕨类植物是重要的，因为它们1)相对多样化，具有广泛的全球分布；2)与进化创新有关，形成了对陆地生态系统的适应；3)它们对当地环境条件敏感，在现代社区中发挥重要作用；4)它们有很好的化石记录，可以解决深时间问题。该奖项是通过推进生物馆藏数字化计划的国家生物馆藏数字化资源的一部分，该奖项产生的所有数据将通过国家资源（iDigBio.org）获得。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
